John Monash: Engineering enterprise prior to WW1.

Wade Street Monier Arch Bridge, Bendigo.

Glancing view from the bank at deck level. The arch profile is badly distorted. The middle is almost flat and the near haunch has lost curvature. The prominent bluestone string course displays the sag. Above it is a red brick parapet wall with bluestone capping.

The arch of Wade St Bridge, Bendigo (1901) has become almost flat in the centre. Creep in the concrete is probably the major factor. (Note that consolidation and hence spreading of the foundations may have contributed. A further possibility is sag in the falsework during construction, though it was given an extra upward camber to compensate.)
