The Regional Transportation District says the transportation hub, which is planned to be finished in the spring of 2014 will integrate bus, light rail and passenger rail services all from the more than 100-year-old building.
"This is going to be a completely new place when people see it in the spring of 2014," Daria Serna from RTD told 9NEWS.
Over the next few months, RTD and Amtrak will relocate some of their lines from Union Station to other points in the city.
On Feb. 1, Amtrak trains that left from Union Station will be relocated to a temporary station at 1800 21st St. behind Coors Field near the intersection of 21st and Wewatta Streets. Amtrak will move back to the newly renovated Union Station in 2014.
Also on Feb. 1, the pedestrian tunnel that linked the light rail platform to Wynkoop Street will permanently close. RTD says pedestrians should use the 16th Street Mall Ride or the sidewalk on 16th Street to get to and from the platform.
RTD says bus lines that picked up and dropped off passengers at Gates B, C and D at Union Station will now have their first and last stops at the Market Street Station after Feb. 9.
