|Route outline (key)|
The M8 was a motorway along the Lagan Valley that was proposed in 1964. Its purpose was to distribute traffic heading from Lisburn to Belfast, taking traffic heading to North Down and East Belfast off of the M1 before the M11 traffic from Newry and northern Lisburn merged in.
Detailed plans never existed, as the plan was short-lived. It had gone by 1969 due to poor traffic estimates and the removal of the highly-disruptive M4 section north of Stranmillis.
