Route 176 is a 10-kilometre (6.2 mi)-long mostly north–south secondary highway in southwest New Brunswick, Canada.

Then, it runs southwest to the community of Justasons Corner.

The road then continues almost due south passing Cricket Cove.

From there, the highway changes names to Main Street as it enters the community of Blacks Harbour.

The highway ends at the Grand Manan ferry landing, which connects the route to Grand Manan and the town of North Head via Route 776.
