I-24/Marine Drive Extension
Marine Drive from Cowan Street to Dickerson Pike under I-24 and the replacement of the I-24 Bridge over Marine Drive
This website is under development.
History and Background
TDOT will help provide the greater East Nashville community with a multimodal connectivity to the River North section of the East Bank Development and the planned Oracle campus. Such connectivity will be provided by extending the Marine Drive from Cowan Street to Dickerson Pike (State Route 11, US-41). This project also includes the replacement of the Interstate 24 bridge over the extension and the realignment of Dickerson Pike.
TDOT is implementing an alternative delivery Design-Build (DB) model to deliver this project. Once a DB team is selected, design and construction activities may overlap, allowing construction to start sooner than traditional methods.
Current Status: TDOT is seeking Request for Proposals (RFP)
Estimated Construction Start & Completion: See table.
