The Texas Department of Transportation (TxDOT) has announced plans to close all lanes of Interstate 35 between Corporate Drive and Roy Richard Drive in Schertz, as well as reroute the eastbound lanes of Loop 1604 between Nacogdoches Road and Ikea-RBFCU Parkway, over the upcoming weekend. These closures are part of TxDOT's $3 billion I-35 NEX project to expand the interstate from 8 to 14 lanes along San Antonio's Northeast Side.

Why it matters

The planned closures will cause significant traffic disruptions and delays for drivers in the Northeast San Antonio area, as the I-35 and Loop 1604 corridors are major thoroughfares. The construction work is necessary to support TxDOT's multi-year project to expand and improve the interstate system in this rapidly growing part of the city.

The details

The I-35 closure will be in effect from 8 p.m. on Friday, February 13 to 7 a.m. on Saturday, February 14, while the Loop 1604 eastbound lane reroute will be in place from 8 p.m. on Saturday, February 14 to 7 a.m. on Sunday, February 15. TxDOT says the closures are needed to allow construction crews to perform concrete deck work as part of the I-35 NEX project, which is expanding the interstate from 8 to 14 lanes.
