Did you know there was an old railway tunnel just near the Old Guv building in King William Road?
Well there was!
As far as I know it was built in 1886 to service the old Exhibition Building and the Exhibition Oval near Kintore Avenue.
My grandfather Cyril used to tell me that there was a tunnel under King William Road which continued on from the Adelaide Railway Station to the Exhibition Oval.
They held the Royal Adelaide Show there in the late 19th Century as well as some international sporting events.
The Royal Adelaide Showgrounds was later transferred to its current position at Wayville.
