Mile Point Training Wall Reconfiguration

Jacksonville, FL


    • Design-build
    • Cutter suction and clamshell dredging
    • Wetland creation
    • East Leg Training wall comprised of armor stone and stone-filled marine mattresses
    • West Leg Training Wall consisted of 504 contiguously placed Concrete Structural Units (CSUs), approximately 4,000 ft. long, which acted as a wave attenuation structure and barrier for the wetlands
    • CSUs were an innovative alternative by Manson and our design partner as an alternative to the original specified design

This design-build coastal reconfiguration and dredging project for the U.S. Army Corps of Engineers involved building training walls to control the flow of the St. Johns River where it intersects with the Intercoastal Waterway near the Atlantic Coast. The training walls help minimize crosscurrents and aid in vessel navigation.
