Secondary Highway 670 Shield

  Western Terminus:  Junction Highway 638 north of Bruce Mines.

Eastern Terminus:  Dunn's Valley

Length:  9.5km

Multiplexes:  None

Orientation: East-West

Regions Served: Algoma District

AADT (2008):  80, for the entire length of Highway 670.

Road Info: Highway 670 is unpaved for its entire length.  A sign warning of rough road conditions for the entire length of the highway was posted at either end of the road, though when I travelled the road early in September of 2012, the road had been freshly graded, and was fairly smooth for a gravel road.  The speed limit is posted at 80km/h, but there are several unmarked curves where such a speed would be unsafe.  Highway 670 is fairly tame compared to other Algoma secondary highways, however at times the highway still veers in unexpected directions with little warning.  The Dunn's Valley area is a particularly pretty part of the province, and is worth a visit, particularly in the late summer or early fall.
