1 Prepared For Mary Street Bridge 1894 Builder Unknown Township Route 439 over Reading Blue Mountain & Northern Railroad. Length Width Deck Width Project for Pennsylvania Transportation and Heritage 44' 13' 10 1/2" 13' 1/2" Weight Transportation: Trucks: 1 Actual lengths differ 3" from one side to the other - 44' 5 1/2" and 44' 8 1/2". Condition Lower chord problems throughout including severe packed rust causing rivet failure and section loss. Stringers, Floor Beams and Decking must be removed and replaced. Conduit attached to the bridge and power lines must be moved before removal of the span. Future Use Fairview Township will transfer the bridge to a responsible party for removal to a new location. The new owner will be responsible for moving and rehabilitating the bridge (as necessary for its intended purpose) and assuring its long term maintenance. Historic Value Rare example of a wrought iron built up lattice girder bridge in the U.S., built to cross over a railroad in Mountain Top, PA. Has evidence of a sidewalk attached which is no longer there but with two ornamental gates flanking either end on one side. Availability & Funding Details Bridge Marketed: 1/1/2009 Available Date: 2015 Funding: $ 53,000 Estimated Total: $ 120,254 The total does not reflect transportation or new location requirements. Assessment Mary Street Bridge is a rare style of bridge for the United States, more commonly found in Europe. This is a historically significant bridge not because these types have been demolished, but because only a couple were built on US soil, making it worthy of conducting a complete and correct historic restoration. After the removal of the truss from the site, the bottom chord will be removed by removing all the rivets and the deteriorated stringers, floor beams, and deck material, then we will shorten the depth of the trusses, as little as necessary, by cutting out the deteriorated portion of vertical lacing. The only other obvious work would be removal of the pack rust, and the removal and reinstalling the broken or missing rivets. Nels Raynor BACH SteeL For more information please contact: Kristina L. Thompson, PennDOT Architectural Historian, District krthompson@state.pa.gov. A final estimate will be required at time of purchase when location is defined with current market values calculated and or different engineers/contractors are selected. Prepared By:

2 Photo Gallery - Mary Street Bridge Site Visit - 8/15/2014 Mary Street - Built Up Web Lattice Bridge - Skewed ' x 13' wide at 5' high. The iron shows different signs of degradation - most likely related to continuous train traffic. Packed rust has impacted bottom chord, remains of an outrigger for a sidewalk and two decorative gates accompany this bridge. This is a rare example of a web lattice bridge in the U.S.

Three coat paint system is in dark, standard colors or a linseed oil finish where possible on iron surfaces. * Steel Picketed Rail, designed for 4" sphere guidelines or where rail exists. * Tension Cable Rail System is applied where historic railing is not present, placed outside original. * Transportation will require final estimates based as time of year, fuel, availability change.
