he Big John Monahan Bridge Carriers SR-710 over the St. Lucie River Canal and Kanner Highway. The design build of the bridge consists of a twin six span major bridge with main spans of 185ft. The bridge supports a conventionally reinforced concrete deck that is supported on prestressed Florida I Beams. The span arrangements were skewed for efficiency and aesthetics along the St. Lucie Canal. The substructure consists of reinforced hammerhead piers supported on pile foundations. The cantilevers for the hammerhead piers are approximately 28 ft. from centerline of column. This project required heavy coordination with the following agencies: US Coast Guard, Army Corp, South Florida Water Management, DEP, Martin County, Indian Town, and CSX. The project also included some other notable perspectives: Rail Road Coordination, Existing Bridge Demolition, Lead Paint, Wetland Impacts, and Hydraulic Analysis. This Bridge is Classified as a Category II structure requiring independent peer reviews. Lakes Engineering’s was responsible for the complete design of this Category 2 Bridge over the St Lucie River; including the complete design of all elements of the superstructure and substructure, permits, geometric layout, load generation for gravity, and lateral, longitudinal and time dependent. Lakes Engineering’s personnel has also provided post-design services, including review of shop drawings, RFI, RFC, and RFM. Lakes Engineering’s personnel provided construction engineering services throughout the construction of the Bridge.
