Road is in great condition anything with moderate clearance will get in. 2nd bridge has new planks. Don't drive a dump truck on it, but it'll hold any standard vehicle no problem.
Drove to the Marvel Pass trailhead (KM 6) without any issues in a Subaru Legacy. New wooden treads have been installed on the second bridge (KM 4) just before the Assiniboine Lake trailhead - big improvement.
Managed in 2WD low clearance to parking at ~4.5km. Bridge decking is deteriorating and a few small water bars are present. Walked the last 1km to 5.5km due to modest water bars that could be overcome with moderate clearance.
