The Denison Bridge - Bathurst
Bathurst became and still is the “gateway to the west” by road and the Denison Bridge is an important element of that history.
The Denison Bridge that you see today sitting high above the Macquarie River in Bathurst, New South Wales is actually the second Denison Bridge and in excellent condition for a bridge that carried the Great Western Highway over the Macquarie River for over 120 years. The Denison Bridge is now a heritage-listed footbridge, These days it is used by people out on there daily walk with their families or a fantastic spot to walk your dog as there is a footpath that circuits around the Macquarie River. The Denison is one of my favourite places to visit with my dog as you get an amazing view looking up and down the river as well as the Bathurst Show Grounds with some of the historic buildings being recently painted so they look fresh and vibrant again.
The Denison Bridge that you see today was completed in 1870, replacing an earlier bridge that was built in 1856 and destroyed in 1867 floods. It was designed by Gustavus Alphonse Morrell and built from 1869 to 1870 by P. N. Russell & Co.
In the early 1990s a realignment of the Great Western Highway resulted in the Evans Bridge replacing the Denison Bridge, with the latter converted to pedestrian traffic only. It was added to the New South Wales State Heritage Register on 1 August 2003, having earlier been listed on the now-defunct Register of the National Estate in 1978.

While searching for information on the Denison Bridge I came across a 52 page document to nominate the 1870 Denison Bridge Bathurst for a Historical Engineering Marker in November 1994. I have not seen any markers, plaques or signs on the bridge in reference to this document or the construction to the bridge.
Do you know where the sign is?
If you know where the sign is please comment below as I would like to find it. If the Denison Bridge was not approved for one do you believe it should have one?
As always please leave a comment below if I have any information incorrect so I can amend it or if there are any key factors I have missed that I should add to this blog post.
