Welcome to Rebuilding the Rust Belt. The inaugural post is Part 1 of a series in anticipation of next week’s Pro Walk Pro Bike Pro Place 2014 conference over 3.5 days in Pittsburgh, Pennsylvania.
During day 3’s City of Bridges Bicycle Tour, I’ll have the pleasure of showing off my home city’s bridges to bike/ped planning geeks from across the USA. The tour will highlight the good and bad of bicycle and pedestrian service on Pittsburgh’s river crossings. But because we will miss many other sites of interest (Pittsburgh has 446 bridges!), I’m supplementing the tour content in this series.
Wilksboro Avenue Footbridge
Constructed in the 1880’s, the bridge carried pedestrians (and presumably bikes as well) over a ravine, helping to connect the mostly residential area around Termon Avenue to California Avenue and to a school. After years of neglect (and an attempt to drive a VW Bug over the span) the bridge was closed, and remains so today.
The 407 ft long walkway is composed of a concrete deck on light steel framing, supported by kingpost trusses on steel bents – some as high as 120 ft – reaching eye level with surrounding treetops (dimensions, credit www.pghbridges.com). Foundations and abutments consist of stone masonry.
Surprisingly, the structure is in decent condition. My cursory inspection revealed intact steelwork with deteriorated paint. The most serious problem appears to be a crumbling south abutment. Otherwise, small miscellaneous repairs and a complete sandblasting and painting would effectively rehabilitate the bridge. (Some have quoted $800,000 to for a complete rehab, but I would expect it to cost more.)

Although the City had at one time been willing to spend $200,000 to demolish the Wilksboro Avenue Footbridge, it last stood that there is $400,000 set aside for repairs. Taking advantage of this historic preservation opportunity does not appear to be a priority for the City at this time. But, as delicate as the iron work may appear, we can expect this gem to hang on a few more years.
