PORTLAND, OREGON-  Mail order truss  bridge- truss bridges with welded connections that are assembled at the company but taken to its final destination for installment as a pedestrian crossing- seems to be the norm nowadays. While they are easy to build and cost effective, they lack the aesthetic taste that should be characteristic for its surroundings.

Yet it does not mean you need to scrap the plan altogether. Used truss bridges- namely historic bridges that are more than 60 years old- can fit the mold, and they usually tie in together with its surroundings because of their design and appearance. The Portland Waterworks Bridge spanning the Sandy River at Dodge Park in Clackamas County, Oregon is one of those unique bridges that once fit this mold.

Built in 1893, the bridge was a product of the Bullen Bridge Company of Pueblo, Colorado and was erected under the direction of Charles Loweth. It was deemed as the oldest historic bridge that served its original function in the state of Oregon, as it carried the Bull Water Pipeline Conduits 2 and 4, two of the important conduits that provide water to a quarter of the state’s population.  For over 80 years, this Pennsylvania petit through truss bridge with Howe portal bracing (with ornamental features) and pinned connections ran parallel to the Lusted Road Bridge, another Pennsylvania Petit through truss bridge that carries vehicular traffic.

Since 2010 the Portland Waterworks has been in storage waiting for reuse somewhere else as a pedestrian bridge. After the two conduits were laid underground, running underneath the Sandy River, the bridge was rendered obsolete and was later dismantled, leaving the Lusted Road Bridge as the only historic bridge left to be seen as part of the Dodge Park complex.

The Portland Waterworks Bureau (PWB) and the Oregon State Historic Preservation Office (SHPO) are working together to give the bridge away to a known party that is willing to use it for recreational use. As the bridge is eligible for listing on the National Register of Historic Places, the bridge must not be destroyed or used for anything other than as a pedestrian crossing, even if the length of the bridge is 300 feet, very unusual for a Pennsylvania truss bridge built small enough to be used as a pedestrian or bike bridge. The deck width is 14 feet.  The PWB and SHPO has a handbook guide with information about the bridge, how it is assembled and its historic significance, just to name a few items. They can be found on the PWB website by clicking here.  Any party interested in the bridge will receive the structure in parts (as seen in the picture), making it easier to haul, plus some information on how to reassemble the truss bridge at its new location. Yet additional help in terms of funding for the relocation of the bridge as well as expertise from the historic bridge and preservation communities are available upon request.

If you are interested in purchasing the Portland Waterworks Bridge for reuse as a recreational bridge, please contact Kevin Larson of the Engineering Services Group. The contact information can be found on the same website by clicking here.  The Bridgehunter’s Chronicles will keep you up to date as to when and where the Portland Waterworks Bridge will find its new home. It is possible that it could find a new home inside Oregon- a plus for many preservationists living in the state as well as those interested in seeing it reused again. Yet as has been seen in many cases, the Waterworks Bridge may end up out of state, like in Colorado, where a party in interested in bringing in bridges for recreational use. More on that in the Chronicles as the information comes in.
