The Vermont Agency of Transportation is replacing a failing culvert deep below I-89 in Richmond near the park and ride.

A one-mile-long lane closure is in effect in both travel directions just south of Exit 11 as southbound traffic is merged to the northbound lane using a crossover. Barriers are now in place along the project area to separate excavation work from the traveling public.

This project is schedule to be completed in November 2022.

For questions/concerns regarding this project or to receive weekly project updates, you may email Stephanie Barrett, Public Information Consultant at sbarrett@coibsinc.com or call 802-399-7847. Please reference I-89 Richmond.
