COLLIN COUNTY - After an initial rain delay, the Texas Department of Transportation announced it has completed demolition of the first Parker Road bridge span, which required closure Tuesday night of the northbound U.S. Highway 75 mainlanes.

Demolition was to continue Wednesday night and continue each day from 10:30 p.m.-6 a.m. the next day through Saturday morning.

The northbound frontage road was slated for Wednesday night, with the southbound mainlanes set for tonight and the southbound frontage road set for Friday night. The nightly closures are necessary to ensure the safety of the traveling public, as well as the contractor, while the demolition takes place, officials said.

The demolition is part of a $20 million construction project to convert the U.S. 75 and Parker Road interchange from a standard, grade-separated bridge to a single-point urban interchange. The project is set for completion in the fall 2010.

Message boards have notified the public of the closures and law enforcement is present for traffic control.

The estimated project completion is fall 2010. TxDOT and W.W. Webber, LLC would like to thank area drivers, local businesses, the City of Plano, and Collin County for their continued patience and cooperation as crews work diligently to complete this project as soon, and as safely, as possible.
