The current project is a study of the extension of the State Highway (SH) 130 from Mustang Ridge in Travis County to Interstate Highway 10 (I-10) near Seguin in Guadalupe County. The total of the SH-130 consists of 90 miles of highway developed in two parts: the first part consisting in approximately 50 miles and already has been constructed and the second part studied in this report, consists in the approximately 40 remaining miles divided in different segments, one of which has been studied in detail with a complete preliminary design for a future construction. Then, the overall scope of the project is double: (i) Study of the project alternatives for the SH 130 between Austin and San Antonio; solutions to face different challenges and problems encountered in the project design. (ii) Detailed study of an 8.821 miles segment (STA 2938+00 to STA 3375+23); provision of detailed design for construction of this segment as an example of the overall project The purpose of the SH 130 is to relieve congestion on I-35 and other major transportation facilities within the Austin - San Antonio corridor, improve mobility, and increase accessibility to important public facilities. Population growth within the Austin - San Antonio corridor during the last several decades, combined with a more recent intensification of interregional commerce, has led to unacceptable levels of congestion on I-35. The effects of this congestion (increased traffic fatalities and rising costs due to travel delays) suggest the need to take action. Other transportation problems in the corridor stem from a poorly developed roadway network that is constrained in its ability to meet the mobility and access needs of the corridor’s population and major public facilities. Development patterns in the corridor are highly car-dependent, with the availability of low cost land with access to IH35 encouraging urban sprawl. Over the last four decades, vehicle miles travelled have quadrupled, the number of vehicles has doubled, and the number of vehicles trips has increased by 50%. Average vehicle occupancies for work trips have decreased from 1.6 persons per vehicle in 1960 to 1.1 persons per vehicle in 1990.
