Demolition work on Lewisville’s Main Street bridge is scheduled to begin Sept. 6 at 9 p.m. and continue through Sept. 7 at 11 a.m.

All lanes will be opened back up at that time, but will then close again that evening at 9 p.m. before reopening Sept. 8 at 11 a.m., according to a city news release. This comes on the heels of a project combining the Main Street and Fox exits off I-35E, which was completed Aug. 26.

The work is part of a $105 million project that reconstructs the FM 1171 bridge over I-35E, reconstructs 1.3 miles of the main interstate lanes and constructs a new northbound frontage road from Fox Avenue to College Street, Tila Grant, public information officer for the Texas Department of Transportation, told Community Impact.

Early this summer, crews reconfigured traffic lanes by shortening the westbound turn lane onto the I-35 frontage road. The project began in 2023 and is projected to be completed in fall 2026.

The details


Once the existing bridge is demolished, there will only be two lanes of traffic in each direction. Traffic headed northbound on I-35E will be required to take Exit 451, according to the release. The lane closure needed for this traffic detour will start near Corporate Drive.

Northbound I-35E entrance ramps starting near Corporate Drive will be closed, including the ramps coming from Corporate Drive, Business 121 and Fox Ave. Police officers will be at the Business 121 and Main Street intersections to assist with traffic control.

Traffic heading southbound on I-35E will need to take Exit 452. The lane closures will start north of Justin Road, and the entrance ramp from Justin Road will be closed.

Also of note


The project is part of a larger Denton County Connections initiative and the Texas Clear Lanes project aimed at mitigating traffic bottlenecks caused by rapid population and industry growth along the I-35 corridor, according to documents.

Texas Clear Lanes is a statewide strategic plan to provide congestion relief through nontolled roads and is focused on the five largest metro areas in the state.
