Ted Williams Tunnel It was the first major milestone in the Central Artery/Tunnel Project.

The Ted Williams Tunnel beneath Boston Harbor opened on schedule and within its $1.3 billion budget 15 years ago today, December 15, 1995.

The Boston Red Sox legend himself joined the official opening ceremonies on that day.

The Ted Williams Tunnel completion doubled Boston's cross-harbor tunnel capacity from four lanes to eight.

The .75-mile underwater part of the 1.6 mile tunnel was built using a dozen steel tube sections, each longer than a football field, that were sunk into a trench on the Boston Harbor floor and connected together.

Along with the completion of the I-90 Extension, the Tunnel provided motorists from south and west of Boston direct access to Logan Airport, saving drivers as much as 45 minutes off the previous route.
