John T. Collinson Bridge

The 11,658’ long John T. Collinson Bridge is the first use of precast segmental technology for heavy rail in North America. It carries the rail line over Escambia Bay en route from Jacksonville to New Orleans. The bridge has 100’ spans that rise on a 1% grade to a three-span continuous main span unit, which provides 50’ vertical clearance over the navigation channel. The bridge was designed to endure hurricane force winds as it successfully did so in 2004 and 2005 with Category 3 hurricanes Ivan and Dennis.
