Central Artery / Tunnel Electrical Finishes

Boston, Mass.

The goal of the Central Artery/Tunnel project, more commonly know as the “Big Dig”, was to replace the six-lane elevated highway with an eight-to-ten-lane underground expressway directly beneath the existing road, culminating at its northern limit in a 14-lane, two-bridge crossing of the Charles River. After the underground highway opened to traffic, the crumbling elevated highway was demolished and in its place is open space.

Central Artery/Tunnel Electrical Finishes

Boston, Mass.

When it opened in 1959, the original Central Artery comfortably carried about 75,000 vehicles a day. By the late 1980s, it carried upwards of 200,000, making it one of the most congested highways in the United States.
