Rail Fare Zone Map
The RTD rail system is divided into four fare zones: A, B, C, and Airport. Rail fares are based on how many fare zones you travel in during your trip. Travel in one or two zones is a Local fare, travel in three zones is a Regional fare, and any trip originating or ending in the Airport zone is an Airport fare.
Stations
The RTD Board of Directors authorized a 2.3-mile extension of the existing Southeast Rail Line In July 2014. Southeast Denver business associations, companies and municipalities joined forces to support the new light rail line. The City of Lone Tree and area stakeholders contributed an unprecedented $25 million, with an additional $3 million of in-kind contributions, land and right-of-way.
The local match of approximately 12 percent of the project cost far exceeded the 2.5 percent match RTD asked of its local partners, and helped RTD successfully secure federal funding for the project. RTD received $92 million from the Federal Transit Administration Small Starts funding program, as well as $9.4 million from Congestion Mitigation and Air Quality grant funds. The total cost of the project is $233.1 million.
