I-24 Southeast Choice Lanes
Nashville, TN, USA | TDOT - 2024–Present | DBFOM
Project Description
The I-24 Southeast Choice Lanes Project is a major transportation initiative designed to improve mobility and reliability along the I-24 corridor in the Nashville metropolitan area. The project will implement managed Choice Lanes along approximately 26 miles of Interstate 24, extending from downtown Nashville to the Murfreesboro area, one of the most heavily traveled commuter corridors in Middle Tennessee.
The project includes new managed lanes, interchange improvements, bridge modifications, and corridor-wide operational enhancements, aimed at improving travel reliability, reducing congestion, and supporting long-term regional growth.
The improvements are part of Tennessee’s Choice Lanes Program, which introduces managed lanes to key corridors in the state to improve travel reliability while maintaining free-flowing general-purpose lanes.

Magnitvde supports Meridiam and the broader developer consortium by providing technical, construction, and project management advisory services during the development and proposal phases of the project.
Our role includes coordinating design development between the SPV, DBJV, and designers, guiding the identification and refinement of Alternative Technical Concepts (ATCs), and advising on design optimization, constructability, and delivery strategy.
Magnitvde also advises the SPV on construction planning and project delivery, including the evaluation of construction costs (CAPEX), schedules, staging strategies, and construction sequencing, while supporting the identification and management of key technical, construction, and delivery risks.
In addition, Magnitvde provides strategic input to the technical proposal development, ensuring consistency across design, construction, quality, and risk narratives and alignment with RFP requirements and consortium strategy.
