Apparently the reason the tunnels were closed was that Transurban could not operate the emergency sprinkler system and smoke extraction fans. Surely it would have been cheaper for Transurban to pay a few MFB fire trucks to be stationed outside the tunnels and close a lane to guarantee them access in case of an emergency. That way traffic could flow, tolls could be charged, and nobody would be as upset. I am sure Transurban make more than the fire brigade would charge them per hour.
