Until recently, the only way to drive between Route 11 and Interstate 81 near Fort Drum was a two-lane road, Route 342. As the Army base grew, local businesses flocked there to serve the increasing traffic. But the state built an $87 million bypass to ease traffic and give military vehicles a direct route to Fort Drum’s main gate. I-781, as it’s known, opened last December. Local shop owners have had mixed reactions to the new road.
