Notes and History
ME 89, a minor highway in the Aroostock/Caribou region and a service route
for the former Limestone Air Force Base (later Loring AFB, decommissioned
1994), does not appear until 1946-7.
Originally as designated, it terminated in Limestone
(what was then ME 165, and is now US 1A) at the same place as today, but
only extended west to ME 223, entirely along new routing,
and ME 223 then continued the alignment west
into Caribou. In 1953, ME 223 was truncated at ME 89 and ME 89 took the
old alignment to Caribou.
Curiously, ME 89 continues past present-US 1 to terminate at
ME 161 on Main St. This is because US 1 used to run on Main St, and the
routing has not been corrected to terminate it early along the eastern bypass
alignment (see US 1 for the history of its routing).
The entire ME 89 routing is sterilely referred to as the Access Hwy today,
evoking images of boring corporate civil engineering meetings in the heads
of all who intone the name for all eternity.
