Interstate 189 (I-189) is an auxiliary Interstate Highway in Chittenden County, Vermont. The spur extends for 1.49 miles (2.40 km) from I-89 exit 13 in South Burlington to US Route 7 (US 7) at the Burlington city limit. I-189 is the only auxiliary route of I-89 and the only auxiliary Interstate Highway in Vermont.

Route description

I-189 serves as an Interstate-grade connector between I-89 and a commercial district along US 7 (Shelburne Road). It is signed as an east–west highway. Prior to 2010, only one directional sign had been posted on the highway, on the eastbound side after the on-ramp from US 7. Sign replacements and additions in late 2010 added directional signs on both the eastbound and westbound sides of the route.


Unused section of the Champlain Parkway to the west of US 7; the current interchange is visible in the distance. Construction has begun on this segment since then.

The concept of I-189, named as the Southern Connector, and the Champlain Parkway into the city of Burlington along the waterfront and service an industrial area was first made in the mid-1960s. Construction began in the 1980s but was delayed due to the presence of a toxic barge canal on Pine Street.[2] The alignment was planned go through the barge canal. C-1 Segment I-189 to Home Avenue was built in 1989, but construction was again delayed due continued legal challenges. These challenges mostly came from the Pine Street Coalition, who argued the project was unnecessary and too costly as well as discriminatory due to the increased traffic in the low-income and minority residents of King and Maple streets neighborhood. The Champlain Parkway project were eventually canceled as the city largely left behind its industrial past in favor of tourism in the 1980s and the roadway was abandoned just beyond the US 7 interchange. As a result, Jersey barriers are in place on I-189 west directing traffic onto the US 7 offramp, orphaning approximately 0.65 miles (1.05 km) of road, along with a few ramps. More support of the project in recent years has led to a resumption of construction.[3]


The federal government previously gave the state a deadline to make a final decision on building the extension or they would lose matching funds. In early 2012, consensus settled on a two-lane parkway named the "Champlain Parkway" that will run northerly from Home Avenue for about 0.7 miles (1.1 km), then curve onto existing city streets in order to funnel traffic into downtown away from US 7.[4] I-189 will extend westward, then turn to the north, terminate at Home Avenue, and connect to the parkway. In August 2014, the parkway received its land use permit, clearing the way for the project to begin.[5] Opposition to the $30-million project and changes to its design led to delays in construction,[6][7] which finally began in June 2022.[8] Parts of the road are slated to open in mid-2024, with the entire highway going into service in 2027.[3]
