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.
The project included three direct connectors on SH 130, including one at SH 45 SE north of Mustang Ridge, one at IH-10, and one at US 183 north of Lockhart. Aguirre & Fields was responsible for the 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.
Additionally, Aguirre & Fields designed all 32 of the project’s retaining walls. The majority of the retaining walls were mechanically stabilized earth (MSE) systems with the exception of 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.
