FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The single span, 186'-long, pin-connected, double intersection Pratt (or Whipple) thru truss bridge built in 1889 is supported on ashlar abutments. The bridge has eye bar lower chords and built-up upper chords of standard metal sections. The eye bar diagonals extend across two panels. U-shaped hangers carry rolled section floorbeams, steel stringers, and an open grid deck placed in 1950. It has double-loop floorbeam hangers in the end panels, a detail associated with Wrought Iron Bridge Co. bridges. It has lattice portals with builders plaques and medallions with the "1889" date. Original railings have been replaced by welded channel railings (ca. 1950). W-beam guide railings have been placed to the inside of the channel railings (ca. 1980). The survey has identified fewer than 10 pre-1890 Whipple truss bridges. This is one of two complete examples in York County (the other is BMS# 66 4017 0030 0000, built in 1884), both fabricated by the Wrought Iron Bridge Co., one of the nation's leading late-19th-century metal bridge builders. The bridge is a historically and technologically significant example of its type/design.

Conewago Creek Bridge

Oh, that's right PennDOT, I give you an award and you show me up by actually restoring an historic bridge! Well maybe I'm just a cynic, but your track record would say that this is just an isolated event. So I'm going to issue a challenge to you for the coming year....start restoring your landmark spans for the glory and respect they deserve.....and just maybe you will start to realize that you are doing the right thing!

No fellow Pontists......I haven't been drinking (yet). I'm just trying to grasp something positive for the coming year, and there's no better place to start than with the HOPE that some of our biggest adversaries will seek a change in their agendas. I know it's a tall order......but why not aim high!

I hope everyone out there has a safe and happy new year! And may all your endeavors be successful for the coming year......and beyond!
