|March 2011 (-43.534 Degrees, 172.628 Degrees) Hospital Bridge|
A photo of the Hospital Bridge that was taken in 1912 is available online at the Christchurch Library Archives. It looks very similar to the current Hospital Footbridge, except for the deck and railing. Perhaps they were able to reuse the existing steel truss arch and just replace the deck.
