Rock Blvd. got a new treatment last year that included a few bike lanes. It is a nice upgrade allowing users who need access to areas south of the river to jump off the river trail and cross the river via the Rock Blvd. bridge (rather than continuing on out to McCarren Ave.). Specifically, this is the area of improvement.
All and all, it really is an improvement with designated and marked bike lanes replacing what used to be just a wide shoulder. However, the lane on both sides terminates at the entrance to Rock Park and the line striping leaves a little to be desired.
If you look at the photos below you might notice the current line stripping has a sharp jog right after the entrance to the park. An inattentive motorist (or one talking, texting, or looking for a dropped ipod) might continue straight on and end up cruising right down the bike lane!
I see what they were going for....a nice smooth entrance for the new and improved bus stop. I just don't want the guy in the over sized pickup sharing the bike lane with me when he doesn't intend to! So if you use this new section, keep an eye out for tailgaters or the vehicle persuasion!
