Long-Term Northbound I-35 Watson Lane Exit Ramp Closure

The northbound Interstate 35 (I-35) Watson Lane exit ramp will close long-term beginning 9 p.m. Saturday, August 1. Scheduled to reopen Summer 2021, the closure will continue our phasing for construction of the new Parkway intersection. The intersection will add dedicated turnarounds to the frontage roads between Kohlenberg Road/Conrads Lane and Watson Lane.

During this time, traffic will be detoured to the northbound I-35 Kohlenberg Road/Conrads Lane exit ramp before the Watson Lane exit ramp.

Switching Things Up: Next Milestone On Loop 337 Project in New Braunfels

Following rush hour tomorrow (Saturday, Dec. 21) morning, the newly constructed southbound Loop 337 lanes between New Braunfels High School (north of the SH 46 overpass) and just south of Oak Run Parkway will open to drivers as the latest in a series of scheduled traffic switches on the Loop 337 Expansion Project.

All southbound traffic will be permanently shifted to the new lanes. Once this section has opened, crews will begin work on existing lanes, with one northbound lane remaining open to traffic.

Following the traffic switch, drivers turning from Oak Run Parkway will only be able to head southbound on Loop 337. Drivers wishing to head north on Loop 337 will need to take southbound Loop 337 and turn around at Stone Crossing.

This section of southbound Loop 337 is the last to open as part of this project. Crews will continue working on sections of northbound Loop 337 and making additional improvements in future phases of this project.

Message signs are in place to inform drivers of this change and additional signage will be placed to help guide drivers safely along the roadway.

We ask the traveling public to follow construction signage and remain alert when traveling through the work zone. 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 estimated to be completed in late 2021. The construction project is about six miles long, from I-35 to Hillcrest Drive, and includes an upgrade to a 4-lane divided roadway with pedestrian accommodations and new bridges in various locations.

Loop 337 Expansion: Traffic Switch & New Exit Ramp

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.

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.
