JACKSONVILLE, Fla. – The Main Street Bridge (State Road 5) will reopen at noon on Friday after a weeklong bridge inspection and maintenance project that closed the bridge to pedestrians, drivers and cyclists.
The work was part of a larger rehabilitation effort to evaluate the bridge’s mechanical systems and structural health.

Crews conducted a LiDAR (Laser Imaging, Detection, and Ranging) scan, along with a full mechanical inspection of the bridge’s lift system. This includes the trunnion bearings — large pivot points that act like the bridge’s “shoulder joints,” allowing it to open and close for vessel traffic.
“These parts wear down over time,” FDOT said in a statement, “and the data collected this week will help engineers plan a major trunnion replacement scheduled for early 2028.”
Vessels traveling beneath the Main Street Bridge were not impacted by the closure.
