Wilton rail riders will find that buses will replace trains on the Danbury Branch rail line this weekend as the state Department of Transportation works to remove overhead catenary wires. Buses will be substituted for trains between South Norwalk and Danbury from Friday night, Nov. 17, through Sunday, Nov. 19.

This project, known as the Danbury Branch Dockyard Project, is one of the first construction projects in the Walk Bridge program, a series of projects that will replace the 121-year old movable bridge over the Norwalk River.

The Dockyard project will electrify the southern portion of the Danbury Branch, where it splits from the mainline, to the crossing at Jennings Place, approximately one mile north in the area formally known as the Dockyard in Norwalk.

The project also includes the addition of two new track sidings, track replacement, signal work, new catenary systems, structures, and the replacement of the rail bridge superstructure over Ann Street in Norwalk. The superstructure replacement will include new weathering steel deck spans, which will maintain the 19th Century character of the bridge.

The existing Walk Bridge, constructed in 1896, carries approximately 200 trains and 125,000 passengers daily, and ridership is projected to double by 2065.
