JACKSONVILLE, Fla. – The Main Street Bridge will be closed nightly from 6:30 p.m. until 6 a.m. Friday, with the exclusion of Wednesday, when the closure will begin at 9 p.m., according to the Florida Department of Transportation. The bridge will then be closed from 6:30 p.m. Friday through Sunday at 6 a.m.
Both vehicular and pedestrian traffic will be detoured to the Acosta Bridge. Signs will direct traffic through the detour. Boaters will not be impacted by the closures.
The closures are necessary to install and test temporary mechanical systems as part of the ongoing improvement project. These closures are unrelated to the cruise ship that struck the bridge Friday night.
The improvements to the Main Street Bridge include the replacement of several major mechanical components, replacement of the entire electrical control system, replacement of the traffic gates, sidewalk gates, lighting protection system, and closed-circuit television cameras that give operators live views of traffic conditions. The work will include new heating and air conditioning units, water and sanitary sewer lines, and floor tile for the control house.
M&J Construction of Tarpon Springs was awarded the $10.7 million contract. The project is expected to be completed by spring.
The Main Street Bridge is a vertical lift bridge and is raised and lowered approximately 1,400 times a year.
