This sign assembly for the Missouri 210-Missouri 269 interchange on northbound Missouri 269 (the latter route now decommissioned) showed that the markers for both routes used the rectangular "wide" style of sign. But different fonts were used, making the 210 seem bigger than the 269. The marker for Missouri 269 uses FWHA Series B, the usual standard in Missouri for three-digit state routes. The other marker was probably using Series C, possible because the digit 1 is much narrower than the others.
This photo was taken on northbound Missouri 269 in September 2008. Missouri 269 was decommissioned in 2012, with the city of Kansas City taking over the entire route as part of the Chouteau Parkway project.
