The existing two-lane 2,100-foot (ft) long Bridge, constructed in 1963 and includes a double bascule over the Intracoastal Waterway (ICWW) main waterway channel, is to be replaced due to structural deficiencies. The existing bridge includes two 10-ft 10-inch lanes, two 4-ft shoulders, and a 5-ft raised sidewalk on the north side. There are no dedicated bicycle lanes or barriers between vehicles and pedestrians.
The bridge will be replaced with a high-level 4,152.5-ft long fixed bridge crossing over the FEC Railroad, Old Dixie Highway, and the ICWW. The new bridge will have 85 feet of vertical clearance (↕) and 125 feet of horizontal clearance (↔) at the main waterway channel. 7-ft buffered bicycle lanes will be provided within the 8-ft shoulders on either side of the two 12-ft travel lanes. An 8-ft barrier protected sidewalk will be provided on the south side of the bridge. A 10-ft barrier protected, buffered shared-use path will be provided on the north side. The project also includes improvements to Old Dixie Highway and extensions of Juanita Avenue and Sunny Lane between US 1 and Old Dixie Highway.
The North Causeway Bridge Replacement project has been approved by the Florida Department of Transportation (FDOT). FDOT granted Location and Design Concept Acceptance (LDCA) for the Project Development and Environment (PD&E) Study prepared for the bridge project on November 15, 2018.
