Route 1 serves several towns and communities along the southern shore of Prince Edward Island, as well as bypassing the provincial capital, Charlottetown. The route begins at an intersection in Borden-Carleton at the northern end of the Confederation Bridge (the bridge itself and its approach roads are unnumbered federal roads). The bridge crosses the Northumberland Strait to New Brunswick, where the highway becomes New Brunswick Route 16. Travelling eastward, a spur route, Route 1A, branches north towards Summerside. The highway continues meandering east through the communities of Crapaud and Bonshaw, and bypasses Clyde River and Cornwall before crossing the waterway dividing the North River and Graham Rogers Lake into Charlottetown.[2]
On May 17, 2010, construction began on upgrades to the Charlottetown Perimeter Highway.[3]
This work was completed later that year on October 15.[4]
Route 1 was then transferred from its old routing along University Avenue and Grafton Street onto the new highway.
A proposal to realign Route 1 through Strathgartney Provincial Park west of Charlottetown was met with significant public opposition in 2011.[5] Construction started on a revised route avoiding the park, dubbed Plan B by opponents, in October 2012. Environmentalists protesting at the work site caused construction to be halted for several days.[6] Darcie Lanthier, then interim leader of the P.E.I. Green Party, was arrested[7] and several protesters charged with trespassing before construction resumed. The realignment opened to traffic on September 23, 2013.[8] The protest group, which became known as Stop Plan B, monitored construction throughout the project and returned in October 2015 to plant trees along the new alignment.[9]
Route 1 on the Cornwall Perimeter Highway
On September 6, 2016, construction began on the Cornwall Perimeter Highway, a new alignment bypassing the town of Cornwall to the north.[10][11] Construction was mostly complete and the new bypass opened to traffic on October 1, 2019.[12] Upon its opening, the former alignment was renumbered Route 27. The town plans to develop the former arterial highway into a commercial thoroughfare and community hub.[13]
