Background
The Loop 1604 North Expansion is a Texas Clear Lanes project aimed at enhancing safety, improving mobility and reducing congestion along 23 miles of Loop 1604 from SH 16 (Bandera Rd.) to I-35. This $1.4 billion project includes the expansion of mainlanes from a 4- to 10-lane expressway, high-occupancy vehicles (HOV) lanes in each direction, a multi-level interchange at I-10, an innovative intersection at Blanco Road, and bicycle and pedestrian accommodations on the frontage roads.
The 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 complete in 2025.
- Segment 2, the Loop 1604 and I-10 interchange, is on schedule to be complete by 2027. The first flyover ramp opened December 2024 and a second ramp is on schedule to open summer 2025.
- Segment 3, from I-10 to US 281, is on schedule to be complete by early 2026.
- Segment 4, from US 281 to Redland Road, is on schedule to be complete by 2027.
- Segment 5, from Redland Road to Judson Road, began construction spring 2025.
