|Here where I live there is a busy road near an elementary school and all the kids either walk or ride the sidewalk or ride on the shoulder/designated bike lane.
The road is four lanes with a double yellow and a speed limit of 45mph. The city engineers obviously regarded the childrens safety as prime importance so they installed concrete curbs on the roadway where the white line creates the shoulder or bike lane.
Now, this is a false sense of security because a car drifting over towards the bike lane will hit the curb and possibly pop over it into the bike area and not be as likely to get itself out again. It also creates a condition where debris builds up and never gets cleaned out. It's a good place to get punctures or find a huge obstacle where a bike has a decreased ability to maneuver around it.
This bad idea was given the go ahead because someone thought this curb would make school children safer. A concrete divider wall would be an answer, this curb actually makes the conditions more dangerous.

|They narrowed the car lanes on a road so they could add a 5 foot wide lane. There are no sidewalks on either side. Instead of using a curb they just lined up a row of concrete bumpers (the type used in parking lots). They've been hit and knocked out of alignment. They are broken and falling apart. To top it off, it's in a wooded area so it's just littered with fallen twigs, branches, and leaves.
It looks like crap and is completely useless.

|We've got one around here where the bike lane is west bound, but wide enough for two way bike traffic, and nothing at all on the eastbound direction. Very strange

|Recently the city put "calming devices" in some heavily used residential streets, to slow the traffic. They're like little concrete islands that jut into traffic, so the cars have to sort of slow down, get single file and slalom through.
Not a bad idea--wish I had some on MY street--but apparently nobody thought about bikes. The islands are just far enough from the curbs that you THINK you can ride through, but if you don't have the pedals exactly right, you can hook them on the concrete. There've been several falls, and riders have suddenly changed their minds and veered into traffic. The islands have tire tracks all over them, too, where people haven't seen them coming. And they're only a few inches high, so when we get snow on the roads....
