Multnomah County has installed a series of speed bumps (a.k.a. rumble strips) on SE Madison Ave as it approaches the Hawthorne Bridge (westbound). The bumps are aimed at reducing bicycling speeds as riders transition from the on-street bike lane up a ramp to the shared sidewalk which also happens to be the location of a TriMet bus stop. This bike lane is slightly downhill and bike speeds are relatively high.
There are five bumps placed about two feet apart and they’re made up of thermoplastic strips about an eighth-of-an-inch think. That might not seem very high, but on a bicycle the bumps can definitely be felt — especially for riders with narrow tires. We’ve heard a lot of feedback so far that not only are the bumps jarring but many people swerve into the adjacent vehicle lane to avoid them.
The bike lane on SE Madison St. as it approaches the Hawthorne Bridge just got a three-foot buffer this morning. This is one of a trio of projects coming to the east and westbound approaches that we can expect in the next few months as part of a joint effort by Multnomah County (they own/manage the bridge) and the Portland Bureau of Transportation (PBOT) to improve bike access.
This first phase has added a three-foot buffer to the existing six-foot wide bikeway on Madison west of SE Grand Ave. According to the County, the new striping, “will provide greater separation for westbound bicyclists and motor vehicles on the popular bike bridge.”
