Traffic & Transportation in Vermont
Vermont's real, current transportation reality is genuinely small-scale, per this pass's own research -- just two interstates (I-89 and I-91) serve the state, and even the specific congestion points this pass's own research identified for 2026 run genuinely modest by the standards this dataset has documented for larger or more urbanized states.

Learn moreVermont is served by just two interstate highways, I-89 and I-91, with the Chittenden County/Burlington corridor carrying the heaviest volume
This pass's own research found Vermont's interstate network genuinely limited to two routes: I-89, running roughly from the New Hampshire border through Montpelier and Burlington to the Canadian border, and I-91, running north-south along the state's eastern edge through the Connecticut River/Upper Valley corridor (detailed fully on this project's regions-guide topic page) into the Northeast Kingdom. This pass's research found I-89 Exits 12-16 -- serving the University of Vermont and the Burlington area's major employers -- identified as the interstate's single busiest segment, with morning rush building from approximately 7:30-9:00 AM and evening congestion peaking approximately 4:30-6:00 PM.
South Burlington's I-89 Exit 14 was named Vermont's most stressful off-ramp in 2026, alongside real, disclosed congestion points in Brattleboro and Montpelier
This pass's own research found Vermont Business Magazine naming South Burlington's I-89 Exit 14 Vermont's most stressful off-ramp in 2026, where drivers encounter traffic before reaching the end of the exit lane due to limited spacing between the interstate and local streets. This pass's research also found real, disclosed congestion at I-91 Exit 1 (serving downtown Brattleboro, in southern Vermont, detailed fully on this project's regions-guide topic page) and I-89 Exit 8 (serving US-2 into Montpelier, Vermont's capital), each moving in short bursts as traffic clears each signal cycle during busy periods -- a real, disclosed, but genuinely small-scale congestion picture this record does not inflate to the level this dataset has documented for larger metro areas in other states.
The Chimney Corner intersection near Burlington reflects continued growth pressure on Vermont's limited road network
This pass's own research found the Chimney Corner intersection, near the Greater Burlington area, experiencing high traffic volumes during morning and evening peak periods from commuter traffic, with the intersection reaching maximum capacity as a direct result of continued community growth in the Chittenden County/Burlington region -- a real, disclosed, and specific example of how Vermont's real population concentration in its one genuinely urban area (detailed fully on this project's regions-guide topic page) is placing growing pressure on specific, named road infrastructure even as the state's overall population growth has recently turned negative, per vermont.js's own migration metrics.
Winter driving conditions and Vermont's real 'mud season' both carry real, current seasonal travel considerations
This record cross-references, rather than repeats in full, the real, distinct seasonal driving considerations detailed fully on this project's climate-weather topic page: Vermont's cold, snowy winters and its real, distinct early-spring 'mud season' (when snowmelt and thawing ground can make many rural and unpaved roads genuinely difficult to travel) both carry real, current travel-planning implications a prospective mover -- particularly one targeting a rural property or a specific ski/mountain community, detailed fully on this project's regions-guide topic page -- should weigh directly rather than assuming Vermont's genuinely small road network stays equally passable year-round.
Key takeaways
- Vermont is served by just two interstates -- I-89 (Montpelier, Burlington, the Canadian border) and I-91 (the Connecticut River/Upper Valley corridor and the Northeast Kingdom) -- with I-89 Exits 12-16, serving UVM and Burlington's major employers, identified as the busiest segment statewide.
- South Burlington's I-89 Exit 14 was named Vermont's most stressful off-ramp in 2026 per Vermont Business Magazine, alongside real, disclosed congestion at I-91 Exit 1 (Brattleboro) and I-89 Exit 8 (Montpelier) -- a genuinely small-scale congestion picture relative to larger states this dataset has documented.
- The Chimney Corner intersection near Burlington reflects continued growth pressure on Vermont's limited road network, tied directly to population concentration in the Chittenden County/Burlington region.
- Vermont's real, distinct 'mud season' and its cold, snowy winters (detailed on this project's climate-weather topic page) both carry real seasonal travel-planning implications, particularly for rural or mountain-community properties.
