I189 Questions
« on: December 20, 2021, 01:14:22 AM »

So, i did get to drive on i-189 today, and it is a confusing road. What is the actual history of it because the 1962 opening date the Interstate Guide gives isn't accurate since the road isn't listed until a 1973 Topographic map, it is MIA on 1970 and Earlier ones, and the original west end was a partial trumpet to US7, etc...

Questions

1: What are the actual dates the original 189 was built? The 89-US7 section, with the original loop/trumpet ending

2: When was the currently abandoned section built? It was built some time after 1986 using NETR historic aerials as a reference.

3: When was US7 converted to be an Overpass instead of an Underpass?

  • I-189 in its original form (with the trumpet at US 7 with 189 bridged over 7) was opened to traffic on 11/29/62.
  • The existing US 7 bridge over I-189 was built in 1988.  The reconfiguration of the 189/7 interchange and the abandoned section were built around that same time.
  • US 7 is and has always been the western end of I-189.  The abandoned section, what it was intended for, and what will eventually be built, was never part of I-189.

I can't find any record of 189 in topographic databases unlike other roads,but i trust your historical knowledge on this one, maybe interstates were not included on the maps in the 70s. Also the Narrative spread through the internet is that 189 was always intended to be more, but now it should be corrected to "189 was proposed at one point to be extended beyond Its original ending at US7"

Whatever maps you are finding are incomplete then.
I-189 appears on the Official 1964 Vermont Highway Map.
Andy and I found the 1965 Greater Burlington Urban Area Highway Plan document at the UVM library that showed a potential link between I-189 and the Burlington Beltline. That's the "more" part.



The Southern Connector/Champlain Parkway was a 1975 plan, with initial construction in 1981.
I added more to what I wrote on I-189 on AARoads at https://www.aaroads.com/guides/i-189-vt/

The roadway was proposed to be extended, as Alex noted.  But there is no indication (whether in the mentioned 1965 Burlington plan or in the research I've done at the state archives) that the extended roadway was going to be part of I-189.  In Vermont-speak, that basically means no.
