The Heysen Tunnels are twin tube road tunnels which carry the Adelaide-Crafers Highway under Eagle On The Hill in the Mount Lofty Ranges in South Australia. The tunnels were excavated using a tunnelling machine normally used in heavy-duty mining operations which tunnelled through 500 metres of rock for each tunnel at an average rate of 3 metres per day.[1] The tunnels were completed in 1998 and officially opened in May 2000. Each tunnel carries 3 lanes of traffic.

The tunnels are named after artist Sir Hans Heysen.
