DENVER (KDVR) – UPDATE, March 14, 6:15 p.m.: RTD tweeted Sunday evening that bus and rail service will be suspended for the night at 7 p.m.

Rail service is expected to continue with significant delays.

UPDATE, March 14, 2 p.m.: RTD tweeted Sunday afternoon that, due to blizzard conditions, all bus and rail operations are operating at significant delays. All travel is discouraged at this time unless it is critical.

ORIGINAL: Buses are delayed 15 to 30 minutes, but the Light Rail system is not being affected as of Sunday morning by the massive snowstorm hitting the Denver metro area.

Laurie Huff, an RTD spokesperson, told FOX31 that riders need to plan ahead and dress in layers if they anticipate using public transportation.

If there are any route cancellations, Huff said, rider alerts are going out to those impacted. RTD is also taking precautions to keep Light Rail power lines clear of ice, ensure bus riders can be picked up if a bus gets stuck in the snow, and keep passenger pickup platforms clear of ice and snow so riders don’t slip and fall.
