Ted Williams Tunnel
Boston, Massachusetts
| Designer: | Bechtel/Parsons - Brinckerhoff |
| Contractor: | Various |
The Ted Williams Tunnel doubles Boston's traffic capacity under Boston Harbor to Logan Airport from four lanes to eight. The 2.6 km (1.6 mile), $1.3 billion tunnel, includes a 1.2 km (3/4 mile) underwater section consisting of tubes placed in a trench dredged on the harbor floor. The tunnel was initially only opened to commercial traffic while local highway connections are completed. When the connection to the Massachusetts Turnpike is finished (expected in 2001) the tunnel will complete 1-90 from coast to coast.
