Rabbit Hollow Bridge
Posted November 2, 2016, by Michael Quiet (mquiet [at] gmail [dot] com)

This little guy is in trouble:

https://natesupdates.wordpress.com/2016/11/01/rabbit-hollow-...

From the report it looks like corrosion of the concrete abutment and stringer pedestals has caused the deck stringers to no longer be supported by the abutment, with the truss handling all the load. Or how the state report eloquently explained it:

"The end of the deck and floorsystem at the northern abutment is now basically cantilevered off from the last floorbeam"

Being owned by the RR instead of the state might make it easier to replace, however this bridge is listed in the States historic truss bridge plan as a top tier candidate for its feasibility of rehabilitation as opposed to replacement.

I also found it odd that this problem cropped up so quickly, with both super and substructures earning a "fair" mark only 2 years ago. Looking at photos from the inspection back in 2012 we could already see section loss and pervasive rust at the abutments. A cautionary tale how a little preventative maintenance back then could have averted this situation now.
