Eeek -- on top of an injured lady -- beyond this, this is serious enough that the teamway might be closed for a few days. Minimum. Out of safety necessity, unless it was definitively traced to a one-off debris.
But the
photograph shows crumbling concrete was what hit the woman --
So therefore, procedure dictates a sustained engineering / structural analysis, because being a crumble, it is not a confirmed one-off event (e.g. falling wrench accident).
This may require a sustained closure of Bay West Teamway for engineering analysis
This will make for a very chaotic Friday commute.
Since Bay West Teamway is currently the temporary stand-in for the Bay Concourse.
If not safety-confirmed on time for the evening commute, redirecting the crowd away from the Bay Teamway is going to create some quite massive chaos of biblical proportions on the first day. Unless they can quickly confidently localize the crumbling area and fence off only that corner. (e.g. section of unrenovated concrete area)
(Luckily I'm telecommuting tomorrow.)
