I just realized it was an open-ended question. Maybe even before?
If we can leave the 17/69 interchange untouched in the meantime, I can see some possibilities:
(1) twinning SW Bypass bit by bit because a lot of cars actually hop on the bypass from Long Lake Road (Sudbury \80/) and head west
(2) twinning SE Bypass from 69 eastward until before the CN overhead, then realigning the 4 lanes farther east away from the current 6%(!) downgrade, then reverting the roadway to 2 SSM-bound lanes + 1 OTT-bound lane, and finally stop-gapping at Kingsway with a trumpet interchange (like 427 at Major MacKenzie Drive)
(3) extending the divided section around 69 a bit west of Long Lake Road but before access to cottages by Hannah Lake
Option (1) makes more sense traffic-wise, but adding service roads can be a pain in the butt.
Option (2) is a lot easier but the traffic’s probably lower than the SW section.
Option (3) assumes that most trucks are coming from 69 so extending the twinned portion westward by 1.5~2 km to cover Long Lake Road interchange will hopefully reduce driver’s frustration with leading (slow trucks). This is probably cheapest interim option among the (3). The current unprotected access to cottages by Hannah Lake is tricky though.
TBH I haven’t thought much about between Markstay and North Bay yet…
