The department announced this week that two additional southbound lanes will open from the Rock Street overpass to River Road in New Braunfels. The change will take effect Nov. 22 at 9 a.m.
The Rock Street entrance ramp onto southbound Loop 337 will open at the same time.
Drivers accessing northbound Loop 337 from River Road will see no change, according to a TxDOT news release.
Drivers will also see a newly operating traffic signal at the intersection of Loop 337 and River Road.
“Drivers who may be accustomed to passing through this intersection without stopping are advised to use caution and adhere to the new traffic signal,” the release said.
TxDOT crews continue to work on the final section of Loop 337 southbound lanes from Hwy. 46 to Oak Run Parkway with an expected completion date of early 2020.
According to the release, upgrades to existing southbound Loop 337 lanes will take place in areas where southbound traffic has been shifted to newly opened lanes. One northbound lane will remain open, and TxDOT has placed road signs to help drivers navigate any new roadway configurations.
“TxDOT asks the traveling public to adhere to construction signage and remain aware and use caution when traveling through,” the release said.
The Loop 337 project, which began in November 2017, is intended to upgrade approximately six miles of roadway from a two-lane to a four-lane highway, including new bridge construction and pedestrian accommodations.
