State Sen. Chris Romer plans to introduce a bill today that would take a portion of higher vehicle registration fees and flow the money to a special district that would coordinate financing, construction and operation of a streetcar line on Colfax Avenue in Denver and Aurora, The Denver Post reports. “It’s been a dream of mine to restore streetcars to Colfax; they change the way people live,” said the 50-year-old Romer, D-Denver, who grew up not far from the area’s longest street.
