Ryegate Culvert Design-Build Replacement Project
ECI is the Design-Build contractor to the Vermont Agency of Transportation for this $15.248M culvert replacement project. The undersized and failing existing culverts conveyed the waters of the Manchester Brook (a tributary to the Connecticut River) below the US Route 5 and Washington County Railroad embankments. This particularly challenging project involved replacing the culverts with a new 32-ft clear span opening below the 70-ft-tall railroad embankment and 60-ft-tall highway embankment. The project included temporary bridges and tieback-braced sheet pile walls to construct the culvert without closing the highway and with only limited weekend track outages on the railroad. ECI’s design partners (Dubois & King and Boscarding Consulting) designed a 32-ft concrete arch supported on pedestal walls and footings. The concrete was done as cast-in-place due to the challenges of installing heavy precast arches below the temporary railroad bridges and with only limited site access from the embankments.
