SAN ANTONIO – It’s another round of major closures on the far Northwest Side as the Texas Department of Transportation will once again close Loop 1604 and parts of Interstate 10 this weekend to continue construction on the Loop 1604 North Expansion Project.
TxDOT will have a full closure of the Loop 1604 east and westbound main lanes at the I-10 interchange starting at 9 p.m. on Friday, May 3, until 5 a.m. on Monday, May 6, weather permitting.
Three of four cloverleaf ramps at the Loop 1604 and I-10 interchange will also be shut down. The westbound main lanes of I-10 will also be closed, but the eastbound main lanes of I-10 at the interchange will remain open. Another change is eastbound 1604 traffic will be closed to Lockhill Selma Road.
This is a full closure and lanes are expected to remain closed for the entire duration of the weekend. Crews are installing steel beams for a second flyover ramp.
Local law enforcement will direct traffic through the intersections during this time. Drivers are encouraged to plan an alternate route and avoid the area, if possible. Below is a map and detour information.

All travelers on the I-10 WB main lanes and those looking to access Loop 1604 WB 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 either re-enter the IH-10 WB main lanes at the first entrance ramp after the Loop 1604 interchange or utilize the U-turn at La Cantera Parkway to access Loop 1604 WB.
