PORT OF MIAMI TUNNEL: CONSTRUCTION, DESIGN AND INNOVATIONS
The Port of Miami Tunnel project is a highly complex project that includes design, build, finance, operation and maintenance. This project is a 35-year concession agreement between the Florida Department of Transportation (Owner) and MAT Concessionaire, LLC (Concessionaire), which includes 55 months for design and construction being carried out by Bouygues Civil Works Florida (BCWF). Jacobs Engineering is the Engineer of Record for the tunnel, as a sub-consultant to BCWF.
The main tunnel structure consists of two 37-foot internal diameter bored tubes running east to west with four connecting cross-passages, each 15 foot in diameter and ranging from 15’ to 75’ in length.
The eastbound and westbound bored tunnels are 3,700’ and 4,000’ long, respectively. The bored tunnel lining consists of two-foot thick universal precast segments with flat joints. The tunnel is being designed for a 150-year life. A closed-face shield machine, with earth/fluid pressure balance technology, was used to construct the tunnel.
