Due to the volume of traffic within this area, this project is using accelerated construction for one or two days during nighttime hours (9:00 p.m. to 8:30 a.m.) on a Friday and/or Saturday to replace the drainage structure. There will be some daytime activities as well, but with minimal impact to the traveling public. There will be a designated detour along Interstate 89 and VT Route 15.

The anticipated completion is July 2022.
