A project to expand 6.65 miles of Loop 337 in New Braunfels from I-35 to Hillcrest Drive is nearing completion after more than three years.

The project will widen the road from two to four lanes and will include a sidewalk and bike accommodation.

Work began on the project in 2017 and is scheduled to conclude in May, according to Jennifer Serold, public information officer for the Texas Department of Transportation’s San Antonio region.

Current work on the project is focused on placing intersections, installing signs and finalizing construction, Serold said.

The TxDOT and city of New Braunfels-funded project is expected to cost a total of $42.3 million upon completion and will help streamline traffic around the city.


Included in the Loop 337 expansion is a project to install a bridge and overpass that will raise Loop 337 over the River Road intersection.

The overpass will begin west of the Rock Street exit and end west of the River intersection.

Construction on the overpass began this month and is expected to be complete in the summer of 2023.

The project is estimated to cost approximately $14.2 million, according to TxDOT.
