BRIDGE CONSTRUCTION: TDOT using ABC methods on I-24 bridges in Nashville

June 23, 2017

The heavily traveled bridges will be replaced within months instead of years

The Tennessee Department of Transportation (TDOT) plans to use accelerated bridge construction (ABC) techniques for replacing I-24 bridges in downtown Nashville.

More than 148,000 vehicles travel on this section of I-24 daily. The $28.5 million project will include replacement of the bridges over Oldham Street and Spring Street on the eastern loop of downtown, deck repairs to the Silliman Evans Bridge and resurfacing of the entire area.

TDOT reports that the bridges over Oldham and Spring streets are in advanced stages of deterioration that requires immediate attention. For the ABC work, crews will work non-stop during the closures, when they will remove the old bridge superstructures, place new components, pour fast-curing concrete, and add barriers and striping.

The department says the work will require complete closure of I-24 from the I-40 split east of downtown Nashville to the I-65 split north of the city for at least four weekends starting this fall. The construction work is expected to be complete by June 2018.
