Traffic Control Plan (TCP)
To minimize inconvenience to the traveling public the limits of each phase
shall be followed.
The TCP is divided into phases and steps. See Traffic Control Plans for
additional and specific details of phases, steps and sequencing.
Work on Phase I will not commence until, in the opinion of the Engineer,
sufficient material, equipment, machinery and additional resources required
to insure continuity in the progress of work have been fabricated and/or
stored and approved for use.
Phase 1 - Step 1A

of construction. Full pavement markings matching the existing markings shall
be placed on this new overlay. Work shall begin on the relocation of all
utilities on both sides of the project.

plans. Temporary connections shall be built between the new westbound
frontage road and the existing frontage road as shown in the plans. Portions
of the existing westbound frontage road shall be widened as shown on the
plans. The new fiber optic cable trunk line along this portion of the
westbound frontage road shall be installed as early as possible. Construct
the temporary ramp from the westbound mainlanes to the westbound frontage
road. Build the portions of proposed U.S. 90 and Katy-Fort Bend Road as shown
