I-35 Reconstruction

RPS was selected by the Texas Department of Transportation to design the expansion of IH-35 in Salado, Texas, one of the most heavily traveled and dangerous rural interstate highways in the country. The purpose of the project was to upgrade the facility, which was constructed in 1955, to current Interstate standards.

The interstate was expanded from four to six lanes, new bridges over Salado Creek were designed and frontage roads were converted from two-way to one-way traffic lanes. Adding to the project’s complexity was its proximity to a high number of historic sites in the area and the environmentally sensitive Salado Creek.
