Denver, Colorado.
The R Line began service yesterday (February 24).
The line is 22 miles long and consists of 16 stations; 8 stations are new.
The R Line only serves the suburbs of Denver: Aurora, Centennial, Greenwood Village and Lone Tree. Only one station serves Denver (proper); Belleview.
The H Line was also extended from Nine Mile to Florida.
A 3 station extension further south into Lone Tree is currently under construction; opening is planned for 2019.
