Lane closures are in effect along one of Downtown Round Rock’s most heavily traveled corridors as the City continues work on the Mays Street Bridge Wall Stabilization Project.

The long-planned infrastructure effort addresses settlement and movement of retaining walls at the south end of the historic Mays Street bridge over the railroad. Work below the bridge began in fall 2025, and the project has now progressed to improvements on top of the bridge and roadway approach. Lane closures will vary throughout construction, but one lane of traffic in each direction is expected to remain open at all times. Sidewalk access may also be limited at times, with one sidewalk anticipated to be kept open when feasible.

City Council unanimously approved the construction contract for the project on June 12, 2025, awarding the work to Austin Filter Systems. The contract total was just over $2 million and is funded through Type B sales tax revenue. Construction is expected to be completed in late spring 2026.

The project is designed to address decades of gradual settlement along the south abutment by reinforcing the retaining walls and bridge approach. The first phase focused on strengthening the base of the walls using ground anchors and related structural elements to address the root causes of the movement. With that work complete, crews have moved on top of the bridge and approach for the next phase of repairs, which includes reconstructing the most impacted section of retaining wall near the bridge, installing structural tie elements to lock both sides of the wall system together, replacing portions of the roadway approach and sidewalks, and completing rail painting as part of the overall rehabilitation work.

The Mays Street bridge is known as the Immortal Ten Bridge in remembrance of the Jan. 22, 1927 train-bus crash in Downtown Round Rock that killed 10 people connected to Baylor University who were traveling to Austin for a game — a tragedy Baylor honors as the “Immortal Ten.” On the 90th anniversary of the crash, the City and Baylor representatives formally dedicated the bridge as the Immortal Ten Bridge, and the City anticipates honoring the tragic event again for its 100th anniversary in 2027.
