Vermont’s First Diverging Diamond Interchange
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.

Welcome! The Exit 16 Diverging Diamond Interchange (DDI) Project Team is excited to share our newly redesigned project website.
