The Mulligan Highway is a state highway in Queensland, Australia. It runs for approximately 270 km between Mareeba and Cooktown, on the east coast of Cape York Peninsula where it terminates.Named after bushman James Venture Mulligan the sealed highway follows the old Cooktown Developmental Road and was completed in 2006. Since it was sealed, travelling time from Cairns to Cooktown has reduced from 6 to 3½ hours.
