From what I find on the internet, it meets the definition of a cycle track. From
bicyclinginfo.org:
"Cycle tracks, also known as sidepaths, are separated bicycle facilities that run alongside a roadway. Unlike bike lanes, cycle tracks are typically separated from automobile traffic by a physical barrier, such as parked cars, bollards, a landscaped buffer, or a curb. Cycle tracks may be one-way running with traffic, one-way running against traffic, two-way on the same side of the road, or two-way on both sides of the road."
And from what looks like a pretty comprehensive PDF document about cycle tracks at
AltaPlanning.com:
"A cycle track is an exclusive bicycle facility that combines the user experience of a separated path with the on-street infrastructure of a conventional bike lane. Cycle tracks have different forms, but all share common elements. Cycle tracks provide space that is intended to be exclusively or primarily for bicycles, and are separated from vehicle travel lanes, parking lanes and sidewalks. Cycle tracks can be either one-way or two-way, on one or both sides of a street, and are separated from vehicles and pedestrians by pavement markings or coloring, bollards, curbs/medians or a combination of these elements."
But rather than splitting hairs over a technical definition, this new bike facility on Bannock is a nice improvement and, along with all the new and proposed bike lanes in downtown, plus additional (and much needed) better signage, we are making good progress in Denver.
