I 10 State Highway Improvements

Austin and Waller Counties, Texas

Controlling traffic during a major expansion of I-10, just west of Houston, was a critical element in maintaining safety and keeping this heavily traveled corridor open to vehicles during construction. DECON developed a Traffic Control Plan (TCP) for three miles of the 16-mile program to maximize safety through the practical usage of signage and recommending safe speed limits.

DECON’S TCP for I-10 Segment 1 from STA 535+00 to STA 692+00 provided temporary exit/entrance ramps from STA 160+00 to STA 535+00. DECON supervised roadway plans and profiles for I-10 main lanes, frontage roads, and auxiliary roads, including rebuilt overpasses, which required extensive coordination with drainage designers.

This program involved extensive work on I-10, from FM 359 in Waller County to FM-3538 in Austin and Waller Counties. It included reconstruction of the freeway, adding one additional through lane in each direction, and replacing the bridges over the Brazos River. Overpasses were rebuilt to provide extra clearance, and the existing two-way frontage road system was converted to one-way.

DECON’s traffic plan played a vital role in providing continuous safe passage for the high volume of traffic and managing the access and exit of construction equipment during this significant program.
