The improvements identified on this map are conceptual in nature and subject to change through the planning, environmental, and design process.
Roundabouts
Roundabouts are proposed at the following intersections:
-
Calico Basin
-
Red Rock Visitor Center Entrance
-
Red Rock Canyon Overlook
-
Red Rock Scenic Loop Exit
Parking and Trailhead
Parking and Trailhead improvements are proposed at:
-
Middle Oak Creek Trailhead
-
South Oak Creek Trailhead
-
First Oak Creek Trailhead
Traffic Signal
A traffic signal at the Sky Vista intersection is anticipated to be constructed in conjunction with Phase 1 of the Red Rock Legacy Trail in 2023.
​
Bike Lanes
SR 159 would include a designated bike lane with buffer from the travel lanes in each direction. Demonstrated below.
​
These improvements will be a coordinated effort between BLM and NDOT.
Roundabout Installation
The goal of the roundabout installation is to provide enhanced intersection
traffic control and safety by reducing vehicular speeds through roadway curvature when entering, driving through, and exiting the roundabout.
Safety
The installation of roundabouts along SR 159 will provide safer u-turn opportunities, while reduced speeds may decrease crash severity.
Pedestrian & Bicyclist Access
Pedestrian and bicyclist access through roundabouts will be evaluated caseby-case to provide efficient and safe travel through the intersection.
