Additionally, the I-10 WB frontage road lanes between Loop 1604 WB frontage road and the La Cantera Parkway exit ramp will be closed on the weekend nights only.

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.
