Travellers heading to Sudbury or coming out west will want to take the four-lane rather than Municipal Road 55.
Fifty-five has been closed between Koti Road and Bruno Street until at least late this morning.
The road is closed after a beaver dam burst yesterday flooding the road as a result.
Several homes in the vicinity have also had some flooding as a result.
The City of Greater Sudbury will be addressing the issue this morning.
