San Antonio St. Bridge Reconstruction

The City of New Braunfels is taking a proactive approach by informing our residents about the upcoming San Antonio Street Bridge Reconstruction Project, managed by the Texas Department of Transportation. Project information and updates will be posted here as information becomes available. 


The upcoming improvements to the San Antonio Street Bridge will modernize the existing bridge to accommodate wider travel lanes and sidewalks while retaining the historical ambiance and architecture. Construction crews will begin placing equipment on August 1, 2019. 

Complete closure of the bridge will occur on September 3, 2019 and water recreation will not be allowed in the segment of the Comal River in the vicinity of the construction project beginning on September 23rd.

Comal River recreation beneath the bridge is expected to resume Memorial Day Weekend, 2020 while work continues above. The contractor will be using a seven day a week work schedule to expedite the project. Special care is being used to protect the environmentally sensitive waters of the Comal River, including the construction of a deck below the bridge to catch small debris before it can enter the waters.


The current bridge was built in 1923, with 10 foot wide lanes and 4 foot wide sidewalks. The project is needed because the bridge does not meet current structural and functional standards. The lack of shoulder and narrow sidewalks pose a safety risk for pedestrians and bicycles, the weight limit cannot support heavier vehicles, including emergency response vehicles impacting response times, and the travel lanes are not wide enough for large vehicles and bicycle users. The improved structure will allow for the passage of emergency vehicles and provide a much safer travel path for both vehicles and pedestrians.

Detour Traffic Routing & Tubing

The City is working with various mapping systems to ensure the closure and detours are in place for users.

The primary traffic detour route will utilize Comal, Garden and Lincoln to circumvent the bridge, but alternately, traffic may utilize N. Union to either Hinman Island Drive or Torrey St./Elizabeth, through Landa Park to avoid the closed bridge crossing.

River recreation will not be allowed in the immediate vicinity of the construction project beginning September 23rd and is expected to remain in place until Memorial Day weekend, 2020. Water recreation above and below the construction site on the Comal River will remain open, but no passage beneath the construction site vicinity will be allowed. Memorial Day Weekend, 2020, water recreation below the bridge is expected to resume, with work continuing on the bridge, above.

The project is expected to cost $4.5 Million with 80% Federal, 10% State, and 10% Local funding sources. The City’s 10% match was achieved through a credit on other local infrastructure projects.
