Demolition of the Parker Road bridge at U.S. 75 closed down the interstate for four nights in late summer in Collin County. TxDOT says all work was cleaned up and moved out of the way before the rush hour traffic each morning on Central Expressway.

To accomplish this, TxDOT and Houston-based W.W. Webber LLC demolition crews tore down most of the concrete pavement of the old Parker Road bridge over southbound U.S. 75 mainlanes. The remainder of that section, including pavement and support beams, were removed another evening.

Crews completed the demolition over four nights.

The work 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 estimated project completion is fall 2010.
