Heritage Bridge replacements in the Blue Mountains
This paper describes the replacements of Lillian’s Bridge and the Grand Canyon Creek 2 Bridge in the Blue Mountains National Park. These two bridges are important landmarks on the heritage walking tracks in the Blue Mountains and are used by thousands of hikers every year. Due to the high use and the aggressive environment over many years of service the bridges required replacement. The paper describes how the design processes undertaken to meet the heritage requirements for Lilian’s Bridge and how adaptive reuse of some of the original bridge parts has helped retain the character of these historic walking tracks along with a sympathetic combination of timber and steel. The paper also goes on to describe the construction methods used in such remote locations and the steps taken to create simple and effective bridge structures that were easy to construct in challenging environments. The bridges were helicopter delivered to site in several pre-assembled portions and once in place, put together by team workers abseiling from each bank of the canyon.
