SAN ANTONIO, TX – STV today announced the Texas Department of Transportation (TxDOT) selected the firm to provide construction, engineering and inspection (CEI) services for the I-35 Northeast Expansion (NEX) program’s North project.  

The I-35 NEX program – consisting of North, Central and South projects – involves the construction of two elevated structures that will carry two general purpose lanes and one high-occupancy vehicle (HOV) lane in each direction. This expansion will improve safety and mobility while reducing commute times for the estimated 130,000 vehicles traveling on the 19.5 miles of roadway each day.  

For the North project, STV will provide roadway construction inspection, materials testing, project documentation and regulatory compliance support for 6.4-miles of the highway.  

“STV is proud to deliver infrastructure improvements that help make Cibolo stronger, safer and more connected,” said Nathan Terry, project manager at STV. “Our team will carefully coordinate overnight inspections for minimal impact on daily travel, so the community can continue using the roadway during peak travel hours.” 

With nearly half a century of local expertise, STV is the trusted team behind many of the new highways and transit systems in every major metropolitan region in Texas, including system-wide upgrades for the Houston Metropolitan Transit Authority’s New Starts light rail transit system. The firm also accomplished major milestones for TxDOT on each segment of the Capital Expressway improvement projects, including final plans delivery of CapEx South, planning for CapEx North and schematic and environmental support for CapEx Central. Most recently, STV celebrated the opening of the first major flyover ramp at Loop 1604 in San Antonio. Other key projects in Austin include US 290 Toll and SH 130 interchange and State Highway 45SW, a high-profile, award-winning TxDOT initiative.
