Highway 103 is an east-west highway in Nova Scotia that runs from Halifax to Yarmouth.
The highway follows a route of 294 km (183 mi) along the province's South Shore region fronting the Atlantic coast. The route parallels its predecessor, local Trunk 3. The highway varies from 2-lane controlled access to 2-lane local secondary roads on the section between Yarmouth and Hebbville. East of Hebbville to Upper Tantallon, the highway is 2-lane controlled access, with the exception of a short 4-lane divided freeway near Chester. From Upper Tantallon (Exit 5), to the interchange with Highway 102 (near Bayers Lake) in Halifax, the highway is 4-lane divided freeway.
In 2013, Highway 103 was redesignated as the Fishermen's Memorial Highway.
The highway has developed sporadically since the 1970s, with the 2-lane controlled access portion to Bridgewater being largely responsible for the abandonment of CN Rail's South Shore line, the former Halifax and Southwestern Railway. In November 2006, construction was completed that twinned 15 kilometers of highway between Exit 3 and Exit 5.
