Drivers traveling along Route 100A should prepare for ongoing delays and a full closure later this summer as construction ramps up on Bridge 9 in Plymouth. The Vermont Agency of Transportation (VTrans) has initiated a long-term project to replace the aging structure over Pinney Hollow Brook.
A southbound lane closure is currently in effect near Bridge 9, with traffic controlled by temporary signals and occasional flaggers. This traffic pattern will remain in place until July 7, when a full closure of the bridge is scheduled to begin. The closure will last 42 days, through Aug. 17, to allow for complete removal and replacement of the span.
Bridge 9, originally built in 1984, is a 31-foot-long single-span concrete slab bridge. While rated “good” in several structural categories, signs of deterioration—including cracking, spalling, and exposed rebar—prompted the decision to replace it.
This week’s construction activity will focus on demolition containment and partial demolition of Bridge 9 in preparation for the full closure.
The bridge is located at mile marker 3.976 on Route 100A, approximately 3.7 miles north of Route 100.
