$176.8 million



Zachry was awarded two Harris County Toll Road Authority (HCTRA) projects to widen and reconstruct southern portion of the Beltway 8 (BW8) tollway facility. Both projects widen the toll road from Southwest Freeway (US-59) to the north side of the Houston Ship Channel. This first project (Contract 338) begins South of Spencer Highway to North of Greenshadow Drive along the Sam Houston Tollway East. The second project (Contract 346) begins North of Greenshadow Drive and continues to Jacinto Port Road.

Scope of work includes concrete paving, bridge construction, drainage improvements, mechanically stabilized earth walls, water and sewer relocations, toll booths, high mast lightings and sound walls. These projects are a continuation of the ongoing HCTRA program to widen all of BW8 to at least three lanes in both directions.
