We're making great progress on the largest-scale construction project we currently have going in Comal County!
Talking about the Loop 337 expansion, which will widen it from two lanes to a four-lane divided highway.
Tomorrow afternoon (Tuesday, May 21), southbound traffic will be shifted to newly constructed southbound lanes between Hanz Drive and Rock Street, weather permitting. Crews will also re-open the newly-constructed exit ramp at Gruene Road.
To safely implement the traffic shift, drivers entering Loop 337 from River Terrace and Hanz Drive will be allowed to make right turns only. This is a permanent intersection change at River Terrace. At the end of this phase of construction, Hanz Drive will open as a traditional signalized intersection, allowing left turns.
Message signs are in place to inform drivers of this change and additional signage will be placed to help guide drivers safely travel along the roadway.
We ask the traveling public to follow construction signage and remain aware when driving through the work zone. As always, weather may impact the timing of these closures. We appreciate your patience and understanding as crews work to improve safety and mobility in the area.
Construction for the Loop 337 Expansion project began in November 2017 and is anticipated to be completed in late 2021.
The construction project is about six miles long, from I-35 to Hillcrest Drive. It includes an upgrade to a 4-lane divided roadway with pedestrian accommodations and new bridges in various locations.
This is the latest milestone on this project. Previously, we put in a place a mile-long southbound traffic switch, diverting traffic to the new lanes between River Road and SH 46.
