Nova Scotia Highway 103

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 1998, construction was completed that twinned a five kilometer section of highway between exit 2 and exit 3.[2] In November 2006, construction was completed that twinned 15 kilometres of highway between exit 3 and exit 5.[3] In December 2006, an 8.3 kilometre bypass around Barrington was completed.[4]

In late September 2015 a new section of highway was opened to bypass the Port Joli area.[5] In November 2016, a new section was completed which bypassed Port Mouton. Residents complained that the single exit east of the community had lengthened the trip for people heading west from Port Mouton.

The new interchange in Ingramport (exit 5A) opened in January 2017.

Work on twinning Highway 103 from exit 5 (Tantallon) to exit 5A (Ingramport) began in February, 2018 and was completed in December, 2020. Twinning from exit 5A (Ingramport) to exit 6 (Hubbards) started in 2020 with an expected completion date of late 2023.

Between 2006 and 2009, there were 29 deaths on the highway.[6] In 2009, it was considered Nova Scotia's deadliest highway and was ranked the second most dangerous highway in Canada by the Canadian Automobile Association.[7][8] In 2009 alone, ten people died in automobile accidents on the highway, according to the Nova Scotia Department of Transportation and Infrastructure Renewal.[9] Between 2008 and 2012, there were 22 fatalities on the highway.[10]

In September 2018, local residents raised concern over the presence of a road sign on the highway, near the turnoff to Port Mouton, that had a very confusing appearance, looking like a patchwork of several other road signs. It was supposedly revealed when a hotel removed its billboard advertisement, revealing the sign below.[11]
