Rocky Mountain National Park Proposes Increased Transponder Device Amenity Fee – Estes Park Trail-Gazette

Rocky Mountain National Park is seeking public comment on a proposed expanded $15 amenity fee to provide automated voluntary fast-passing gate transponders to interested visitors with valid annual or lifetime passes.

In 2004, Rocky Mountain National Park constructed an expressway at the entrance to Beaver Meadows, and in 2011 an additional expressway was installed at the entrance to Grand Lake. Rocky Mountain National Park is one of the only national parks to have a fast lane for visitors. Visitors who had purchased an annual pass or a lifetime pass could use their pass to operate the automated gate.

However, in 2019 the National Park Service changed the format for annual and lifetime passes. The new national passes are not compatible with the park’s existing rapid access gate system technology and the rapid access gate has not been operational for a few years. Based on this technological challenge, the park is proposing to switch to windshield transponders so that interested annual and lifetime pass holders can access the fast-pass lane, outside of the hours of the reservation system of entry permit timed by the pilot.

A transponder is a small device the size of a credit card that attaches to a vehicle window. Transponders are not removable or transferable and would work for at least one year or until the month an existing valid annual pass expires. If the park goes ahead with this proposal, the park expects to launch transponder sales in late spring 2023.
