The bridge that carries Reservoir Road across Ulster County's Ashokan Reservoir, known by the New York City Department of Environmental Protection as the Dividing Weir Bridge, is exactly 100 years old this year. The bridge's 15 concrete arches were built in 1915, and are beginning to show some wear and tear.
On Wednesday, Feb. 25, the DEP installed temporary traffic signals at both ends of the bridge, which is located in the town of Olive, to reduce traffic over the span to one lane while workers shore up the concrete arches, according to a press release. The span will be back to two lanes of traffic this fall.
The bridge is slated to be replaced completely in the next ten years.
