Update:

A section of the Trans-Canada Highway east of Mattawa remains closed due to a washout and it has forced a long detour. 

There is no estimate for when the section from Bissett Creek to Deep River might reopen.

People driving to and from Ottawa have been forced to detour via Highway 60 through Algonquin Park.
