Rock ‘N’ Roll marathon likely to snarl some Denver traffic

DENVER -- The Denver Rock 'N' Roll Marathon took over the streets of Denver Sunday, causing a headache for some drivers.

An interactive map outlined the road closures, highlighted alternate routes and provided access information for popular destinations which were affected by road closures during the race.

At most points along the course, pedestrians and bicyclists may cross the course during safe gaps in runners.

Traffic controllers were present along the race to keep roads moving as smoothly as possible.
