Monitoring Committee | The CCRPC is in the process of forming an I-89 Monitoring Committee based on the recommendation of the implementation plan.

Final Report | The I-89 2050 Study Final Report is available.

Implementation Plan | The Implementation Plan identifies and prioritizes the projects and programming necessary to guide the corridor toward the Vision of a safe, sustainable, resilient, reliable, and efficient interstate mainline and interchange system over the next 30 years. The Implementation Plan was unanimously supported by the project’s Advisory Committee at their meeting on May 18, 2022.

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 an auxiliary route, Interstate 189, which is accessed via Exit 13 in South Burlington. Seven interchanges are within Chittenden County spanning the numbered designations 11 in Richmond at the south through 17 in Colchester at the north.

The broad intent of this study was to assess the safety and capacity of Interstate 89, identify existing and future multimodal needs, develop and evaluate improvements, examine transportation and land use impacts of new or expanded interchanges, determine asset management/maintenance needs, and develop an implementation plan for short, medium, and long-term multimodal investments.

TECHNICAL COMMITTEE

A technical committee composed of members from VTrans, Federal Highway Administration (FHWA), the Cities of Burlington and South Burlington, and the CCRPC focused on the key technical issues and decisions that needed to be advanced during the course of the study —including goals and criteria, confirmation of data collection, technical design criteria, inputs to scenarios, and the technical review of the alternatives and final plan recommendations. This group functioned as a body to ensure quality from a technical standpoint on analyses which were used for decision making throughout the life of the project.

background

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.
