CTDOT TO HOST ONLINE PUBLIC MEETING REGARDING MANRESA ISLAND AS PART OF WALK BRIDGE PROGRAM IN NORWALK
The Connecticut Department of Transportation (CTDOT) is hosting an online public information meeting on Tuesday, June 16, 2020, to discuss the potential use of a portion of Manresa Island in Norwalk as part of the Walk Bridge Replacement Project.
The online presentation begins at 6:30 PM. This meeting is being held to afford an opportunity for public participation and open discussion of views and comments the community may have regarding the proposed use of Manresa Island as a construction staging area for the upcoming Walk Bridge Replacement Project.
Residents who are interested in taking part in the online meeting can register at www.walkbridgeCT.com or tune in on the date of the meeting. If you are unable to attend the meeting, the presentation will be recorded and posted on the Program's website and the Walk Bridge Facebook page: www.facebook.com/walkbridgect on Thursday, June 18, 2020.

The Walk Bridge Program consists of several inter-related rail and infrastructure construction projects in Norwalk, CT. 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.
