In a significant leap forward, the Texas Transportation Commission has officially designated the forthcoming roadway, SH 104, as part of the state highway system, signaling a momentous stride for the second South Padre Island causeway project. This move brings in additional funding avenues and accelerates the development and construction of the new bridge and roadway, envisioned to stretch between FM 106 and Park Road 100 on South Padre Island.
“The commission action today was an important first step for the planning, development, and construction of the second causeway project,” said Texas Transportation Commissioner Alex Meade.
“Like other projects around the state, if the second causeway project moves forward after the environmental review process it will require a significant partnership between TxDOT and local entities, including the CCRMA and the Rio Grande Valley MPO. Local partners will need to participate in providing significant local funding along with TxDOT funding to fund this project.”
Cameron County and the TxDOT Pharr District were the driving force behind naming SH 104 as part of the state highway system. They are committed to building a second causeway, which will be crucial for better handling hurricanes and emergencies.
Cameron County Judge Eddie Treviño, Jr. thanked Governor Abbott, TxDOT Chairman Bruce Bugg, and others for their support in making the SPI 2nd Causeway project a TxDOT On-System project.
Right now, TxDOT is the reviewing agency for the environmental document from the Cameron County Regional Mobility Authority (CCRMA), a project funded by working together with Cameron County, South Padre Island, and the CCRMA.
Environmental approval might come by fall 2026, opening the door for potential construction starting in 2029.
The current Queen Isabella Memorial Causeway, built in 1971, is the only road connecting South Padre Island to Port Isabel. This announcement is a big step in making the region's connections stronger and its infrastructure more resilient.
