TxDOT: Weekend road closures focus on rebuilding of interchange on Northwest Side

SAN ANTONIO (KTSA News) — Major closures will effect travel this weekend at the junction of Loop 1604 and Interstate-10.

As part of the Loop 1604 North Expansion project, TxDOT is scheduled to fully close the interchange of Loop 1604 and I-10 in northwest San Antonio for this weekend.

The weekend closures are scheduled to begin at 9 p.m. on Friday, January 26 and are expected to be completed by 5 a.m. on Monday, January 29, weather permitting. Closures at the interchange will include:

• I-10 eastbound/westbound mainlanes from UTSA Blvd. to La Cantera Parkway

CPS Energy is working to improve the quality of aging overhead electrical lines on the northwest sector at the intersection of IH 10 Frontage Rd and Heuermann Rd.

• The IH 10 project will involve removing and installing a new overhead primary line across IH 10 Frontage Road and Heuermann Road and requiring rolling traffic stops. The work will take place on Sunday, January 28, 2024, from 6:00 a.m. – 4:00 p.m., weather permitting.

 CPS Energy contractor crews will be working on the above project, which will cause two scheduled outages affecting two business customers who have been informed.

 OSO will provide traffic control on the East and West bound sides of IH10 resulting in nine rolling traffic stops lasting up to 15 minutes.
