The I-495 Bridge Bundle project in Lowell and Tewksbury is moving into later stages of construction this spring. The $36.8 million innovative "Design-Build" project is funded by the Patrick-Murray Administration's historic eight-year, $3 billion Accelerated Bridge Program to repair or replace structurally-deficient bridges.
The work begun in 2009 includes complete replacement or reconstruction of the bridges that carry I-495 over the Concord River, the MBTA Railroad and Woburn Street in Lowell. As a "design-build" project, the design team headed by The Middlesex Corporation is responsible for
bringing the work through the design phase to completion of construction.
As of the end of February, work continues on all three bridge sites. Motorists are reminded that the southbound on-ramp from Woburn Street is closed and a detour in effect; temporary traffic signals are in place at both the north and southbound ramps to ensure the efficient flow of detoured traffic.
During the weekend of February 19-20, precast deck panels were installed on the new section of Concord River Bridge, left. Next steps include grouting the joints between panels to create a solid slab. The second half of this bridge will also be built using precast panels.
