I-4/St. Johns River Design-Build Bridge Replacement

The I-4 St. Johns River Bridge Design-Build project required construction of parallel high level bridges over the St. John's River just north of Orlando, Florida. The project included construction of two, three-lane Florida Bulb T-Girder bridges over the St. John's River, as well as demolition and removal of the existing river bridge, originally built in 1964. Each of the new bridges are 2,600 feet in length and have a maximum vertical clearance of 45 feet in the navigation channel.  The Florida Bulb-T superstructure is founded on concrete piling with cast-in-place footings, columns and caps.

This project involved the replacement of the existing 4-lane bridge with two new 3-lane high level bridges. The original bridge had the highest volume of traffic per lane in central Florida, at the time, and traffic had to remain uninterrupted during construction.

PCL self preformed all elements of construction from pile installation through deck placement. By self performing all major components of work, PCL was able to save 4 months on the construction of the new bridges.
