Covid-19 Update

On March 24, 2020, Vermont Governor Phil Scott, in response to the global COVID-19 pandemic, issued the "Stay Home, Stay Safe" executive order directing the closure of in-person operations for all non-essential businesses in Vermont.

This order directly affects the operations of Vermont's transportation construction contractors and public and private utility companies. As such, the pandemic and its impact on these companies and organizations is expected to create delays in the Exit 16 DDI Project timeline, including construction.

As information becomes available, the Exit 16 DDI Project Timeline will be updated. Please check for the latest anticipated schedule.

About the Project

The Vermont Agency of Transportation (VTrans) is improving the roadway along the US Routes 2/7 corridor, in the vicinity of I-89 Exit 16, to enhance mobility and safety in Colchester, Vermont. The project area extends from in the Colchester-Winooski town line north for approximately 1 mile to just beyond the intersection of Sunderland Woods Road at US Route 2/7. The core of the project is to reconfigure the existing tight diamond interchange to a Diverging Diamond Interchange at I-89 Exit 16. Other improvements include:

  • Adding turn lanes at the Mountain View Drive, Hercules Drive and Rathe Road intersections.
  • Construction of dedicated pedestrian and shared pedestrian/bicycle facilities.
  • Modernizing traffic signals at South Park Drive, I-89 Exit 16, Mountain View Drive, Hercules Drive, Rathe Road and at Tigan Street in Winooski City.

The current interchange at Exit 16 is a grade separated tight diamond interchange with Interstate 89 crossing over US Routes 2/7 via two bridges. The existing interchange yields frequent traffic congestion, lengthy delays, and significant queuing during peak hours. These existing conditions are a safety concern with a high number of incidents, collisions and a lack of accommodations for non-motorized travel.
