They suck and are poorly designed and not maintained so not usable in many places.
They added 200 ft of bike lane both directions that END at the intersection. Ending at intersections is a pretty common theme in GA despite it clearly stating in the drivers manuals that changing lanes IN an intersection is illegal.
There is so much gravel pebbles on the bridges left from winter they are not ride able. I am seeing the same brake pads in one intersection as I saw the first time I commuted by bike 2 years ago.
I went to a commissioners meeting and introduced myself as a bicycle commuter and then asked what it would take to get the lanes removed since they are not being swept and designed poorly and endanger my life more so then if I was left to ride in the lane. The guy was shocked.
