The Missouri Department of Transportation (MoDOT) began installing I-49 trailblazer signage (without shields) along with gantry signs and milemarkers, about 1200 signs in all, in February 2012. Signage bearing I-49 shields was covered or turned from view until the I-49 designation received final approval by FHWA. This includes milemarkers at intervals along the entire alignment apart from I-44.
