Transportation Minister Geoff MacLellan says the government is aware of concerns from residents who travel along the 37-kilometre stretch that connects Antigonish and Sutherland's River.
Joe MacDonald, the volunteer fire chief in Barney's River, has started an online petition urging the government to twin that portion of the highway.
He says there have been 14 fatal crashes on that stretch since 2009.
MacLellan says a tender will be issued this week for the safety review.
