I-10 HOV, Managed Lanes (TxDOT)

I-10 HOV, Managed Lanes (TxDOT)

Role: Subconsultant   |   Client: TxDOT, San Antonio District

This was a high-profile, added capacity project that included the addition of one general-purpose lane and one HOV lane in each direction on I-10 from FM 3351 (Ralph Fair Road) to La Cantera Parkway. PCI was contracted as a subconsultant to construct managed lanes within the center median of I-10 while also maintaining the existing main lanes for general-purpose use. The additional pavement width necessary to accommodate the proposed managed lanes would be constructed by adding pavement in the median, and in some other areas, widening them along the outside edges; thus, requiring pavement restriping. All improvements were proposed within the existing right-of-way (ROW). The project proximity was also close to Camp Bullis, requiring coordination with the military.

The PCI environmental team prepared the TxDOT Environmental Assessment (EA) and corresponding technical reports for this project. The environmental analysis included impacts to five waters of the U.S. (WOUS), traffic noise impacts, “May Effect, Likely to Adversely Affect” three federally-endangered species requiring USFWS formal consultation, location of the project within the Edwards Aquifer Recharge Zone, extra coordination due to original tolling components of the project. The team also provided public involvement that included a public meeting and hearing. 

“I am very proud of the quality of work that came out of this effort. It was prepared to withstand challenges.”

Mr. John Bryant, TxDOT San Antonio District Environmental Coordinator
