**Construction Specification 9---Traffic Control**

**1. Scope**

The work shall consist of establishing traffic control and maintaining
safe, convenient use of public roads and rights-of-way.

**2. Traffic and access**

The contractor\'s operations shall cause no unnecessary inconvenience to
the public. The public rights-of-way shall be maintained at all times
unless interruption is authorized by proper local authority.
Contractor\'s authorized closing or detour plans shall be provided to
the engineer for approval.

Safe and adequate access shall be provided and maintained to all public
protection devices and to all critical utility control locations.
Facility access shall be continuous and unobstructed unless otherwise
approved.

**3. Storage of equipment and material in public streets**

Construction materials and equipment shall not be stored or parked on
public streets, roads, or highways. During any material or equipment
loading or unloading activities that may temporarily interfere with
traffic, an acceptable detour shall be provided for the duration of the
activity. Any associated expense for this activity is the responsibility
of the contractor.

Excavated material, including suitable material that is intended for
adjacent trench backfill or other earth backfill as specified in section
5 of this specification, shall not be stored on public streets, roads,
or highways that remain in service for the public. Any waiver of this
requirement must be obtained from the proper local authority and
approved by the engineer. All excess and unsuitable material shall be
removed from the site as soon as possible. Any spillage shall be removed
from roadways before they are used by the public.

**4. Street closures, detours, and barricades**

The contractor shall comply with the requirements of all applicable
responsible units of government for closure of any street, road, or
highway. The contractor shall provide the required barriers, guards,
lights, signs, temporary bridges, and flaggers together with informing
the public of any detours and construction hazards by the most suitable
means available, such as local newspapers or radio stations. The
contractor is also responsible for compliance with additional public
safety requirements that may arise during construction. The contractor
shall furnish, install, and, upon completion of the work, promptly
remove all signs, warning devices, and other materials used in the
performance of this work.

Unless otherwise specified, the contractor shall notify, in writing, the
fire chief, police chief, county sheriff, state patrol, schools that
operate school buses, or any other government official as may be
appropriate no less than 7 days before closing, partly closing, or
reopening any street, road, or highway.

Unless otherwise specified, the contractor shall furnish to the engineer
a written plan showing the proposed method of signing, barricading for
traffic control, and safety for street detours and closures.

All temporary detours will be maintained to ensure use of public
rights-of-way is provided in a safe manner. This may include dust
control, grading, and graveling as required in section 7 of this
specification.

**5. General and specific references**

All signs, signals, barricades, use of flaggers, and other traffic
control and public safety devices shall conform to the general
requirements set forth in the Manual of Uniform Traffic Control Devices
(MUTCD) and the latest edition of *Standard Highway Signs and Standard
Alphabets for Highway Signs* and/or OSHA *Construction Industry
Standards (29 CFR Part 1926), Subpart G, Signs, Signals, and Barricades*
unless otherwise specified in section 7 of this specification.

**6. Measurement and payment**

For items of work for which specific lump sum prices are established in
the contract, payment for the work is made at the contract lump sum
price. Progress payments will be made based upon the percentage of
estimated total time that traffic control will be required unless
otherwise specified in section 7 of this specification. Payment will
constitute full compensation for all flaggers, labor, materials,
equipment, and all other items necessary and incidental to completion of
the work.

Compensation for any item of work described in the contract, but not
listed in the bid schedule will be included in the payment for the item
of work to which it is made subsidiary. Such items and items to which
they are made subsidiary are identified in section 7 of this
specification.
