The Shands Bridge over the St. Johns River is a new 9,282-foot-long bridge with a typical width of 102 feet. Working in partnership with the lead designer, H&H is the Engineer of Record (EOR) for the substructure design, which includes three primary pier types designed to withstand large vessel collision forces. The lower-level approaches utilized 60-inch prestressed concrete cylinder pile bents, eliminating the need for waterline footings, while the high-level approach spans featured individual footings for each pier column. The main-span unit had combined footings supported by 30-inch square prestressed concrete piles. H&H is also serving as the toll site designer, which includes retaining walls, sign structures, and three sites with buildings and gantries
The project includes the replacement twin bridges carrying SR 23 over SR 16A, SR 13, and Bayard Access Road, and a single bridge over an equipment crossing. Miscellaneous structures include retaining walls, sign structures, and three tolling sites with buildings and gantries. The SR 13, Bayard Access Road, and Equipment Crossing bridges will each have a single span, while the SR 16A Bridge features a two-span design with a multi-column pier. The new Shands Bridge incorporates multi-column piers with aesthetic features and a wraparound spill-through abutment with Riprap, while all other bridges on the project will feature wrap-around MSE wall abutments.
The project is now in construction, with anticipated completion in 2030.
