Got to check something off my UCLA bucket list today - I got to join a tour of the tunnel system! The tunnels are primarily for utilities - power, steam, water, phone, data, etc. I'm sure all big universities have tunnels like this, but our facilities department actually offers guided tours, partly as a way to discourage people from breaking in and touring on their own. It was a very fun and humid experience.
