Are you willing to put up with long road construction delays for better local roads?

Texas Department of Transportation will close alternating westbound lanes on Loop 410 between San Pedro Avenue and West Avenue from 9 p.m. to 5 a.m. Sunday through Friday nights, beginning the coming week. Three ramps have also been closed for long-term reconstruction.

Why it matters

The closures are part of the Loop 410 San Pedro Improvement Project, which realigns ramps and frontage roads around the Loop 410 and U.S. 281 interchange. Drivers in San Antonio who use this stretch should expect overnight delays and ramp detours until the work is complete.

The Loop 410 San Pedro Improvement Project carries a $156 million budget, and up to four westbound lanes may close at once between 9 p.m. and 5 a.m. The source does not say how long the nightly closures will run in total.

The players

Texas Department of Transportation

The state agency responsible for planning, building and maintaining Texas highways, including the Loop 410 San Pedro Improvement Project.

The details

Westbound Loop 410 lanes between San Pedro Avenue and West Avenue will close on an alternating basis, with at least one lane kept open at all times. Entrance and exit ramps may also close briefly, and the work is intended to realign ramps and frontage roads around the Loop 410 and U.S. 281 interchange; neither highway's main lanes will see major changes.

Nightly westbound lane closures begin the coming week, running from 9 p.m. to 5 a.m. Sunday through Friday.
Honeysuckle Lane exit ramp from westbound Loop 410 is expected to reopen in summer 2027.
NW Military Highway exit ramp from westbound Loop 410 is expected to reopen by the end of 2027.
Blanco Road entrance ramp onto eastbound Loop 410 is expected to reopen in spring 2028.
The full Loop 410 San Pedro Improvement Project is expected to be complete by the end of 2029.

Roadmap

This phase is one step in the multi-year Loop 410 San Pedro Improvement Project, which reshapes the Loop 410 and U.S. 281 interchange in San Antonio. Ramp reopenings are staged from summer 2027 through spring 2028, with full completion expected by the end of 2029.

Drivers on westbound Loop 410 between San Pedro Avenue and West Avenue should plan for lane closures from 9 p.m. to 5 a.m. Sunday through Friday, and for the closed ramps to NW Military Highway, Honeysuckle Lane and Blanco Road, which will stay out of service for months or years.

The takeaway

Plan nighttime commutes on westbound Loop 410 around the 9 p.m. to 5 a.m. closure window, and identify alternate routes for the ramps that will stay closed into 2028 and 2029.

What happens next

Honeysuckle Lane exit ramp reopens in summer 2027, NW Military Highway exit ramp by the end of 2027, and Blanco Road entrance ramp in spring 2028, with full project completion by the end of 2029.
