Concord, MBTA New Bridge, August 28, 2015As part of the ongoing rehabilitation of the Fitchburg Commuter Rail Line, the MBTA is replacing the old railroad bridge over Route 62/Main Street in Concord with a new bridge to be rolled into place Saturday, August 29.

The current bridge has low clearance and is in poor condition which restricts train speed over the bridge to just 25 mph. To minimize the impact of the replacement work to rail and road traffic, the MBTA is using an accelerated bridge replacement process to “roll-in” the new bridge.

“Traditional construction techniques would have required the roadway to be closed for a month and rail service to be interrupted for a nine day period,” said MBTA General Manager Frank DePaola. “By using the ‘roll-in’ process, almost all of the work is taking place over the course of one weekend.”

Commuter Rail customers will be bused around the construction site this weekend.

Construction crews have been working since last year, preparing foundations for the new bridge. The new bridge structure was assembled over the roadway adjacent to the existing bridge. The track will be removed and the existing bridge demolished tonight. The new structure, supported on two 80 wheel transporters, will then be slowly rolled into place Saturday morning. New track will then be installed and the line will be returned to service in time for the regularly scheduled start of Commuter Rail service Monday morning.

The new bridge over Route 62/Main Street will be two and a half feet higher over the roadway, will have a wider sidewalk, and will allow Commuter Rail trains to continue at the normal speed of 65 mph.

The $9 million Route 62 Bridge replacement is part of the $300 million Fitchburg Line Improvement project which includes the rehabilitation of 7 bridges, the installation of 9 miles of new track, the construction of new accessible stations in Littleton and South Acton, and the modernization of track and signals throughout the 50 mile line.

“When the work is completed at the end of this year, Commuter Rail service on the Fitchburg Line will be faster and more reliable,” said General Manager DePaola.
