With the reroute of BC-1 to the south of town onto a new 4-lane alignment, the 'southern' end of the Business route has changed locations, as the old JCT has been completely removed.
This would require a 'closed' point & a new point on both BC-1 & BC-1 Bus.
However, on the Business route, I would also include a 3rd point,
@ Frontage/Chase, as the old route of BC-1 was using that up till sometime between Oct '21/Sept '22.
