Route 2/I-95 Bridge
Replacement Project
Summer 2014
About the Project
The Massachusetts Department of Transportation
(MassDOT) is replacing the east and westbound
Route 2 bridges over Interstate 95 (I-95) in Lexington
as part of the Route 2/I-95 Bridge Replacement
Project. Route 2 is one of the main east-west
alternatives to the Massachusetts Turnpike and
carries approximately 67,000 vehicles a day. Built in
1960, the bridges are deemed “structurally deficient”
and “functionally obsolete.” The project will address
the current deficiencies, improve safety and reduce
expensive annual maintenance costs. It will also
make improvements to I-95 in the area.
The Work
construction for high quality, uniform, long-lasting
pavement. “Intelligent Compaction” uses vibratory
rollers equipped with an onboard computer reporting
system and Global Positioning System (GPS) mapping.
The process provides the operator with an on-board,
real-time record of the location and number of roller
passes as well as compaction data.
In an effort to minimize potential inconveniences,
MassDOT is committed to maintaining three travel
lanes in each direction on Route 2 during peak hours.
Travel will be restricted at times to one lane in each
direction, for a limited duration during off-peak
hours. Additionally, a minimum of four travel lanes
and an auxiliary lane in each direction on I-95 will be
maintained during the peak hours of 6 AM to 10 AM
and 3 PM to 7 PM.

Other project benefits include realigning and
reconstructing portions of Route 2 to improve
vertical clearance over I-95 and upgrades to
stormwater drainage and treatment. As part
of the project, a two-mile stretch of I-95 will
be resurfaced and will include a new median,
guard rails, wider shoulders, new roadway
markings and improved stormwater drainage.
The project also features MassDOT’s first use of
“Intelligent Compaction.” Compaction is one
of the most important processes in roadway
