We have a lot of bad bike lanes out here - lanes that end suddenly, lanes too close to parked cars, confusing markings...
We've also discussed it extensively on a local cycling forum. We've learned that traffic engineers do not generally have to have *any* cycling or pedestrian specific training to graduate.
Someone likely designed that lane thinking it was helping. It sounds like they found out it wasn't working well and tried to cludge together a fix that may have made it worse...
Personally I tend to not like bike lanes. I don't see enough really properly thought out ones and they tend to make motorists think you must travel in them (which is untrue in this state - though not every where). I prefer an unmarked wide lane or shoulder myself.
