Sometime next year, you may be able to ride a bike comfortably to the Red Rock Canyon National Conservation Area. Currently, you can only get there via the St. Route 159, which is heavily trafficked and not pleasant or safe for cyclists.
So the Bureau of Land Management and Federal Highway Administration are proposing to pave a multi-use trail away from the road outside Las Vegas, in Clark County, NV. The trail would run 5.5 miles from Charleston Boulevard and Sky Vista Drive in Summerlin to the Red Rock fee station.
The public can comment on the draft environmental assessment until May 9. The agencies intend to finish the project in summer 2023. Details: https://highways.dot.gov/federal-lands/projects/nv/red-rock
