Johnson Bayou Crossing

Technical Description:

• Span: 28 ft
• Rise: 7 ft
• Length: 42 ft

This project for the Florida DOT in an extremely aggressive salt water environment exposed to hurricane storm surges in St. Andrews Bay, off the Gulf of Mexico took advantage of the speed and durability of CON/SPAN^®. The structure has 6500 PSI Class V concrete with moisture inhibiting admixture (calcium nitrite). Additionally, it has cast-in- place AASHTO/FDOT barrier walls on the headwall and wingwalls at one end, and separating the traffic lanes from the pedestrian lane on the other.

This 28-foot span x 7-foot rise CON/SPAN^® structure rests on beams cast atop ten 36-inch drilled shafts. In addition, 15 feet deep prestressed concrete sheeting is used, which protects the foundations from scour. This bridge was part of a resurfacing project on U.S. Highway 98 in Panama City, Florida.
