Which State?

Lack of state name on Interstate route shield in Joplin, Mo.

Up to the dedication of Interstate 49 in December 2012, Missouri always included the state name in standalone shields (i.e., not a part of other signs such as a "big green sign"). But it appears that most Interstate 49 shields don't have the state name, such as these photographed by Matt Roberds in Joplin the day of the I-49 dedication. This assembly is on 32nd Street at Interstate 49 and US 71.
