The New England Interstate System in Maine (1925)
The New England Interstate system was a mutually agreed-upon system of
marking interstate and intrastate highways determined by the six New England
states (that is, Maine, New Hampshire, Vermont, Massachusetts, Connecticut
and Rhode Island), and to a lesser extent New York state east of the Hudson
River.
Instead of the pole highway marking
system that preceded it, the NEIs were actually numbered highways, with
routes under 100 carrying the interstate links and routes 100 and above being
local intrastate routes, on the 11" x 15"
yellow and black signs seen at right (the
white border is for illustration and was not part of the sign itself).
Many of these routes were in fact descended from the
pole highways and auto trails; see
Maine's Pole Highways for their
lineage.
These numbers completely replaced the former system of
lettered highways.
Despite the New England Interstate system being inaugurated early in 1922,
and almost certainly with input from the Maine State Highway Commission,
the routes in Maine did not actually become signed and known to the public
until 1925. However, some early maps listed the already-determined routings,
with some of these maps dating back as early as 1923 despite little or no
official physical signage in the field. Understandably, there is some
argument in early maps about routings, particularly for NEI 1, NEI 18,
NEI 20 and NEI 24. On the 1923 Rand McNally auto trails map, NEI 20 is seen
starting in Portland and going to Gray, Auburn, Monmouth, Augusta, Belgrade,
Rome, Mercer, Norridgewock and finally up its final 1925 routing from there
(see below) to Canada via Anson and Bingham; NEI 18 is seen considerably
further south of its later routing as US 302, following a routing through
Baldwin, Standish and Hiram back to Fryeburg very much like that of
modern ME 113. For its part, NEI 24 was on a
considerably different routing, running from Brunswick to Gardiner, Augusta,
Vassalboro, Clinton, Pittsfield, Newport, Corinna, Dover-Foxcroft, Guilford,
Monson and terminating in Greenville.
Just a year later, however, NEI 20 and 24 took over their final routings but
1 was shifted to an inland route, leaving the coast at Portland and passing
through Lewiston, Augusta, Newport and finally picking up the 1923 and 1925
routing in Bangor; NEI 18 is on the modern US 302 corridor.
Interestingly, the 1924 map shows ME 100 signed on the
coast on what was NEI 1 just the year before. Although these routings are
interesting for conjecture, they are ultimately an academic point as the only
official routings were those in 1925 as listed below.
New England Interstate Route 1 (NEI 1)
- Definition
- Enters the State at Kittery, thence via Wells, Biddeford, Portland,
Brunswick, Bath, Rockland, Belfast, Bangor, Ellsworth, Columbia Falls,
Machias, Calais, and on into the Province of New Brunswick.

and US 1AB.
New England Interstate Route 9 (NEI 9)
- Definition
- Enters the State at Berwick, thence via North Berwick to Wells,
intersecting Route 1.
- Length
- 17.0 miles
- Replaced by
- ME 9
New England Interstate Route 11 (NEI 11)
- Definition
- Enters the State in the town of Lebanon (opposite East Rochester, N.H.),
thence via Sanford and Alfred to Biddeford, intersecting Route 1.
- Length
- 31.3 miles
- Replaced by
- ME 11, except Sanford-Alfred, which is US 202/ME 4A, and
Alfred-Biddeford, which is ME 111.
New England Interstate Route 15 (NEI 15)

- Enters the State at Gilead, thence via Bethel, Rumford, Dixfield, Wilton,
Farmington, New Sharon, Mercer, Norridgewock, Skowhegan, Pittsfield, Newport,
Bangor, Old Town, Lincoln, Mattawamkeag, Island Falls, Houlton, and on into
the Province of New Brunswick.
- Length
- 296.2 miles
- Replaced by
- US 2, except Pittsfield, which is partially
ME 100 and partially decommissioned (see
US 2), and Orono-Old Town, which is
US 2A.
New England Interstate Route 18 (NEI 18)
- Definition
- The Theodore Roosevelt International Highway, entering the State at
Fryeburg, thence via Brigton, Naples and Raymond to Portland.
- Length
- 60.6 miles
- Replaced by
- ME 18 (now US 302).
New England Interstate Route 20 (NEI 20)
- Definition
- The Interstate Quebec route, intersecting Route 1 at Brunswick, thence via
Richmond Corner, Gardiner, Augusta, Waterville, Skowhegan, Norridgewock,
Madison, Solon, Bingham, Jackman and on to Quebec. This route coincides with
Route 15 between Skowhegan and Norridgewock.

is now US 201A.
New England Interstate Route 24 (NEI 24)

except Mars Hill-Easton, which is now
US 1A, and Easton-Presque Isle, which is now
ME 10.
Some 1923-4 maps do show the routing between Fort Kent and Madawaska as part of
NEI 24, but this does not seem to have been recognized on the 1925 state map.
