Progressive Railroading, 5/4/15:
Denver RTD's 'R Line' more than half complete
Denver's Regional Transportation District (RTD) announced last week that the I-225 "R Line" light-rail project in Aurora, Colo., is now about 60 percent complete.
The project's contractor Kiewit Infrastructure Co. marked the progress with RTD and Aurora city officials on April 30.
The full story is here.
Again, the R line will be a suburb-to-suburb line that will not serve downtown Denver at all. It will be an extension further into Aurora of the existing H line that now ends at Nine Mile. But it will take the southeastern connection where it meets the Southeast Line, and turn south with the E and F lines to the Lincoln terminus, and then the three will eventually be further extended south from there.
