Project Brief
The Suncoast Parkway Trail over State Road 50 was a component of the Suncoast Parkway Trail, which parallels the Suncoast Parkway. This project consisted of an 883 foot long pedestrian/bicycle bridge over SR 50 in Hernando County. The approach spans of the bridge consist of flat slab units supported on shallow foundations, while the main span consists of twin steel girders, approximately 165 feet in length, supported on pile foundations.
Because of ADD requirements and to limit the length of the bridge, a maximum grade for the structure was utilized along with the required level landings spaced at 30 foot intervals. To avoid encroachment on right of way at the north end of the project, a unique reverse curve along with a superelevation transition was applied. Aesthetics of the bridge matched that of adjacent structures on the Suncoast Parkway, with the use of curved pier caps, weathering steel and coordinated concrete finishes.
This project consisted of six miles of paving a 12- foot-wide bikeway paralleling the Suncoast Parkway, including design of an 833-foot-long pedestrian bridge using a single span steel girder and concrete approach spans. The main span was 167-feet-long and utilized weathering steel to blend with surrounding structures. TCP plans used innovative pilot cars to lead emergency vehicles through detour site while traffic on SR 50 was closed to set the girders.
