Nova Scotia Highway 111
Highway 111 is a controlled-access highway in Halifax Regional Municipality, Nova Scotia, Canada.

The highway runs from Pleasant Street in the neighbourhood of Woodside in the south to the A. Murray MacKay Bridge in the north.
History
Construction and development
Construction of the Circumferential Highway began in 1960. It originally ran from Pleasant Street in Woodside to Woodland Avenue. The section from Woodland Avenue to the MacKay Bridge was constructed at the same time as the bridge, opening in 1970.Exit 4 was completed in 1971 with the opening of Highway 118.
The grade-separated interchange with Portland Street was completed during the 1977/78 fiscal year. The interchange with Burnside Drive was completed during the 1980/81 fiscal year. The Mount Hope Avenue interchange was completed in 2006 at a cost of around $11.5 million.
Micmac Rotary
The Micmac Rotary was a traffic circle located at the intersection of Hwy 111 with Route 318 and Trunk 7. It was named after nearby Lake Micmac, which was partially in-filled to accommodate it. The Micmac Rotary was notorious for rush hour congestion, even resulting in the recording of a song entitled "Mic Mac Rotary Blues".The rotary was removed during a redesign of the intersection in the late 1980s which saw it replaced by the "Micmac Parclo", which consists of a series of overpasses and controlled access lanes. The resulting roadway through the Parclo and across Lake Micmac to the interchange with Highway 118 is the widest in Atlantic Canada at 10-12 lanes.
