The Vegas project, called the Vegas Loop mega tunnel, is a two-tunnel 1-mile loop which connects the Convention Center with the Las Vegas Strip, at a cost of $52 million.

The LA project is a four-mile tunnel to connect a rail station with Ontario International Airport.

Civil engineers say it’s tough to build tunnels in South Florida, which is largely on a foundation of limestone, which is sponge-like, allowing water to move through it easily. However, large diameter tunnels are possible in South Florida if proper planning and precautionary measures are taken, said Conrad Felice, a professor of civil engineering at the University of Florida.

Felice noted that engineers earlier this decade completed the 4,200-foot Port Miami Tunnel, which had a price tag of $668.5 million and took over five years to complete.  That tunnel runs 120 feet below the surface.
