Interstate 189 (abbreviated I-189) is an auxiliary Interstate Highway in Chittenden County, Vermont, United States. The highway extends for 1.488 miles (2.395 km) from Interstate 89 exit 13 in South Burlington to US Route 7 at the Burlington city limit. I-189 is the only spur on the entire length of I-89.

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.

History

There was once a plan for the highway to continue north into the city of Burlington along the waterfront and service an industrial area.[2] Construction was delayed due to the presence of a toxic barge canal[3] and eventually cancelled as the city largely left behind its industrial past in favor of tourism in the 1980s. 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 off-ramp, orphaning approximately 0.65 miles (1.05 km) of road, along with a few ramps.

Unused section of 189 to the west of US 7; the current interchange is visible in the distance.

Future

The Federal Government previously gave the state a deadline to make a final decision on building the extension or they would lose matching funds. As of Spring 2012, consensus is for a two-lane parkway named the "Champlain Parkway" that will curve northerly onto existing city streets in order to funnel traffic into downtown away from US 7.[4] In August 2014, the parkway received its land use permit, clearing the way for the project to begin.[5]

Exit list
