Interstate 10, Loop 1604 will be closed starting Friday night, reopening at 5 a.m. on Jan. 15

The Texas Department of Transportation will close the Loop 1604 and Interstate 10 interchange in San Antonio starting Friday night and re-opening at 5 a.m. on Monday. Yes, that’s right, a full freeway closure. 

So, if you’re heading to Target or Bass Pro Shops, consider alternative routes because this is messy. 

“This work is part of Segment 2 of the Loop 1604 North Expansion – a Texas Clear Lanes project aimed at improving mobility and reducing congestion along 23 miles of Loop 1604 from SH 16 (Bandera Rd.) to I-35,” TxDOT wrote in an email. “Segment 2 includes $418 million of investments to expand the main lanes from a 4- to 10-lane expressway, add high-occupancy vehicle (HOV) lanes in each direction, and construct an innovative and multi-level interchange at the I-10 intersection. Construction began later in the summer of 2022, with completion by 2027.”

As part of the Loop 1604 North Expansion Project, TXDOT will require the following closures for bridge construction. 

• The I-10 eastbound (EB) main lanes through the Loop 1604 interchange;
• I-10 westbound (WB) main lanes through the Loop 1604 interchange;
• The Loop 1604 EB main lanes through the I-10 interchange;
• The Loop 1604 WB main lanes through the I-10 interchange;
• The Loop 1604 EB frontage road between the I-10 EB and WB frontage roads;
• Finally, the Loop 1604 WB frontage road will be closed between the IH-10 WB and EB frontage roads. 

Of course, all of this construction is already underway as TxDOT completes its massive building project to improve congestion on 1604. The agency offers these detours: 

I-10 EB main lanes

• Travelers on the I-10 EB main lanes looking to continue through the Loop 1604 interchange will exit to the I-10 EB frontage road after La Cantera Parkway and follow the IH-10 EB frontage road through the interchange. Travelers will re-enter the I-10 EB main lanes at the first entrance ramp after the Loop 1604 interchange.

I-10 WB main lanes

• Travelers on the IH-10 WB main lanes looking to continue through the Loop 1604 interchange will exit to the IH-10 WB frontage road after UTSA Boulevard and follow the IH-10 WB frontage road through the interchange. Travelers will re-enter the IH-10 WB main lanes at the first entrance ramp after the Loop 1604 interchange.

Loop 1604 EB main lanes and frontage road

• Travelers on the Loop 1604 EB main lanes looking to continue through the IH-10 interchange will exit at the Vance Jackson Road exit ramp to enter the Loop 1604 EB frontage road. Travelers will follow the signs for IH-10 EB and continue on the IH-10 EB frontage road to the U-turn at UTSA Boulevard. Travelers will follow the IH-10 WB frontage road back to the Loop 1604 EB frontage road, entering the Loop 1604 EB main lanes at Vance Jackson Road.

Loop 1604 WB main lanes and frontage road

• Travelers on the Loop 1604 WB main lanes looking to continue through the IH-10 interchange will exit at the IH-10 exit ramp to enter the Loop 1604 WB frontage road. Travelers will follow the signs for IH-10 WB and continue on the IH-10 WB frontage road to the U-turn at La Cantera Parkway. Travelers will follow the IH-10 EB frontage road back to the Loop 1604 WB frontage road, entering the Loop 1604 WB main lanes after Valero Way.
