My wife and I went out and road all the new bike lanes last week, road them again yesterday. Not because they are currently very practical, but to see how well they worked and to see what drivers reactions were. Also worth noting that I'm in that area on foot at least 3 times a week in addition to biking through a couple times a week.
I liked them. I liked them a lot and would struggle to come up with something better.
Generally, drivers have quickly figured out the bike lanes and parking areas. Like any paint change (see back in angled parking, one way streets, or any re stripping ever) , some will be slower to adapt than others. So there have been a few "oops" moments, but no more than the number of people I see accidentally turning the wrong way down a one way. And, luckily, given the way the lanes are done, the bikers are to the curb anyway. Even if there were no parked cars it would still be as safe as no bike-lane should someone choose to drive on the parking spaces.
I thought the way the lanes crossed under the freeway and the turn lanes was weird also. But it worked well. At some points the bikes have to cross right turning traffic - unless we are adding cycling overpasses there isn't a way to avoid it. The lanes cut over to the left and allow right turning traffic to pull to the curb a few car lengths before the actual turn. By doing so, cars that are waiting to turn right shouldn't see a cyclist come up behind them as they turn and both know ahead of time that the traffic crosses paths. It seemed to work well.
I like the green. It stands out. White means lanes you can cross. Yellow is for lines you shouldn't cross. Blue is for handicap. Red is a fire lane. Green is something different.
We also road the new bike lane on 3rd several times. Its also great, except it is less than a mile long. The entire length of 3rd from TU to downtown is a "share the road" and I've never seen it busy enough to justify 4 lanes of traffic and have seen no issues with the current 3 lane layout. I've also haven't had many issues riding it as a share the road, but that isn't most cyclists preference (I've never seen parents with kids on a share the road. Its almost always spandex jockeys). I hope they continue to expand that bike lane.
LINK THEM UP!
I hope they start linking all these up to something meaningful. Currently there is a bike lane from 11th almost to 3rd on Delware (past TU), then a few miles of no bike lane on 3rd, followed by almost a mile of bike lane, then no bike lane to downtown as you continue past the Midland valley trail at 444 (IDL eastern loop), no bike lane as you follow the share the road north on Greenwood...
To the north there is a half-butted bike lane along Greenwood to OSU Tulsa (a 3rd foot curb lane with no space for separation from traffic) to Pine and the Osage Trail (great trail by, unfortunately, I have recently heard of incidents of cyclists having issues).
If you turn west on Archer there is no bike lane until you hit a half-butt lane at Denver (> 3 foot curb lane no space for separation) which ends before you get ot the Katy Trail.
The new bike lanes don't hook up with any other bike trails or even share the road lanes and don't lead anywhere. You can basically go from Brady and Detroit, to John Hope Franklin (OSU Road), then into OSU's campus, or west to Boston, and to KOTV (stops on the other side of the street from "no riding bikes in our park" Guthrie Green).
I snapped a few photos to give a basic idea to anyone who hasn't seen them. Clearly could be improved on the photography department.
