Writing in the Register-Star, John Mason has a rundown of three major bridge projects currently underway in eastern Columbia County. All of the projects require detours. The first is the Dinehart Bridge. Dinehart carries county Route 7A over the Roeliff Jansen Kill in Copake. Traffic is being rerouted over the Center Hill Road section of county Route 7A and a section of county Route 7 passing through Copake Lake and West Copake. The work began June 8 and should take five to six months. The Dean Bridge on county Route 21 is the second project. It crosses a tributary to the Roe Jan Kill. The bridge and the road will be closed until the new bridge is constructed, which is expected it to happen by late September. The detour for the Dean Bridge project takes the westbound motorist north on county Route 22 to Route 203, west to county Route 7 and south to county Route 21. The third project is the replacement of the large culvert that carries county Route 24 over Indian Creek in the southwestern corner of Canaan, in the hamlet of Red Rock. The detour for this project reroutes local traffic beginning at county Route 24. All three projects are being handled by William J. Keller & Sons of Castleton-on-Hudson.
