You didn't specify which end, the other end of Langford Parkway connects to Sooke Road.
All you have to do is take a short drive on Veterans and turn left at Kelly road to connect to Sooke Road.
I'm pretty sure they won't put a road through the cemetery although I guess the residents wouldn't complain.
We’d never build new roads if we operated with the mindset that all we had to do was take a short drive via other roads
Langford Parkway does not connect to Sooke Road on either end, but running it east would make sense. Whether or not that happens, though.
