SR 64 (Manatee Avenue) from SR 789 to Perico Bay Boulevard - Anna Maria Island Bridge Replacement
This project involves designing a high-level fixed bridge to replace the existing bascule bridge to Anna Maria Island. The new bridge will be constructed to the south of the existing bridge and provide 65 feet of vertical navigational clearance and 100 feet of horizontal clearance between fenders. The existing Anna Maria Island Bridge will be demolished following the construction of the new bridge with the acceptable debris recycled on an artificial reef, where feasible. Additionally, this project includes the design of MSE walls and replacement of seawalls at both ends of the bridge. American worked closely with the Aesthetics Advisory Committee to evaluate architectural and aesthetic elements such as overlooks, pier flutes, logos, colors and textures, MSE wall features and geometrics, pedestrian barrier walls, and other features. Roadway approaches to the bridge will consist of two 12-foot-wide travel lanes, 10-foot-wide shoulders (7-foot paved for buffered bicycle lanes), 10-foot-wide sidewalks on both sides of the roadway, curb and gutter on the north side of the roadway (west of the bridge only), and a 45 mph design speed. A combination of reconstruction, milling and resurfacing, and widening will be used to reconfigure the travel lanes to match the new bridge. American is providing design for a two-lane roundabout at the intersection of SR 64 and SR 789 to replace the existing traffic signal. Improvements are also being made to the SR 64 and SR 789 legs of the intersection to accommodate the roundabout. No additional right of way is required for the roundabout. Due to the anticipated changes in traffic flow, the signalized intersection at SR 64 and Gulf Drive is being evaluated for conversion to a roundabout.
