Following a more detailed cost-benefit analysis, the Texas Department of Transportation’s Bridge Division has determined to move forward with replacing the westbound bridge on I-40 at RM 2381 in Bushland rather than repairing the bridge, as originally planned. The analysis shows that the cost of rehabilitation exceeds the cost of replacement by nearly $2.5 million over the 75-year service life for each alternative presented.
The bridge was damaged in late February when a semitruck veered off the interstate, striking the bridge over RM 2381 before catching fire.
The project is scheduled to let in June 2017 with construction beginning in July.
“Our goal is to have the bridge and RM 2381 fully open within 45 to 50 days after we begin construction, provided there are no unforeseen issues,” says Blair Johnson, director of operations for the Amarillo District. “Traffic is traveling on beams that were not damaged during the fire, allowing us to keep the current traffic control plan in place until construction begins.”
As the construction date nears, TxDOT will provide updated traffic control plans and detour routes to the community and schools affected. Construction is anticipated to be completed in the fall due to an accelerated construction schedule designed to minimize the impact to both I-40 and RM 2381.
