TxDOT shutting down major Northwest Side freeways for interchange work again this weekend

SAN ANTONIO (KTSA News) — The Texas Department of Transportation is closing Loop 1604 and I-10 at 9 p.m.  Friday evening and reopening Monday morning at 5 a.m. as work continues on building a new interchange of the two roads.

Closures at the interchange will include:

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