These improvements were intended to mitigate impacts of a Costco expansion project located on Daggett Drive.

In addition to utilizing the latest MassDOT standards and project coordination with MassDOT District 2 and MassDOT Highway and Traffic Divisions, the project included revising the existing adaptive traffic signal system to accommodate the new phasing and approaches. McMahon was contracted for both traffic signal and roadway design for these improvements including: signal phasing and timing at the intersections of Route 5 at Daggett Drive and Route 5 at Morgan Road; roadway widening and realignment to accommodate a new left turn movement out of Daggett Drive and a dedicated left turn lane out of Morgan Road Extension; pedestrian improvements, including approximately 2,000 feet of sidewalks; and right-of-way coordination.

McMahon was responsible for preparing construction plans and contract documents and for coordinating with the Town of West Springfield and MassDOT. This project was completed on-budget and on-schedule, and constructed in 2019.
