Roosevelt Bridge, Bascule bridge in Stuart, Florida

Roosevelt Bridge is a high-level segmental bridge carrying U.S. Route 1 across the St. Lucie River in Stuart, Florida. Completed in 1996, it is about one mile long and made of two parallel three-lane spans, with a flat deck on evenly spaced concrete piers set low over the water. The older twin drawbridges remain downstream as Dixie Highway (County Road 707).

The first Roosevelt Bridge opened in 1934 as a northbound drawbridge; a parallel southbound drawbridge followed in 1964. Both were replaced by the current high-level bridge, completed in 1996, which carries U.S. Route 1 on two parallel three-lane spans. The 1964 southbound drawbridge remains in use for road and boat traffic as part of Dixie Highway (County Road 707).

The bridge shapes Stuart's streetscape and links two riverbanks while allowing boats to pass through. Visitors often watch the central span lift to let taller vessels navigate the waterway.

Visitors can cross the bridge on foot or by car and watch the river from both banks. It is best to visit during daylight hours when views are clear and water activity is visible.

The southbound span stayed fully closed until November 5, 2020, after inspectors found severe corrosion and ruptured steel tendons. During the closure, tolls were waived on Florida's Turnpike between Stuart and Port St. Lucie, and both spans later received a new topcoat sealant against water seepage.
