DuBois & King is the Lead Design Engineer for a $15.2M culvert replacement design-build project in Ryegate, VT. Deteriorated undersized culverts have contributed to flooding of US Route 5 and the backwater jeopardized the integrity of the roadway and rail embankments. The design-build team of DuBois & King and Engineers Construction (ECI) are working with the Vermont Agency of Transportation to construct two buried 32-ft-wide by 16-ft-high, cast-in-place, reinforced concrete arch culverts beneath the roadway and rail line. The new culverts are 144 ft and 128 ft in length, and will increase the hydraulic capacity by 25 times the existing capacity.
Excavations up to 70-feet deep have been completed and concrete is being poured. All of the footings have been completed and ECI is now forming and pouring the cast-in-place concrete arches. Concrete pours are expected to continue throughout the winter. The contractor is utilizing special cold-weather procedures, including heating and blanketing the fresh concrete to protect it from freezing as it cures.
