With the start of light rail service in December 2008, these color-coded designations were retired. The Red Line was eliminated altogether as most of the route is now covered by the light rail line (with several portions, including Metrocenter Mall, now also covered by Route 15-15th Avenue); the Blue Line was renamed to Route 39 – 40th Street and now terminates at the intersection of Camelback Road and Central Avenue; the Green Line was renamed Route 29 – Thomas (its original pre-ValTrans name); its routing remains unchanged.
