Almost daily, I see commercial vehicles like tractor trailers traveling through 82nd Ave residential area. The street from 49th st to the railroad tracks is posted for no trucks. However tractor trailers drive this area of road to get to the commercial businesses near the railroad tracks. Just because the construction is for a city building doesn't make them exempt. The large vehicles cannot make the turn from 49th onto 82nd without disrupting the flow of traffic. This is a nuisance and needs to be monitored, otherwise we are wasting time and money posting those signs if we don't enforce our rules.
