The Tennessee Department of Transportation has officially started a major construction project to replace four I-40 bridges over 8th Avenue in Nashville. These structures reached the end of their service life and have begun to show significant signs of deterioration.
Why it matters
Replacing these aging bridges is critical to maintaining the structural integrity of the interstate system serving Nashville. The project ensures long-term safety for drivers while modernizing essential infrastructure that handles high volumes of daily traffic.
The project covers four bridges on I-40 and utilizes Accelerated Bridge Construction techniques to minimize site impact. Each work zone extends 150 feet beyond the bridges to facilitate necessary substructure repairs.
The players
Tennessee Department of Transportation
This state agency is responsible for the planning, implementation, and maintenance of Tennessee's roadway and bridge infrastructure.
Bell & Associates
This company is the primary construction contractor tasked with executing the bridge replacement project on behalf of the state.
The details
Bell & Associates is serving as the contractor using the Construction Manager/General Contractor delivery method. The project requires nightly lane closures on I-40 between 9:00pm and 5:00am, alongside restriping on 8th Avenue to maintain a continuous southbound lane.
Timeline
Construction officially began in September 2026.
Substructure work is estimated to be complete by fall 2027.
Two weekend closures are planned for October 2027.
A third weekend closure is scheduled for April 2028.
Substantial completion of the project is expected in summer 2028.
Market Landscape
The project follows the safety protocols established by the Tennessee Move Over Law, which mandates severe penalties of up to 30 days in jail and a $500 fine for non-compliance. This construction effort mirrors broader state trends toward modernizing aging transit assets.
Commuters should anticipate nightly lane closures on I-40 and potential traffic shifts on 8th Avenue throughout the project duration. Drivers are reminded to observe safety laws near work zones to avoid the state-mandated fines and potential jail time.
The takeaway
Motorists should prepare for long-term construction impacts by planning alternative routes during the scheduled 2027 and 2028 weekend closures. Adhering to posted speeds and move-over regulations remains essential to navigating this multi-year infrastructure update safely.
What happens next
The Tennessee Department of Transportation has scheduled two weekend closures for October 2027 and a third closure for April 2028 to accommodate the bridge replacement work.
