 WHAT TO EXPECT
As part of the Loop 1604 North Expansion project, TxDOT has planned a closure of the eastbound and westbound mainlanes of I-10 at the Loop 1604 interchange. The mainlanes of Loop 1604 will remain open. This closure will allow crews to continue construction of the flyover ramps at the interchange.
The closures are scheduled to begin at 9 p.m. on Friday, June 14, and are expected to be completed by 5 a.m. on Monday, June 17, weather permitting. During this time, local law enforcement will direct traffic through the intersections including the intersection of I-10 and La Cantera Parkway.
Access to businesses around the interchange will remain open. Detour information for traffic through the closures is listed below.
Additional closures will continue at the Loop 1604 and I-10 interchange to allow crews to install steel beams for the construction of the flyover ramps. Detailed closure information will be shared each week as the work is confirmed.
Major construction closures will not be scheduled during the 4th of July holiday.
Please note, construction schedules are subject to change and weather permitting.

MORE ABOUT THE PROJECT
This work is part 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.
This project brings $1.4 billion of transportation investments including the expansion of mainlanes from a 4- to 10-lane expressway, high-occupancy vehicles (HOV) lanes in each direction, a multi-level interchange at the I-10 intersection, an innovative intersection at Blanco Rd., and bicycle and pedestrian accommodations on the frontage roads.
The Loop 1604 North Expansion is planned in six segments with four segments currently under construction. Segment 1, from SH 16 to I-10, is on schedule to be completed and open to traffic by early 2025. Segment 2, the Loop 1604 and I-10 interchange, is on schedule to be completed by 2027 with the first flyover ramp opening by the end of 2024. Segment 3, from I-10 to US 281, is on schedule to be completed by the end of 2025. Segment 4, from US 281 to Redland Rd., began construction April 2024.
Note: All closures are weather permitting and subject to change.
