River Street and Western Avenue Intersection Project, Boston

Boston/Cambridge, Massachusetts

The replacement of the River Street and Western Avenue Bridges over the Charles River provided a unique opportunity to provide multi-modal and green infrastructure improvements to this highly travelled corridor. HSH, working with a prime consultant, advanced a “complete streets” solution for commuting traffic, cyclists and pedestrians. The plan was developed through MassDOT with a robust community engagement plan, led by HSH, that sought input from Walk Boston, Liveable Streets, MassBikes, and the cities of Boston and Cambridge.

HSH designed Stormwater Best Management Practices (BMPs) to control and alleviate nonpoint source (NPS) pollution in the lower Charles River Basin. HSH successfully obtained approval from both the City of Boston and City of Cambridge Conservation Commissions and is currently seeking MassDEP Water Quality Certification approval.

Stormwater treatment improvements were designed in accordance with the Massachusetts Stormwater Handbook to improve the water quality of the runoff and provide recharge opportunities.
