You may have noticed the above markings were installed in the City of Glendale on N Range Line Road. You may be wondering, "What is that?!?"
That is a sharrow. Sharrows are pavement markings that improve cycling safety on streets that are too narrow for traditional bike lanes. These markings indicate to drivers that the road is a preferred bicycle route, and that they should be prepared to share the road with cyclists. The placement of the sharrow shows cyclists where they can ride to avoid traveling in the door zone of parked cars.
