PEACH SPRINGS, AZ - The road that leads to the Grand Canyon Skywalk might not be suitable for travel much longer.
The Hualapai Tribe says it expects to bid out a project this month to finish paving Diamond Bar Road.
The old ranch road twists around Joshua trees, dips into a local wash and ends up on the Hualapai reservation, west of Grand Canyon National Park.
Mohave County has maintained the 9-mile unpaved, gravel section using a motor grader and water truck.
The tribe says the paving project should take 15 months once it chooses a contractor. Previous estimates have put the cost at $30 million.
The Skywalk is a horseshoe-shaped glass bridge that extends 70 feet from the canyon's edge on the reservation in northwestern Arizona.
