A portion of River Road was permanently closed to traffic on July 26, 2023.

"The portion to be closed is northeast of the entrance to the Fort Lions Campground and southwest of 119 Street.
Turn arounds are in place at the closure points for personal vehicles to change directions and exit.
Commuters are to use 119 Street to access the industrial area.
The nearly two-kilometres portion of the road will be converted to a multi-use trail for cyclists and pedestrians."

Maybe use highway=proposed + proposed=cycleway + foot=designated + cycle=designated for the multi-use trail.
