^ Hawthorne is perhaps one of the most bicycle unfriendly streets in the whole city! While the bridge is great, its suicide on the east side. There are no bike lanes there and there have been numerous bicycle accidents and fatalities over the years along the street.
Most bicycle friendly streets?
-NW 18th ave - HUGE bike lane along it.
-Interstate Ave
-Belmont
-Mississippi
-7th ave through the central eastside
-Alberta
-10th/11th/12th through downtown - traffic is quite slow and easy to keep up with, but avoid the trolley tracks! I've even seen bike cops crash on them.
then there are all the lesser-used streets in Portland. Since we're on a grid, there are usually 20 ways to get from one place to another, unless you are traveling halfway across the metro area. For instance, the city has designated a huge number of '
bicycle boulevards' - some of which ban through auto traffic - and mark it with bike signs.
examples:
SE Ankeny, Clinton, Lincoln, and quite a few others.
