The New Roosevelt Bridge in Stuart is a twin segmental box girder bridge
with over 560,000 square feet of bridge deck. This structure replaces two
aging bascule spans, the Northbound which opened in 1934 and the
Southbound in 1964. The older span, Northbound, is being removed and taken
out approximately seven miles offshore and dumped into the ocean to become
an artificial reef. The newer span, Southbound, is being retained for
local traffic and is scheduled for a complete rehab when the new bridge is
The project began in April, 1994. The project finished ahead of
schedule, and had an opening date of November 1, 1997.
With 1112 segments required for the project, it was necessary to cast
the segments in White City (15 miles North) and transport them to the
site. Due to the "S" configuration of the bridge, no two
segments are the same. This required careful monitoring and close
coordination with the contractor's reinforcing and post tensioning
A 546 foot long fishing pier was constructed at the water line under
the bridge connecting Flagler Park and the City Riverwalk. The fishing
pier utilizes the bridge footings as fishing platforms with benches,
lighting, and decorative railings.
The bridge has several unique features:
- Drainage of the bridge is completely contained inside the bridge via
fiberglass pipes where it is then piped to either end into retention
- The bridge was built using cantilever type construction with an
overhead gantry crane , which was necessary due to the shallowness of
the St. Lucie River. The gantry was approximately 430 feet long and 30
feet high which allowed it to complete two spans before having to be
- The interior is completely open which has allowed a golf cart to be
placed inside each bridge for ease of maintenance.
- A special class 5 concrete microsilica mix was used in the high
corrosion zone giving the bridge a 75 year lifespan.
