Drivers and some boaters can expect some delays at the O'Rorke Bridge the next two days.
Maintenance will be performed on the draw bridge both days between 9am and 3pm, with traffic reduced to one lane today and tomorrow.
Crews from the New York State Department of Transportation will be sealing the bridge deck to keep water out of the machinery rooms.
The bridge cannot be lifted for a period of one hour after the sealer is put in place.
The County says boaters who use the river and marinas in the area should make alternate plans today and tomorrow.
