Neshobe River Bypass Culvert

Brandon, Vermont | Town of Brandon

The Neshobe River crosses through the heart of downtown Brandon, and the historic stone masonry bridge carrying Central Street/US 7 and numerous utilities had a history of substantially inadequate hydraulic capacity. As a demonstration of this issue, the town opened the front and rear doors of the adjacent town offices during a large storm event to pass the additional storm flows without destroying the building or the adjacent bridge. D&K designed a 278-ft-long bypass culvert with a sloped, tapered inlet and baffle blocks at the outlet; this structure has successfully passed storm events since its construction in 2019. The project’s construction was coordinated with an adjacent $20M roadway and utility reconstruction project and the rehabilitation of the historic bridge. Challenges included avoiding historic building foundations and basements and subsurface utilities (mapped and unmapped).
