Route 8 was one of the original numbered highways in New Brunswick in the 1920s. The route changed little until bypasses were built on Fredericton's north side in 1982, between Renous and Newcastle in 1988, and between Bathurst and Allardville in 1990. The highway was extended south along the former Trans-Canada bypass of Fredericton in 2001. In November 2006, a two-lane bypass of a section of the former town of Newcastle opened between the Anderson Bridge (over the Northwest Miramichi River) and a junction with Route 430; providing easier access to the existing Route 117 bypass on the south side of the Miramichi River.
Boys In Red accident
On 12 January 2008, seven high school basketball players and a teacher were killed in an accident when their van collided with a tractor-trailer on Route 8 near the intersection with Route 11 exit into Bathurst. The tragedy drew statements of condolence from Prime Minister Stephen Harper and provincial premier Shawn Graham.
Marysville Bypass Construction
A bypass between the Fredericton suburb of Marysville and South Portage, north of Taymouth, completed construction and was officially opened August 26, 2014 which started in 2007 at an estimated cost of $124-million.
Until August 2014, this route stopped at Bridge Street in Marysville before reverting to a 2-lane local road and crossing to the west bank which it changes to Canada Street in Sandyville. This was a temporary solution as this section is under major construction projected to end 2015.
The road continues north following the Nashwaak River north to Nashwaak Village then continuing to Taymouth. From Taymouth, the road travels through Ross, Pleasant Valley and Nashwaak Bridge before leaving the Nashwaak Valley and climbed to the northeast passing through the community of South Portage and merged with the older portion of Route 8.
This section of this route was remunerated to Route 148 after the Bypass opened.
