Highway Drainage for Proposed Interchange, Waterville, ME

Northstar Hydro worked with FST and Maine DOT to provide hydrologic and hydraulic design services for a new exit ramp from the Maine Turnpike. Northstar conducted a hydrologic analysis, drainage review, and/or sizing design of 17 cross culverts: 5 new culverts, 6 culvert extensions, and 6 additional culverts beyond the project but reviewed as part of the drainage design.  The project involved an analysis of the final drainage design for a proposed new interchange on I-95 at Trafton Road in the City of Waterville and the Town of Sidney in Kennebec County, Maine.  The design is a partial cloverleaf interchange with both ramp sets located south of Trafton Road.  Design parameters included fish passage considerations.
