GREENPORT – The Columbia County Department of Public Works will begin the construction work for the replacement of two structurally-deficient bridges, Wednesday, June 8.
The first project that will start June 8 is the replacement of Dinehart Bridge, which carries County Route 7A over the Roeliff Jansen Kill in the Town of Copake, about halfway between the hamlets of Copake and West Copake. The second bridge replacement commencing the same day is the replacement of Dean Bridge, carrying County Route 21 over a Roeliff Jansen Kill tributary in north Hillsdale.
Both County Routes 7A and 21 will close at their respective bridge sites Wednesday, June 8 for the start of the bridge replacement work and local traffic will be directed to use temporary, off-site detours that will be signed/posted by the county’s project contractors at each site. The bridge replacement work at each site is expected to take about four to five months to complete.
The temporary off-site detour for the Dinehart Bridge replacement in Copake will re-route traffic over Columbia County Route 7A (the Center Hill Road section) and a section of Columbia County Route 7 passing through Copake Lake and West Copake. The Dean Bridge off-site detour in Hillsdale will traverse sections of County Route 21, state Route 22, state Route 203 and Columbia County Route 7 in both Hillsdale and Austerlitz.
