The same sinkhole scene at Mission north of the Excelsior bridge some days later. The hole has widened to cover most of another lane, and SFDPW's cordon has expanded to cover that. There are more traffic cones around because the lane closure has been lengthened in both directions of traffic. The sack of concrete is still in the hole for whatever reason.

   @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.
