Fourth Street Bridge
Posted January 10, 2010, by Nathan Holth (form3 [at] historicbridges [dot] org)

Nice to see some photos and info for this beautiful, preserved historic bridge. This bridge's preservation project has been condemned by Canadian engineers in Victoria, BC who are trying to justify the pointless replacement of Johnson Street Bridge http://www.historicbridges.org/britishcolumbia/johnson/index.php. They claim the preservation of this bridge was a waste of money because it went over-budget. I disagree, and from what I can see this bridge will now provide decades of reliable service as a functional and beautiful historic landmark.

Interesting bridge, with plenty of history. The concrete mass looks real, although it's not. Newly rehabilitated.. looks good. Wish I had a chance to see it open.
