Temporary signage by Utah Transit Agency

Corrugated plastic sign from the UTA (Utah Transit Agency) outlining service improvements on the 21 Bus line


And service reductions as a result of reduced ridership demand in response to shelter in place/stay at home orders wrt the coronavirus.

The corrugated plastic signs are probably easier to affix and remain more permanent, compared to laminated paper flyers.  As a result, they are easier to read. 

(I never got good photographs, but the service improvements were also promoted in the digital route sign information displayed on bus fronts.)
