Parker County commissioners approved about $26,000 more for the Interstate 20 interchange project Monday to dispose of lead paint on the Old Brock Road Bridge.
The project, part of the Ric Williamson Memorial Highway, includes a new bridge and new ramp connections onto I-20.
Chris Bosco, of Freese & Nichols, told the court that the steel bridge beams and cross bracing had tested positive for lead paint in a study done by TxDOT.
He recommended Sunbelt Environmental be hired to dispose of it at each of the bridge beam cut locations, 20 on the main beams, 60 on the cross bracing.
The contract includes the disposal of two 55-gallon drums of hazardous waste.
Once it is approved by the Texas Hazardous Waste Commission the work will take five days to complete, Bosco said.
“This will occur at the same time they want to place the new beams on the bridge,” Bosco said. “They will set up a crane in the median, and traffic will be diverted onto the new ramps and frontage road so there won’t be any traffic under the bridge when they’re moving the beams or placing the new beams.”
The money will come from project contingencies, currently estimated at $628,577.
Bosco reported the estimated completion date for the new bridge to be early April 2014, the same as the contractual completion date.
“They’re looking to have all the frontage roads and ramps paved by the end of January,” he said. “That’s all triggered on them wanting to set the beams on Jan. 29. Whether they decide to remove the whole bridge or replace the beams, all that is going to happen in one week.”
