You got movie tickets! A long time ago (13 years) the production database was irrecoverable! I got backups working just a week before tolling finally started. Failure of that system would ultimately result in the tollway becoming a freeway (allowing for buffering of data at the gantries, etc. etc.)
Although I had some responsibility for the tunnel safety systems at the time, we never touched them knowing that any problems would result in the road being closed.
From what I remember, the gantries were (at the time, a few years ago) able to store about 2 weeks' worth of traffic before tolls would effectively become free.
