PLYMOUTH, Vt. – Construction is progressing on Plymouth’s Bridge 9 project, with a significant traffic shift now in place on Vermont Route 100A. As of this week, the southbound lane leading to Bridge 9 is closed, and traffic is being regulated using a temporary signal system. For specific construction tasks, flaggers will also be present to manage vehicle flow.

This traffic pattern is expected to remain in effect until July 7, when a full closure of Bridge 9 is scheduled to commence. The closure is part of a larger infrastructure improvement initiative to modernize the aging bridge and enhance long-term safety and mobility along this corridor.

In addition to the Bridge 9 work, nearby Bridge 4 will see new activity starting June 24. According to the construction update, ADA Traffic Control crews will be managing flagging operations and temporary signage, while geophysical survey staff conduct lane-specific testing.

The survey work on Bridge 4 will begin in the northbound lane and is expected to take only a few hours per lane, with the full task anticipated to be completed in a single day, minimizing disruption for drivers.

Crews are currently focusing on setting up demolition containment at Bridge 9 and beginning partial demolition of the existing structure, marking a new phase in the construction process.

Local officials emphasized the importance of driver awareness and patience during the ongoing work. “Motorists are urged to use caution in the area, adhere to signal instructions, and be prepared for minor delays,” said a Vermont Agency of Transportation (VTrans) spokesperson.

The bridge work is part of the state’s broader effort to rehabilitate aging infrastructure and improve rural transportation routes. Both Bridge 9 and Bridge 4 serve as critical connections for residents, travelers, and emergency services in Plymouth and surrounding communities.

Residents are encouraged to monitor local advisories and VTrans updates as the project progresses, particularly leading up to the full closure in July.
