Heading east on 108ave there is a construction ahead sign, but no speed zone sign. There is a 30 sign placed off to the side facing the houses. Further along, there are multiple other signs that do not make any sense.

There are garbage bags over the 50 signs, but no alternate speed signs in place. Is 108ave 30km/h? With the volume of the photo enforcement around, the signage should be perfectly clear.
