Northbound lanes of interstate open in Big Dig

| 3/14/2003

The Big Dig, an underground highway system under construction in Boston, will open its next phase March 30 when the northbound lanes of I-93 are put to use under the city, The Boston Globe reported March 14.

The opening will also include the Bunker Hill Bridge, a cable-stayed bridge over the Charles River. The bridge is reportedly the widest bridge of its kind in the world.

The opening is the second milestone this year for the project, the largest highway construction project in the United States. Earlier, the I-90 connector to the Ted Williams Tunnel and Logan Airport opened to general traffic. The new connector extends the MassPike from its old terminus at I-93 near South Station and Chinatown under the rail tracks and under the Fort Point Channel through to the Ted Williams Tunnel and into Logan Airport.

However, this month’s opening is far more significant, representing a larger portion of the entire project, which is scheduled to be complete by early 2004. The Globe reported that a series of lane closures and restrictions would be used to move traffic from the northbound lanes of the current elevated highway and into the tunnel system.
