Signage for US 20 and NY 5 along its former routing in downtown Canandaigua. The duplex was rerouted onto a bypass that was built and opened to traffic in 1981. Somehow, this sign assembly was overlooked for over 20 years, and even survived a sign rehab project in late summer 1993. However, it was finally removed in 2005.
