Causeway Street Elevated
Encyclopedia
The Causeway Street Elevated was a part of the MBTA's Green Line
in Boston, Massachusetts that ran roughly northwards from Haymarket
, then ran westwards for a short distance around the Boston Garden
indoor sports venue's exterior through the Green Line's North Station stop, and resumed a north-westwards direction past North Station and the Garden, ending at Science Park
. As the name suggests, the Elevated ran above ground, until it was closed in June 2004, being replaced by underground tunnel as part of environmental remediation to compensate for increased air pollution caused by the Big Dig
. Today, the Green Line emerges from the underground tunnel about halfway between North Station and Science Park, where it connects via ramp directly to the Lechmere Viaduct
, its only remaining elevated piece of track. The MBTA has no intention of running the remaining track on the viaduct underground.
The removal of the Elevated freed up land near the Big Dig
and lowered noise levels associated with the trains' characteristic screech as they rounded sharp turns in the track.
