State highway officials will hold a hearing in Lexington next week to discuss replacing the Route 2 bridges over Interstate 95-Route 128.
The project is in an early design phase, and construction is expected to begin at the busy interchange in 2014, according to Michael Verseckes, a spokesman for the state Department of Transportation.
The hearing on the project will be held Tuesday, Feb. 12, in the Cary Memorial Building’s Battin Hall at 1605 Massachusetts Avenue.
“This is really the first chance that we have to bring something out to the public that they can see what it is going to look like,” Verseckes said.
Two bridges carry Route 2 over I-95-Route 128, and Verseckes said they have both been deemed structurally deficient and will be replaced. The cost of the project is estimated at $33.7 million.
Verseckes said the new bridges will also be raised higher to provide more clearance over I-95. The bridges currently have 14 feet four inches of vertical clearance over the interstate below, and will be raised to 16 feet six inches to meet new Federal Highway Administration standards.
Ramps to the interchange will also be improved to help traffic flow, Verseckes said.
More than 55,000 vehicles travel the section of Route 2 per day, according to a 2009 road safety audit by the Massachusetts Highway Department, which is now part of the state Department of Transportation.
Verseckes said the bridge replacement project will be done in several phases to allow vehicles to pass through the interchange on both Route 2 and I-95-Route 128.
The new westbound bridge will be constructed first in the median area, and once it is complete the Route 2 eastbound traffic will be shifted to the new bridge.
The existing eastbound bridge will then be removed and the new bridge built, Verseckes said. The eastbound traffic will then be shifted back to the new eastbound bridge, and westbound traffic will be shifted on the new westbound bridge.
Written statements about the project can be submitted to the state within with 10 business days of the public hearing and should be sent to Thomas F. Broderick, P.E., Chief Engineer, MassDOT, 10 Park Plaza, Boston, MA, 02116, Attention Project Management Section, Project File No. 600703.
