With the Texas Transportation Commission adding the second South Padre Island causeway project to the highway system, accelerated development and construction of the new bridge and roadway can begin.
Texas Department of Transportation Pharr District Engineer Pete Alvarez has provided the following updates:
Location and Details:
The second causeway, designated as State Highway 4, will be situated 3 to 4 miles north of the existing Queen Isabella Memorial Bridge.
It will be located just north of the South Padre Island Convention Center and approximately 3 to 4 miles north of State Highway 100.
The new causeway will be a four-lane structure with a length of 8 miles, making the total project length 11 miles.
Collaboration and Funding:
The project is a result of collaboration between the Texas Department of Transportation (TxDOT), Cameron County, and the Cameron County Regional Mobility Authority.
Anticipated completion of environmental clearance is expected by the spring of 2026. This step is crucial to ensure that the project complies with environmental regulations and standards.
Timeline and Construction:
The construction timeline is estimated to be between 3 to 5 years from the present, meaning that construction could begin within this timeframe.
The estimated cost of the project is between $700 million to $1 billion. This range reflects the anticipated financial investment required for the construction of the new causeway. Local, state, and federal funding will help for the construction of the second causeway.
Public Involvement: Public meetings have already taken place, and there are plans for future public meetings with the possibility of another public hearing.
