Bad news: I-10, Loop 1604 interchange closed on NW Side this weekend. Good news: It’s the last closure of the year!

Closures will allow crews to install steel beams, continue construction of flyover ramps at the interchange

Traffic alert (KPRC 2)

SAN ANTONIO – TxDOT is giving San Antonio drivers a holiday treat by giving them a break from weekend closures at the Loop 1604 and Interstate 10 interchange on the Northwest Side.

From Nov. 27 through Dec. 31, TxDOT has no plans to schedule major weekend construction closures at the busy intersection, which is a relief for holiday shoppers at La Cantera and The Rim.

The closures will allow crews to install steel beams and continue the construction of the flyover ramps at the interchange. Steel beam work is currently 80% complete with 120 beams in place. The first flyover ramp is scheduled to open by the end of the year, connecting drivers from eastbound Loop 1604 to westbound I-10.

Access to businesses will remain open during construction and law enforcement officers will help with traffic flow at intersections. Closures may open early if work is completed and the road is safe for drivers, TxDOT said.
