Widening project
The Massachusetts Department of Transportation is proposing a $137 million project to widen the existing 2.4-mile four-lane highway section to six lanes, from north of Route 99 in Saugus to south of Route 60 in Revere. The project consists of adding a twelve-foot travel lane and ten-foot shoulder in each direction. Work also will include reconstruction of the Copeland Circle interchange by eliminating the existing rotary, and demolition of the existing 1957 bridges from the never-built highway extension. The Lynn Street/Salem Street interchange in Malden, and the Route 99 interchange in Saugus, will be reconstructed. Major rock blasting will be required for the project due to a massive ledge next to the highway. Seven bridges will be replaced and three others upgraded to handle the new lanes. The project is expected to begin in 2012 with completion in 2015.
