Bridge Documentation

This bridge no longer exists!

This historic bridge has been demolished!

This bridge is a rare example of a truss bridge dating to a historic period and consisting of traditional riveted construction that was built for pedestrian use only. Most surviving truss bridges are bridges that were designed for vehicular use. As such, this bridge is quite interesting to view. The trusses are light weight, and the vertical clearance is low enough most people can touch the portal bracing.

The bridge has an unusual "second end post" which extends beyond the top chord at a higher angle and then makes a right angle to connect with the deck. This all occurs with a normal end post present as well, heading directly to the deck from the top chord at the usual angle.

The bridge leads nowhere today. It once likely had additional spans that led the walkway across the railroad tracks and provided access to the homes on the top of the hill.

This is a historic bridge that could be preserved in place, however it might also be a good candidate for relocation and re-use elsewhere, perhaps in a park setting.

The bridge passes over the McArdle Roadway Viaduct.


This bridge is tagged with the following special condition(s): Footbridge
