|Route outline (key)|
When the new Glasgow and Edinburgh road was built in the 1920s, opening as the A89, it bisected the old B805, and it appears that when the new road was renumbered as the A8 in 1935, the old B805 was downgraded.
Today its route follows Hallhill Road as far as the new A8, where it is broken by new development, explaining the "other" Hallhill Road to the east, also part of the route. After then running along Springcroft Avenue, it becomes Rhindmuir Road before again being lost under Baillieston Interchange. The original eastern terminus of the road no longer exists.
