News Summary
San Antonio’s traffic will be significantly affected over the weekend due to major road closures announced by TxDOT for construction on Loop 1604 at the I-10 interchange. The closures will begin on Friday and last through Monday morning, impacting various lanes. In addition, utility repairs on Loop 1604 may cause further disruptions. These construction efforts are part of a larger $1.4 billion project to expand Loop 1604 to improve traffic flow and safety.
San Antonio – Major road closures are set to impact traffic in the San Antonio area as the Texas Department of Transportation (TxDOT) progresses on significant construction projects this weekend, while Culebra Road reopened after an earlier incident involving an 18-wheeler.
TxDOT has announced that closures on Loop 1604 at the Interstate 10 interchange will begin on Friday, May 16, at 9 a.m., and continue until 5 a.m. on Monday, May 19. These closures are necessary to facilitate the construction of flyover ramps integral to the interchange improvement project.
During this period, all lanes of U.S. 281 and the westbound lanes of Loop 1604 will be shut down at the U.S. 281 and Loop 1604 interchange from 9 p.m. on Friday through 5 a.m. on Monday. Additionally, the eastbound lanes of Loop 1604 will also experience nightly closures from 9 p.m. to 5 a.m. over the same weekend.
Frontage roads in both directions along Loop 1604 will also be closed during the weekend. Drivers are advised to use alternative routes and follow traffic diversions that have been established to ease the impact of the closures on access to Loop 1604 and I-10.
For ongoing construction, daily closures will affect Loop 1604 eastbound and westbound from 5 a.m. to 9 p.m., with nightly closures from 9 p.m. to 5 a.m. This construction initiative is currently 62% complete, and the next flyover ramp is anticipated to open by early summer.
Recent Incident on Culebra Road
Earlier today, the Bexar County Sheriff’s Office successfully cleared a road closure on Culebra Road, which had been halted due to an 18-wheeler that became stuck near 10:30 a.m. Both east and westbound lanes of the road were initially shut down as officials worked to resolve the traffic hazard. The lanes have since reopened, and normal traffic flow has resumed.
Utility Repairs and Their Effects
In a separate issue, utility workers are addressing a damaged water main on Loop 1604 caused by a fiber-optic drilling contractor. San Antonio Water System (SAWS) is overseeing the repair of the 24-inch water main, with completion expected by May 20. This damage may also contribute to traffic disruptions in the area as repair efforts continue.
Context of Construction Projects
The road closures are part of the $1.4 billion Loop 1604 North Expansion Project, which aims to expand Loop 1604 from four to ten lanes. This effort is intended to improve traffic flow and safety for the increasing number of vehicles using the roadway. As the project progresses, TxDOT has committed to providing timely updates to the public to minimize inconveniences.
Residents and commuters are encouraged to stay informed about traffic conditions and to plan their routes accordingly in light of the construction activities and road closures. TxDOT and local authorities are working diligently to ensure that traffic impacts are minimized as much as possible.
