US Route 11, from the railroad underpass in Canton to Market Street in Potsdam, is about to undergo several weeks of repaving work.
The New York State Department of Transportation says the work is expected to begin Wednesday with milling, followed by resurfacing, which is expected to begin about Aug. 27.
Motorists will encounter alternating one-way traffic controlled by flaggers and should expect minor delays.
Motorists will encounter grooved pavement and should exercise caution in the work zone, DOT said.
All the work is expected to be completed by early September.
