Chittenden County is home to a little over 37 miles of Interstate 89 which is the only primary interstate highway within Chittenden County. An additional 1.5-mile spur of auxiliary Interstate 189 is accessed via Exit 13. Seven interchanges are within Chittenden County spanning the numbered designations of 11 through 17. Congestion and safety issues on Interstate 89 have long been a topic of conversation and were last systematically examined in the 1997 Chittenden County I-89 Corridor Study.

Proposed new interchanges and multi-modal mobility issues at existing ones have been examined over the years and study reports can be found on the CCRPC Studies and Reports Database. Off ramps at Exits 11, 12, 14 and 15 have been expanded via additional lanes. In addition, plans for major improvements at Exits 16 and 17 are currently at various stages of development by VTrans. During the 2018 update to the CCRPC’s ECOS/Metropolitan Transportation Plan, it was determined it is time for a fresh look at the Interstate 89 corridor within Chittenden County.

The goal of this study is to assess the capacity of Interstate 89 and its existing interchanges within Chittenden County; identify current safety, operational, maintenance, and resiliency issues; assess future needs; develop and evaluate alternatives, including sketch level conceptual plans, that address identified issues for all modes of transportation; examine transportation and land use effects of possible mainline widening and/or new/expanded interchanges; evaluate climate change effects of alternatives; determine asset management/maintenance needs; and develop an implementation plan for interstate and interchange investments. The final I-89 Implementation Plan will be consistent with the broader 2018 ECOS Plan. This Study is expected to be completed in 2021.
