ROAD SIGNS OF MINNESOTA

Updated March 17, 2002

INTERSTATE SIGNS

(May 2000) Duluth, MN. Current style interstate sign without "MINNESOTA".

(May 2000) Moorhead, MN. Interstate signs with "MINNESOTA" are longer being erected, but are not that scarce right now.

US HIGHWAY SIGNS

(May 2000) St. Louis Co., MN. Current style US highway and state trunk route signs.

Embossed US highway sign. Note the small "N" suffix. In the early days of US highway numbering, AASHTO used many split routes (10N and 10S for example). In the 1930's, AASHTO began phasing out many of these split routes, but some still exist primarily in Kentucky and Tennessee. US-10N was phased out by 1937 as it does not appear in the 1937 Minnesota Official Highway Map (Collection of Robert Edgar).

Later style US shield. These were probably used during the 1960's and early 1970's. US-371 was decommissioned in Minnesota in 1972 according to the Official Highway Map. (Photo by Joe Koehler)

STATE TRUNK HIGHWAY SIGNS

Current Minnesota trunk highway sign. I've heard that this style of Minnesota sign was phased in around 1967 (My Collection).

Older style trunk highway sign used between 1954 and the late 1960's. These reflective signs are probably the first to utilize Scotchlite sheeting which was invented by 3M in Minnesota. (Photo by Joe Koehler)

Older style embossed sign used from the 1940's until the mid-1950's. According to official highway maps, these signs were phased out during 1954-56. (Photo by Joe Koehler).

Another embossed MN highway sign. This sign uses the original black on yellow colors that were probably phased out during the 40's as yellow was reserved for warning signs. (Collection of Robert Edgar).

(May 2000) St. Cloud, MN. Minnesota and US signs on an overhead gantry outside St. Cloud.

COUNTY HIGHWAY SIGNS

(May 2000) outside Duluth, MN. County route marker still used by many counties.

(May 2000) St. Louis Co, MN. County route markers on big green sign. Note the generic use of the word "COUNTY" as opposed to a county name.

(June 2000) Eden Prairie, MN. Newer pentagonal county sign used in some counties on overhead gantry. As with the older sign, this county route marker only uses the word "COUNTY" on big green signs.
