It’s been a long time coming, but it’s finally here! The biggest thing coming to Denver deserves a big celebration. Join RTD on Friday, April 22 for the grand opening ceremony of the new University of Colorado A Line at Denver International Airport at 10 a.m. To commemorate the historic event, Governor Hickenlooper and other special guests will preside over a special ribbon cutting ceremony, dedication, color guard and the start of FREE rides on the University of Colorado A Line all day after the ceremony — from noon to 9 p.m. And that’s not all! On Saturday, April 23, the fun continues with community-hosted station parties along the University of Colorado A Line from 10 a.m. to 2 p.m. Enjoy a day filled with food, entertainment, giveaways and activities for the whole family. Best of all, they’re providing FREE rides on the entire rail system. (Note: The A Line will be FREE from 5 a.m. to 10 p.m. on Saturday.) Be one of the first to ride the train to the plane…all aboard! (Starting Sunday, April 24, the RTD’s new line from Union Station to Denver International Airport will officially be open for service.)
