deconstruct can not select liquid pipe bridge

check your deconstruct is set to the correct setting, if you set it to wires it will only deconstruct wires

Some argue that a bridge is a kind of wire/pipe/vent (just avoiding an intersection and no further purpose) and should be deconstructable with the same mechanic as the wire/pipe/vent on the respective overlay for convenience.

I also have this issue. I've tried deleting the bridge with every available deconstruct option to no avail. It's so troublesome that I generally try to avoid the bridge if at all possible because I know it won't delete.
