The original St. Johns River Bridge was a four-lane concrete-and-steel causeway bridge constructed over the St. Johns River at the west outlet of Lake Monroe.

It is a part of Interstate 4, and spans the border between Seminole and Volusia Counties in Florida, United States.

The bridge's design, which lacked shoulders for disabled or wrecked vehicles to pull out of the flow of traffic, made it a severe bottleneck for commuters going to the Orlando Area beginning in the 1980s.

Work began in 2001, and a new dual structure consisting of two three-lane spans, each with wide shoulders on either side, was fully opened in May 2004.

Upon completion, the new structure was officially renamed the St. Johns River Veterans Memorial Bridge.
