Title 33—Navigation and Navigable Waters--Volume 1
PART 117—DRAWBRIDGE OPERATION REGULATIONS
§ 117.1   Purpose.
(a) This part prescribes the general and special drawbridge operating regulations that apply to the drawbridges across the navigable waters of the United States and its territories. The authority to regulate drawbridges across the navigable waters of the United States is vested in the Secretary of Homeland Security.
(b) Subpart A contains the general operation requirements that apply to all drawbridges.
(c) Subpart B contains specific requirements for operation of individual drawbridges. These requirements are in addition to or vary from the general requirements in Subpart A. Specific sections in subpart B that vary from a general requirement in Subpart A supersede the general requirement. All other general requirements in Subpart A, that are not at variance, apply to the drawbridges and removable span bridges listed in Subpart B.
§ 117.4   Definitions.
The following definitions apply to this part:
Appurtenance means an attachment or accessory extending beyond the hull or superstructure that is not an integral part of the vessel and is not needed for a vessel's piloting, propelling, controlling, or collision avoidance capabilities.
Automated drawbridge means a drawbridge that is operated by an automated mechanism, not a drawtender. An automated drawbridge is normally kept in the open to navigation position and closes when the mechanism is activated.
Deviation means a District Commander's action authorizing a drawbridge owner to temporarily not comply with the drawbridge opening requirements in this part.
Drawbridge means a bridge with an operational span that is intended to be opened for the passage of waterway traffic.
Drawspan means the operational span of a drawbridge.
Lowerable means a non-structural vessel appurtenance that is or can be made flexible, hinged, collapsible, or telescopic so that it can be mechanically or manually lowered.
Nonstructural means that the item is not rigidly fixed to the vessel and can be relocated or altered.
Not essential to navigation means that a nonstructural vessel appurtenance, when in the lowered position, would not adversely affect the vessel's piloting, propulsion, control, or collision-avoidance capabilities.
Public vessel means a vessel that is owned and operated by the United States Government and is not engaged in commercial service, as defined in 46 U.S.C. 2101.
Remotely operated drawbridge means a drawbridge that is operated by remote control from a location away from the drawbridge.
Removable span bridge means a bridge that requires the complete removal of a span by means other than machinery installed on the bridge to open the bridge to navigation.
Untended means that there is no drawtender at the drawbridge.
§ 117.5   When the drawbridge must open.
Except as otherwise authorized or required by this part, drawbridges must open promptly and fully for the passage of vessels when a request or signal to open is given in accordance with this subpart.
§ 117.7   General requirements of drawbridge owners.
Except for drawbridges that have been authorized, before January 3, 2007, to remain closed to navigation or as otherwise specified in subpart B, drawbridge owners must:
(a) Provide the necessary drawtender(s) for the safe and prompt opening of the drawbridge.
(b) Maintain the working machinery of the drawbridge in good operating condition.
(c) Cycle the drawspan(s) periodically to ensure operation of the drawbridge.
(d) Ensure that the drawbridge operates in accordance with the requirements of this part.
(e) Any drawbridge allowed to remain closed to navigation prior to January 3, 2007, when necessary, must be returned to operable condition within the designated time set forth by the District Commander and will become subject to the requirements of this part.
§ 117.8   Permanent changes to drawbridge operation.
(a) Anyone may submit a written request to the District Commander for a permanent change to a drawbridge operating requirement. The request must include documentation supporting or justifying the requested change.
(b) If after evaluating the request, the District Commander determines that the requested change is not needed, he or she will respond to the request in writing and provide the reasons for denial of the requested change.
(c) If the District Commander decides that a change may be needed, he or she will begin a rulemaking to implement the change.
§ 117.9   Delaying opening of a draw.
No person shall unreasonably delay the opening of a draw after the signals required by § 117.15 have been given.
Trains are usually controlled by the block method. That is, the track is divided into blocks or segments of a mile or more in length. When a train is in a block with a drawbridge, the draw may not be able to open until the train has passed out of the block and the yardmaster or other manager has “unlocked” the drawbridge controls. The maximum time permitted for delay is defined in Subpart B for each affected bridge. Land and water traffic should pass over or through the draw as soon as possible in order to prevent unnecessary delays in the opening and closure of the draw.
§ 117.11   Unnecessary opening of the draw.
No vessel owner or operator shall—
(a) Signal a drawbridge to open if the vertical clearance is sufficient to allow the vessel, after all lowerable nonstructural vessel appurtenances that are not essential to navigation have been lowered, to safely pass under the drawbridge in the closed position; or
(b) Signal a drawbridge to open for any purpose other than to pass through the drawbridge opening.
§ 117.15   Signals.
(a) General. (1) The operator of each vessel requesting a drawbridge to open shall signal the drawtender and the drawtender shall acknowledge that signal. The signal shall be repeated until acknowledged in some manner by the drawtender before proceeding.
(2) The signals used to request the opening of the draw and to acknowledge that request shall be sound signals, visual signals, or radiotelephone communications described in this subpart.
(3) Any of the means of signaling described in this subpart sufficient to alert the party being signaled may be used.
(b) Sound signals. (1) Sound signals shall be made by whistle, horn, megaphone, hailer, or other device capable of producing the described signals loud enough to be heard by the drawtender.
(2) As used in this section, “prolonged blast” means a blast of four to six seconds duration and “short blast” means a blast of approximately one second duration.
(3) The sound signal to request the opening of a draw is one prolonged blast followed by one short blast sounded not more than three seconds after the prolonged blast. For vessels required to be passed through a draw during a scheduled closure period, the sound signal to request the opening of the draw during that period is five short blasts sounded in rapid succession.
(4) When the draw can be opened immediately, the sound signal to acknowledge a request to open the draw is one prolonged blast followed by one short blast sounded not more than 30 seconds after the requesting signal.
(5) When the draw cannot be opened immediately, or is open and shall be closed promptly, the sound signal to acknowledge a request to open the draw is five short blasts sounded in rapid succession not more than 30 seconds after the vessel's opening signal. The signal shall be repeated until acknowledged in some manner by the requesting vessel.
(c) Visual signals. (1) The visual signal to request the opening of a draw is—
(i) A white flag raised and lowered vertically; or
(ii) A white, amber, or green light raised and lowered vertically.
(2) When the draw can be opened immediately, the visual signal to acknowledge a request to open the draw, given not more than 30 seconds after the vessel's opening signal, is—
(i) A white flag raised and lowered vertically;
(ii) A white, amber, or green light raised and lowered vertically; or
(iii) A fixed or flashing white, amber, or green light or lights.
(3) When the draw cannot be opened immediately, or is open and must be closed promptly, the visual signal to acknowledge a request to open the draw is—
(i) A red flag or red light swung back and forth horizontally in full sight of the vessel given not more than 30 seconds after the vessel's opening signal; or
(ii) A fixed or flashing red light or lights given not more than 30 seconds after the vessel's opening signal.
(4) The acknowledging signal when the draw cannot open immediately or is open and must be closed promptly shall be repeated until acknowledged in some manner by the requesting vessel.
(d) Radio telephone communications. (1) Radiotelephones may be used to communicate the same information provided by sound and visual signals.
(2) The vessel and the drawtender shall monitor the frequency used until the vessel has cleared the draw.
(3) When radiotelephone contact cannot be initiated or maintained, sound or visual signals under this section shall be used.
§ 117.17   Signalling for contiguous drawbridges.
When a vessel must past two or more drawbridges close together, the opening signal is given for the first bridge. After acknowledgment from the first bridge that it will promptly open, the opening signal is given for the second bridge, and so on until all bridges that the vessel must pass have been given the opening signal and have acknowledged that they will open promptly.
§ 117.19   Signalling when two or more vessels are approaching a drawbridge.
When two or more vessels are approaching the same drawbridge at the same time, or nearly the same, time, whether from the same or opposite directions, each vessel shall signal independently for the opening of the draw and the drawtender shall reply in turn to the signal of each vessel. The drawtender need not reply to signals by vessels accumulated at the bridge for passage during a scheduled open period.
§ 117.21   Signalling for an opened drawbridge.
When a vessel approaches a drawbridge with the draw in the open position, the vessel shall give the opening signal. If no acknowledgment is received within 30 seconds, the vessel may proceed, with caution, through the open draw.
§ 117.23   Installation of radiotelephones.
(a) When the District Commander deems it necessary for reasons of safety of navigation, the District Commander may require the installation and operation or a radiotelephone on or near a drawbridge.
(b) The District Commander gives written notice of the proposed requirement to the bridge owner.
(c) All comments the owner wishes to submit shall be submitted to the District Commander within 30 days of receipt of the notice under paragraph (b) of this section.
(d) If, upon consideration of the comments received, the District Commander determines that a radiotelephone is necessary, the District Commander notifies the bridge owner that a radiotelephone shall be installed and gives a reasonable time, not to exceed six months, to install the radiotelephone and commence operation.
§ 117.24   Radiotelephone installation identification.
(a) The Coast Guard authorizes, and the District Commander may require the installation of a sign on drawbridges, on the upstream and downstream sides, indicating that the bridge is equipped with and operates a VHF radiotelephone in accordance with § 117.23.
(b) The sign shall give notice of the radiotelephone and its calling and working channels—
(1) In plain language; or
(2) By a sign consisting of the outline of a telephone handset with the long axis placed horizontally and a vertical three-legged lightning slash superimposed over the handset. The slash shall be as long vertically as the handset is wide horizontally and normally not less than 27 inches and no more than 36 inches long. The preferred calling channel should be shown in the lower left quadrant and the preferred working channel should be shown in the lower right quadrant.
It is recommended that the radiotelephone sign be similar in design to the Service Signs established by the Federal Highway Administration (FHWA) in U.S. Road Symbol Signs using Reflective Blue and Reflective White colors. Color and design information is available from the District Commander of the Coast Guard District in which the bridge is located.
§ 117.31   Drawbridge operations for emergency vehicles and emergency vessels.
(a) Upon receiving notification that an emergency vehicle is responding to an emergency situation, a drawtender must make all reasonable efforts to have the drawspan closed at the time the emergency vehicle arrives.
(b) When a drawtender receives notice, or a proper signal as provided in § 117.15 of this part, the drawtender shall take all reasonable measures to have the draw opened, regardless of the operating schedule of the draw, for passage of the following, provided this opening does not conflict with local emergency management procedures which have been approved by the cognizant Coast Guard Captain of the Port:
(1) Federal, State, and local government vessels used for public safety;
(2) Vessels in distress where a delay would endanger life or property;
(3) Commercial vessels engaged in rescue or emergency salvage operations; and
(4) Vessels seeking shelter from severe weather.
§ 117.33   Closure of draw for natural disasters or civil disorders.
Drawbridges need not open for the passage of vessels during periods of natural disasters or civil disorders declared by the appropriate authorities unless otherwise provided for in Subpart B or directed to do so by the District Commander.
§ 117.35   Temporary change to a drawbridge operating schedule.
(a) For any temporary change to the operating schedule of a drawbridge, lasting less than or equal to 180 days, the District Commander may issue a deviation approval letter to the bridge owner and publish a “Notice of temporary deviation from regulations” in the Federal Register.
(b) If the time period for a temporary change to the operating schedule of a drawbridge will be greater then 180 days, the District Commander will follow appropriate rulemaking procedures and publish a temporary rule in the Federal Register prior to the start of the action.
(c) Request for change. (1) To temporarily change the drawbridge-operating requirements the bridge owner must submit a written request to the District Commander for approval of the change.
(2) The request must describe the reason for the deviation and the dates and times scheduled for the start and end of the change.
(3) Requests should be submitted as early as possible, preferably 90 days before the start of the action. District Commanders have discretion to accept requests submitted less than 90 days before a needed change if those requests can be processed before the date of the needed change.
(d) Determination. The District Commander's determination to allow the schedule change is normally forwarded to the bridge owner within ten working days after receipt of the request. If the request is denied, the reasons for the denial will be set out in the District Commander's decision letter.
(e) The drawbridge must return to its regular operating schedule immediately at the end of the designated time period.
(f) If the authorized deviation period for an event is broken into separate time periods on the same day or on consecutive days, the drawbridge must provide openings for navigation between authorized schedule changes.

§ 117.121   Arkansas River.
The draw of the Missouri Pacific Railroad bridge, mile 23.1 near Yancopin, shall open on signal if at least 96 hours notice is given.
§ 117.123   Arkansas Waterway.
(a) Across the Arkansas Waterway, the draw of the Rob Roy Drawbridge, mile 67.4, at Pine Bluff, Arkansas is maintained in the closed to navigation position and is remotely operated. Any vessel which requires an opening of the draw of this bridge shall establish contact by radiotelephone with the remote drawbridge operator on VHF-FM Channel 12 in Omaha, Nebraska. To establish contact, the vessel shall key the VHF-FM radio microphone four times in five seconds and listen for an acknowledgement tone. The remote drawbridge operator will then establish normal verbal radio communication on VHF-FM Channel 12 and advise the vessel whether the requested span can be immediately opened and will maintain constant radio contact with the vessel until the requested span has opened and vessel passage has been completed. The bridge is equipped with a Photoelectric Boat Detection System to prevent the span from lowering if there is an obstruction under the span. If the drawbridge cannot be opened immediately, the remote drawbridge operator will notify the calling vessel and provide an estimated time for a drawspan opening.
(b) Across the Arkansas Waterway, the draw of the Baring Cross Railroad Drawbridge, mile 119.6 at Little Rock, Arkansas, is maintained in the closed position and is remotely operated. Use the following procedures to request an opening of this bridge when necessary for transit:
(1) Normal flow procedures. Any vessel which requires an opening of the draw of this bridge shall establish contact by radiotelephone with the remote drawbridge operator on VHF-FM Channel 13 in Omaha, Nebraska. To establish contact, the vessel shall key the VHF-FM radio microphone four times in five seconds and listen for an acknowledgement tone. The remote drawbridge operator will then establish normal verbal radio communication on VHF-FM Channel 13 and advise the vessel whether the requested span can be immediately opened and will maintain constant radio contact with the vessel until the requested span has opened and vessel passage has been completed. The bridge is equipped with a Photoelectric Boat Detection System to prevent the span from lowering if there is an obstruction under the span. If the drawbridge cannot be opened immediately, the remote drawbridge operator will notify the calling vessel and provide an estimated time for a drawspan opening.
(2) High velocity flow procedures. The area from mile 118.2 to mile 125.4 is a regulated navigation area as described in § 165.817. During periods of high velocity flow rate of 70,000 cubic feet per second or greater at the Murray Lock and Dam, mile 125.4, downbound vessels which require that the draw of this bridge be opened for unimpeded passage shall contact the remote drawbridge operator as described in paragraph (b)(1) of this section either before departing Murray Lock and Dam or before departing the mooring cells at mile 121.5 to ensure that the drawspan is opened well in advance of arrival at the bridge. The remote drawbridge operator shall immediately respond to the vessel's contact, ensure the drawspan is open for passage, and ensure that it remains in the open to navigation position until the downbound vessel has safely passed through. If it cannot be opened immediately for unimpeded passage in accordance with § 165.817, the remote drawbridge operator will notify the downbound vessel and provide an estimated time for a drawspan opening.

(v) A siren for sound signals; and
(vi) Red and green center span navigation lights.
(3) The remote bridge operator shall maintain a 24 hour VHF marine radio watch for mariners to establish contact as they approach the bridge to ensure that the drawspan is open or that it remains open until passage of river traffic is complete.
(4) When rail traffic approaches the bridge, and the drawspan is in the open position, the remote bridge operator initiates a one minute warning period before closing the drawspan. During this warning period, the remote operator shall broadcast at least twice, via marine radio, that: “The drawspan of the EJ&E Railroad bridge will be lowered in one minute.” A siren on the bridge sounds for 20 seconds, to warn anyone on or under the bridge that the drawspan will be lowered.
(5) If a vessel is approaching the bridge upbound or, departing the Lockport Lock and Dam at mile 291.1, downbound, with intentions of passing through the drawspan, they shall respond to the remote bridge operators' marine radio broadcast, or initiate radio contact, indicating their proximity to the bridge and requesting an opening of the drawspan or that the drawspan remain open until the vessel passes.
