From 5 a.m. on each Saturday morning through 11:59 p.m. on each Sunday evening the bridge will open on signal on the hour only. Vessels that can pass under the draw without a bridge opening may do so at all times. This deviation is necessary to facilitate bridge track repairs.

# SUPPLEMENTARY INFORMATION:

The MBCR/Amtrak Bridge, across the Charles River, mile 0.8, at Boston, Massachusetts, has a vertical clearance in the closed position of 3 feet at mean high water and 12 feet at mean low water. The existing drawbridge operation regulations are listed at 33 CFR 117.591(c). 

The owner of the bridge, the Massachusetts Bay Commuter Railroad (MBCR), requested a temporary deviation to facilitate repairs to the bridge rails. 

Under this temporary deviation, in effect from Friday, April 27, 2007 through Sunday May 20, 2007, the MBCR/Amtrak Bridge need not open for the passage of vessel traffic from 11:59 p.m. on each Friday evening through 5 a.m. each Saturday morning. From 5 a.m. each Saturday morning through 11:59 p.m. each Sunday evening the bridge shall open on signal, on the hour only. Vessels that can pass under the bridge without a bridge opening may do so at all times. 

This deviation from the operating regulations is authorized under 33 CFR 117.35. 

                    Should the bridge maintenance authorized by this temporary deviation be completed before the end of the effective period published in this notice, the Coast Guard will rescind the remainder of this temporary deviation, and the bridge shall be returned to its normal operating schedule. Notice of the above action shall be provided to the public in the Local Notice to Mariners and the                     **Federal Register**                    , where practicable.
