San Marcos Transportation Corridors Study

The Capital Area Metropolitan Planning Organization (CAMPO) and the City of San Marcos are partnering on the San Marcos Transportation Corridors Study to identify and plan for future needs and recommend improvements along three key roadways in the area.

Study Area Updates-R3d

The San Marcos Transportation Corridors Study will evaluate Guadalupe Street (SH 123), Hopkins Street (SH 80), and a potential north/south thoroughfare east of IH 35 and propose ideas for future development and transportation improvements. These concepts will focus development and redevelopment at important centers such as the downtown area, the Medical Center, and the City Government complex.


To comply with social distancing guidelines, public participation and commenting will take place remotely. The first Virtual Open House was available from August 31, 2020 - October 12, 2020. A second public input opportunity was open May 3, 2021 - June 4, 2021. The third input opportunity was open from November 2, 2021 - December 3, 2021.
