As part of our long-term transportation planning effort, we intend to manage traffic congestion within the park while maintaining and improving public access. This action is supported by our 2006 Transportation Implementation Plan and Environmental Assessment (email us to request a copy), and Executive Order 13514 on Federal Leadership In Environmental, Energy, and Economic Performance (2009), which requires agencies to measure, manage, and reduce greenhouse gas emissions toward agency-defined targets including a 30 percent reduction in vehicle fleet petroleum use by 2020.

From 2006 to 2016, visitation increased from 833,049 to 1,585,718, an increase of 90 percent in 10 years. Arches also averages around 2,000 commercial bus tours a year with the busiest seasons from May through October. With this increase of visitation, we have seen an increase in parking issues that are no longer associated with holidays, weekends, or other special occasions. Parking congestion is now the norm from mid-March through early November.

Congestion Management Study

As part of our long-term transportation planning efforts, we initiated an Alternative Transportation System and Congestion Management Study in 2011 to find a means to reduce traffic congestion, air and noise pollution, greenhouse gas emissions, and the impacts of transportation on the park's valuable resources. The study aimed to achieve this reduction by decreasing the number of automobiles within the park while maintaining and improving public access and visitor experience. The study included both a shuttle alternative and non-shuttle alternatives to meet these goals.


Although it may seem that the shuttle would be the solution, planners determined that several factors would lessen the effectiveness of a shuttle. The length of the park's road system—a total of 52 miles—and the distance between several key areas in the park were significant barriers to a shuttle's success. Because of these factors, planners concluded that in a best-case scenario, shuttles would result in a reduction of 23-28 percent of cars, require one-way travel times up to one hour and 20 minutes, and would require $2-3 million to operate during a five-month season under a service contract. This cost does not include purchasing and maintaining the 14 buses required to provide the service.

Planners also looked at the shuttle operations at Zion, Bryce Canyon, and Rocky Mountain national parks and noted that although visitors enjoyed this option, the pulses of 40 or more visitors dropped off at a trail all at once was causing significant resource damage and more crowding on the trails.



We are looking at other congestion management solutions and strategies to alleviate traffic congestion, protect park resources, and provide a better visitor experience.


We completed planning newsletters in July 2015 and October 2015.

Traffic Congestion Management Plan

We released a proposed Traffic Congestion Management Plan (TCMP) on November 1, 2017, to address vehicle traffic and parking congestion problems that affect visitor access, visitor enjoyment, and resource conditions. Read more about the TCMP.
