South Padre Island Second Access Project (State Highway (SH)104, CSJ: 0775-02-002)

An environmental study is currently underway led by TxDOT (in collaboration with CCRMA) to explore alternate non-tolled connections from the Texas mainland, across the Laguna Madre, to South Padre Island.

The City of South Padre Island is located at the southern tip of Texas, on the eastern edge of Cameron County, approximately eight miles north of the Mexican border. South Padre Island stretches approximately 34 miles from the Port Mansfield Channel to Brazos Santiago Pass at its southern tip.

The Queen Isabella Memorial Causeway (SH 100) serves as the sole roadway connection to and from South Padre Island, presenting safety and mobility challenges during emergency evacuations. The purpose of the South Padre Island Second Access Project is to improve mobility and enhance public safety during emergency evacuations to/from the Texas mainland and South Padre Island.
