I-40 Over 8th Avenue Bridges

History and Background

Every two years, TDOT performs a comprehensive inspection and subsequent evaluation of all public bridges across the state in order to determine the status of their working condition and operating limits. These inspections and evaluations are to ensure that bridges are in accordance with the Federal Highway Administration (FHWA) National Bridge Inspection Standards (NBIS). The proposed project is needed to address the various structural deficiencies for each of the four bridges, as described by the TDOT Engineering Division, Structures Section, and in the most recently available inspection reports.

TDOT will be using an Alternative Delivery: Construction Manager/General Contractor (CM/GC) method for this bridge replacement project. This delivery method involves a contractor in the design phase to mitigate risk, improve the construction schedule, and streamline the design process.
