Summer relief for drivers on the Loop 1604 North Expansion

TxDOT is providing relief to drivers this summer by shifting the construction schedule at the Loop 1604 and I-10 interchange to minimize traffic impacts on the busy corridor. From now through Labor Day weekend, the new schedule allows for six weekends with minor or no closures at the interchange.

For the past several months, work has been focused on lifting and setting steel beams as crews construct flyover ramps at the interchange. Steel beam work is currently 50% complete with 75 beams in place. Later this year, the first flyover ramp is scheduled to open, connecting drivers from eastbound Loop 1604 to westbound I-10.

The following summer schedule of weekend construction at the Loop 1604 and I-10 interchange includes the minimum number of closures required to maintain project momentum.

3 weekends with no closures
All lanes will be open.

- July 4 through July 8
- August 9 through August 12
- August 30 through September 2

3 weekends with minor closures
Some lanes and ramps will be closed. One highway may be closed in a single direction (e.g. eastbound Loop 1604).

- July 12 through July 15 *updated 7/8/24*
- July 26 through July 29
- August 2 through August 5

4 weekends with major closures
One highway will be closed in both directions (e.g. eastbound and westbound Loop 1604). Ramps may be closed.

- June 28 through July 1
- July 19 through July 22 *updated 7/8/24*
- August 16 through August 19
- August 23 through August 26

TxDOT is committed to scheduling closures that create the least impact to traffic and allow work to be completed safely.

Drivers are encouraged to consider the construction schedule as they plan summer activities and keep this important information in mind:

• Weekends closures begin at 9 p.m. on Fridays and end at 5 a.m. on Mondays.
• Access to businesses remain open during construction.
• Law enforcement officers will assist with traffic flow at intersections.
• Closures may open early if work is completed, and the road is safe for drivers.
• Detailed closure information will be shared each week as the work is confirmed.
• Visit www.DriveTexas.org for the latest information on closures and road conditions.

All construction lane closures are weather permitting and subject to change. Stay connected on TxDOT San Antonio’s X feed, @TxDOTSanAntonio, and Facebook page, @TxDOTSanAntonioTX, for ongoing construction and traffic updates.

Background
The Loop 1604 North Expansion is 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 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.
