CTDOT Announces Upcoming Infrastructure Improvements on the Waterbury Branch; Substitute Busing Necessary

May 6, 2021

The Connecticut Department of Transportation (CTDOT) recently announced the continuation of infrastructure improvements on the Waterbury Branch this spring and summer, requiring substitute bus service to replace train service. The construction program includes completion of the new passing sidings, at-grade crossing improvements, continuation of tie replacement and track upgrades, and completion of the signal system.

The scheduled construction activities will require two phases of work that will require busing of Waterbury Branch customers:

  • The initial phase of the work will take place during overnight hours beginning on Monday, May 10, 2021, and continuing through Friday, May 28, 2021.

  • The second phase will begin on Tuesday, June 1, 2021, and continue through Sunday, August 29, 2021. During this period, substitute buses will operate between Waterbury and Bridgeport for all weekday and weekend service (details below). Express bus service between Waterbury and Bridgeport will be offered.
