Too Many 44's to Keep Distinct

One of the signs on this gantry on westbound Interstate 44 in St. Robert is incorrect. While through traffic indeed would be destined for Springfield, the green business-loop shield on the left sign is wrong.

Also strange is the use of the up arrow for through traffic.
