PortMiami Tunnel

The PortMiami Tunnel project was built in a public-private partnership (P3) and is the first large-diameter tunnel constructed in Florida's challenging soft sedimentary geology using a tunnel boring machine (TBM). The purpose of the PortMiami Tunnel is to relieve traffic congestion in downtown Miami by diverting car, truck, and bus traffic from nearby highways directly to the Port of Miami through twin 42-foot diameter tubes extending below the main ship channel. Langan evaluated the subsurface data to develop the geotechnical engineering parameters required for design of the bored tunnel and the TBM. We also observed and monitored early-phase testing consisting of foundation load testing and Cutter Soil Mixing for the U-wall and cut-and-cover portions of the project.
