This project was the first design-build “concession model” project ever constructed in Texas. The project provides relief of the gridlock on I-35, views of the rolling Texas landscapes, and a congestion-free cruise at 85 mph. SH 130 is 41 miles long, extending from Mustang Ridge to northeast of Seguin near IH-10 and had a development cost of $1.35 billion. It passes through Travis, Caldwell, and Guadalupe counties.

Aguirre & Fields was responsible for design of 16 bridges in and around the US 183 interchange including the NB US 183 to SB SH 130 direct connector. Three of the smaller overpass bridges were designed with skews in excess of 50 degrees. Five post-tensioned concrete straddle bents in excess of 100’ long were utilized within the US 183 interchange. Our team optimized bridge element sizes, developed design procedures for out-of-state offices not familiar with TxDOT practice, and resolved review comments at over-the-shoulder meetings.
Additionally, Aguirre & Fields designed all 32 of the project’s retaining walls. The majority of the retaining walls were mechanically stabilized earth (MSE) systems while there was one drilled shaft retaining wall. Aguirre & Fields also designed numerous miscellaneous foundations including those used for high mast illumination poles, large signs, and overhead gantries.
