Travelers heading to and from the airport Saturday should prepare for shuttle service in place of the A Line, which is receiving maintenance on the I-70 bridge near Peña Boulevard.
The line will run normally between Union Station and Central Park, while buses will run between Central Park and the airport. The maintenance will run between 2:30 a.m. and 6:30 p.m.
RTD says travelers should plan in extra time for shuttle transfers. The first continuous train from the airport will leave at 6:30 p.m. and from Union Station at 7:27 p.m.
