Plenty of other articles out there as well.
Seems like there are a lot of other civil engineers on the board (and other curious minds). I don't know if I completely buy how the tunnel will act like a bridge over the developing sinkholes, although neither geotecnical or structural are my specialities.
Anyone have an overunder on how long the routine "maintenance" will do the job. Looks like the anticipated 100 year lifespan of the tunnels is getting shorter and shorter.
