I'm sure this can be blamed on cars somehow.

@carraway that is s sinkhole.

Frankly, rather lucky the pavement failed quickly. Gets scary when it keeps pavement keeps it structure for a a while.

It looks like they have made safe and are waiting for the other utilities to mark USAs. The area has been marked out in white but no one had marked.

@sewblue Made sort of safe, anyway. SFDPW closed one lane on the northbound side (far side in that photo), but left both southbound lanes open. At the time I passed it the first time the hole had already widened to the point where cars' tires were audibly thunking against the far side of the hole in the inner southbound lane, or swerving into the outer one.

Passed by again a few days later and they'd been back to extend the closure across that lane too, either before or after the collapse widened further.

There's sewer piping staged nearby and notices of impending parking restrictions but I haven't followed that work closely enough to know whether part of the work caused the hole, was a response to the hole, or a response to the state of the sewer which made the hole more likely.

@carraway sewers can create holes on their own, especially with water leaks.

In the case above, the NY city kept fixing the pavement without bothering to look into why it kept sinking. The sewer system had a break and was creating a void. Eventually the void created enough pressure on the surrounding pipes a gas line cracked. Migrated to a building.and killed 8 people.

Make safe includes stopping people or cars fom falling in or getting in harms way. It doesn't mean fixing. That they have widened the area without fixing is concerning.

I am surprised this hasn't been fixed yet.
