It's a bidirectional bike path adjacent to the one way (east bound) East Cliff Drive between 41st Avenue and 32nd Avenue. There's currently construction underway to rebuild portions of the roadway and bikeway that have been lost to bluff erosion. The road and bike path remain open during construction, but construction equipment is often parked in the middle of the path like this while crews take their lunch breaks.
At first I was a little bit annoyed -- a front loader would never be parked in the middle of a street adjacent to a road project, after all -- but the reason construction equipment would never be parked over a traffic lane is because cars can't easily maneuver around obstructions, where cyclists can handle it with little problem. I had to leave the bike path and go into oncoming traffic, but really it's not that big of a deal.
What do you think? Would you get annoyed at an intrusion like this?
Kinda related: It's legal to park in bike lanes in California, just in case you didn't know. My little town has a local ordinance that prohibits street parking in most bike lanes, and several other California cities do the same thing, so it might be moot.
Update: Here's a photo Murph took of an obstructed bike path in
