Nashville I-40 Fast Fix 8

Nashville, Tennessee

Dubbed the “Fast Fix 8,” the high-profile bridge rehabilitation project included removal and replacement of four twin bridges using Accelerated Bridge Construction (ABC) techniques. This stretch of I-40 in Nashville carries 140,000 vehicles daily. Pre-weekend work consisted of site access, over-excavation and backfill, soil nail retaining walls, mechanically stabilized earth retaining walls and bearing seat preparation.

Weekend work consisted of 58-hour closures of I-40 to remove and replace the bridge structures, including two bridges over CSX Railroad. Post-weekend work included installation of bridge overhangs, parapet, and site finishes.
The project was completed seven months early; a feat made possible through collaboration among all team members, extremely detailed schedules, tight controls, a robust quality program, continuity between preconstruction and construction and commitment to building work right the first time.
