Seems like MAYBE when disrupting a thoroughfare on a weekday one MIGHT wish to post a notice a few days in advance so that folks don't miss appointments and wreck vehicles?
Communication, communication, communication ...... please consider this for the balance of the road improvement projects .... and the message board is not the best way.
Contact the neighborhood watches in the area - they are the most effective at spreading the word. If you need contact info I can give it to you - we'll be happy to assist in keeping the public informed.
I hope the new road is fantastic and I look forward to trying it out soon.
