History
Route 126 was commissioned in 1965 to replace the former route 33. It was shortened in Miramichi in 1997 to end at the new Route 117 bypass, rerouted in the Lutes Mountain area in 1998 to follow a short section of the former Trans-Canada Highway (Route 2), and shortened in Moncton in 2003 when the portion of Mountain Road south of Wheeler Boulevard (Route 15) was turned over to city control.
Guide
Most of Route 126 is straight and crosses over relatively flat land. It parallels the New Brunswick East Coast Railway directly to the east.
