Pipeline Crossings Lead to an Environmental Miracle in Cambridge, Massachusetts

The City of Cambridge, Massachusetts recently completed the phased construction of over one mile of reinforced concrete pipe (RCP) up to 54-inch diameter and reinforced concrete box culvert (RCB) up to 12- x 5-foot as part of its CAM 004 combined sewer separation program. Installation occurred at shallow depth of cover complicating many pipeline crossings including a commuter railway corridor, three state-operated sewer interceptors, and arrays of duct banks and utilities. These crossings occurred on state owned parkways congested with traffic, roads with dense private utilities, and office complexes sensitive to outages. The mile long corridor required eight new easements through valuable commercial developments, State- land and railways. The problems facing each crossing are identified, and the design approach along with construction changes are detailed. This project exemplifies how to construct large diameter pipelines via the open-cut method in dense urban corridors.
