Due to the recent flash floods that Alberta experienced there a a couple of know problems in the Turner Valley / Black Diamond area.
EDIT: The road on Highway 22 west of Black diamond has been repaired and is now passable.
The bridge at the south end of Turner Valley on Decalta Drive has a section gone and will be impassable for the foreseeable future. This is the one by the old gas plant.
To get south you must currently cross the river through Okotoks before heading west and south, noting that travel through the town of High River is not possible at this time, and for the foreseeable future
. Stay on highway 2 south past high river, or go west between Okotoks and High River on Hwy 7 , before going south on highway 22.
EDIT: You can now travel through High River on the main roads.
Highway 40 between the Trans Canada and the trunk road junction in the south has had major damage
and multiple bridge washout/ failures as well as significant roadbed erosion and slides. After seeing aerial shots, I wouldn't count on using it this summer at all.
Hwy 66 past Bragg creek is expected to remain closed from the Elbow River Bridge (just past the McLean Creek Turnoff) indefinately due to severe damage, cutting off access to Powderface trail from the east end. I suspect that Powderface trail suffered significant damage as well but as yet have not seen any pictures or reports. Anyone who knows that route, knows how many areas have likely been damaged or completely destroyed !
EDIT: As of August 6th the highway past McLean Creek OHV area (highway 66) is accessible via a temporary one lane bridge (controlled by lights).
Powderface is still officially closed and has barricades at the east end and a gate and barricades at the west end. There are new bridges (5 or 6) along its length and many slumps that have yet to be repaired. Narrow but passable for bikes.
The bridge at Ram Falls is now open to traffic .
Some if not all campgrounds have suffered significant damage in Kananaskis country and some may not be open this season either. Be sure to check with the Alberta websites before planning on camping in that area.
As of October 27th the 940 south of Hwy. 40 is passable with one minor water crossing. It is good to 532, which is also passable and in fairly good condition out to Hwy 22.
Both of the above are still barricaded as "road closed" while repairs continue.
