The centerpiece of the Program is the replacement of the 124-year-old Norwalk River Railroad (Walk) Bridge. A 240’ vertical lift bridge was selected to replace the current four-track swing bridge. This option was advanced out of more than 70 alternatives due to having the smallest environmental footprint, the shortest overall construction schedule, the shortest period of navigation and rail restrictions and the lowest cost of all other movable alternatives. Other projects in the Walk Bridge Program include the Danbury Branch Dockyard Project in South Norwalk and the CP243 Interlocking Project on the mainline between East Norwalk and Westport. The superstructure replacement of the Osborne Avenue Bridge, the East Avenue Bridge Replacement and Roadway Improvement Project, and the Fort Point Street Bridge Replacement and Roadway Realignment are also included in the Program.
