  Project Manager for the Vermont Transportation replacement of Bridge 8, a historic double leaf bascule bridge, that carries U.S. Route 2 over Lake Champlain between the towns of North Hero and Grand Isle. The bridge is the only vehicular movable bridge in the state of Vermont. The bridge will be replaced with a double leaf bascule bridge on a new foundation, with similar aesthetic and same draw width as the 1953 bridge it’s replacing. The project’s purpose is to ensure safe passage by providing a structurally stable roadway for the traveling public. Specifically,the project involves the replacement of the existing bridge along with associated roadway improvements and incidental items. The existing twin leaf bascule bridge provides an 80+ feet navigation channel. Consistent with the existing bridge structure, the new bridge will provide an 80+ foot wide navigation channel with 10 feet of clearance in the closed position (ordinary high water) and unlimited vertical clearance when open.
