VT Highway Slope Stabilizations

Ripton, Granville, Sharon, Hancock, Moretown, Vermont | Vermont Agency of Transportation

In the aftermath of Tropical Storm Irene, many roadways throughout Vermont were severely damaged due to flood waters from adjacent streams and rivers. For four sites along VT 100, 100B, 14, and 125, D&K designed slope stabilization and appurtenant roadway repairs; for a site on VT 125, D&K designed a small box culvert replacement. For each project, D&K worked in MicroStation and provided the water resource, civil, geotechnical, and structural design parameters to provide long-term stabilization. Slope repair sites ranged in size from a single site along approximately 1,000 feet of roadway to sites with several slope failure points over miles. Repairs typically consisted of drainage improvements, embankment armoring using riprap, and partial roadway surface and embankment replacement. The culvert replacement utilized accelerated bridge construction techniques, including a two-day closure to perform the cutting, installation of the structure, and filling and paving.
