The University of Colorado A-Line to Denver International Airport is expecting slight delays on Monday morning and into midday, RTD says.
Regional Transportation District officials say the delay stems from earlier crossing maintenance at Quebec Street after a truck damaged a crossing gate arm. Trains were running 20-30 minutes behind schedule earlier in the day.
CU A line Update: Gates at Quebec crossing are repaired and trains are running 15 min departures, slight delays over the next hour possible.

At DIA, airport operators say passengers should expect a very busy morning on Monday.
