University of Colorado A Line and B Line service disruption

Commuter rail service on the Regional Transportation District (RTD)’s University of Colorado A Line and B Line will be disrupted for 48 hours this weekend by construction work on the Central Park Boulevard Bridge, the North Metro N Line and signal testing. This 2-day service disruption begins 3:00 a.m. Saturday, September 29th, and goes through 3:00 a.m. Monday, October 1st.

Bus shuttles will be provided.

To lessen impact to riders, RTD contractors Regional Rail Partners (RRP) and Denver Transit Partners (DTP) and City and County of Denver contractor Park Creek Metropolitan District coordinated construction and testing to take place during the same weekend.

Train riders should allot about an hour of additional travel time between Union Station and Denver Airport Station and an additional 30 to 45 minutes between Union Station and Westminster Station.

During the service disruption – which will take place from 3 a.m. Saturday through 3 a.m. Monday – the University of Colorado A Line and B Line will be powered down due to high voltage and proximity to construction crews. Bus shuttles will serve passengers in place of rail service at all stations along both rail lines.

Bus shuttle schedules are as follows:
