bridge closed

About one year ago, almost to the day, a truck with a hydraulic lift plowed into the Sitterly Road overpass in Clifton Park. The road has been closed on and off for a year but now to actually replace the bridge and road, Sitterly Road will be closed all week.

I live on the Cohoes side of the Cohoes Waterford Bridge and I understand that it needs to be replaced. I don't understand, however, why they have to shut down the entire area for every weekend in July.
