McMahon was responsible for traffic management strategies for six bridge locations as part of the Lowell Canal Bridges TIGER Grant project for the City of Lowell. McMahon gathered the necessary data and generated temporary traffic management plans (TMPs) proposing a full vehicular detour while maintaining pedestrian activity at one location, single-lane closures and a single alternating travel lane through the work zone at the remaining five locations. Several of the locations were situated in downtown settings in addition to being in the vicinity of the University of Massachusetts-Lowell (UML). The TMPs were coordinated and submitted to the City of Lowell, UML and MassDOT that were approved and will be implemented during construction. Design documents include TMPs and traffic management item cost estimate. McMahon was also responsible for environmental coordination and permitting for the project, including preparation of a NEPA Categorical Exclusion, and coordination with regard to Section 106 of the National Historic Preservation Act of 1966, due to the historic nature of the Lowell canal system; and preparation of a Section 4f) de minimus finding for easements over parkland. The canals are a defining feature of the Lowell National Historical Park. McMahon was responsible for MassDOT’s Early Environmental Coordination Checklist, and preparation of five applications for Section 401 Water Quality Certificate from MassDEP, and a Section 404 permit from the United States Army Corps of Engineers.
