First noted on our 2015 Upper Midwest and Great Plains trip along I-29, and dating back to at least 2012 with the establishment of Interstate 49 in Missouri, MoDOT continues to replace Interstate highway shields with markers that omit the state name. Joining neighboring Arkansas and Iowa, the three states opted for signs with larger numerals (though Iowa’s version does not fully utilize the space where the state name once was). A trip to St. Louis last week (May 24) revealed a number of new assemblies, especially along Interstate 64 in St. Charles County.
