Memorial Bridge, Four-lane concrete bridge in Palatka, Florida.

Memorial Bridge is a four-lane bridge, 4,020 ft long with 65 ft of vertical clearance, carrying US 17 and SR 100 over the St. Johns River between Palatka and East Palatka. Goodwin Riverfront Park sits at its west end and Veterans Memorial Park at its east end.

The first bridge here was built in 1888 by the Palatka Bridge Company for rail-operated vehicles. A concrete bridge carrying two lanes of vehicular traffic was completed in 1927. The current four-lane span, completed in 1976, is 4,020 ft long and continues to commemorate Putnam County's military personnel.

The bridge's name and its four bronze Doughboy statues, two at each side, commemorate the men and women of Putnam County who served in the military. The figures once guarded the earlier drawbridge and were kept at the foot of the current span, so the memorial function carried over from one bridge to the next.

The bridge deck sits 65 ft (20 m) above the St. Johns River, so sailboats and barges pass beneath without an opening span. Goodwin Riverfront Park on the Palatka side and Veterans Memorial Park in East Palatka sit at the two ends, giving a place to stop before or after crossing. US 17 and SR 100 share the four-lane deck.

This is the only permanent vehicle crossing of the St. Johns River between Green Cove Springs and Astor, making it a critical connection point for the entire region. Many travelers do not realize how essential this single bridge is for local traffic flow.
