Project Information:

This project involves the rehabilitation of the Freeport Bridge carrying Traffic Route 356 over the Allegheny River, ConRail Tracks, Township Road 784, S.R. 2019 and Buffalo Creek. The bridge consists of 29 northbound spans and 24 southbound spans. The bridge features a three-span continuous steel deck truss unit with spans of 310, 452, and 311 feet over the Allegheny River. The south approach has five spans consisting of single span steel multi-girders and the north approach has 21 northbound spans and 16 southbound spans, all consisting of single span steel multi-girders. The bridge was built in 1962 and the project length is 3,700 feet. The roadway width on the structure is 54 feet and the out-to-out width is 63 feet which includes a 5-foot sidewalk and four lanes of traffic.

As a result of both recent and the Year 2006 NBIS Inspections by Modjeski and Masters, Inc. PennDOT decided that the Freeport Bridge and adjacent Buffalo Creek Bridge needed to be posted for a live load limit of 3 tons.  This reduction in live load capacity was deemed necessary because of widespread severe section loss and corrosion to the approach girder webs, to the girder bearing column metalwork, and to the top and bottom flanges of the floor beams of the three span truss across the Allegheny River. School buses and some emergency service vehicles were affected by this posting.  

August 02, 2006 PennDOT requested that Modjeski and Masters, Inc. prepare Contract Documents for emergency repairs in order that those 14 spans normally used by school busses could be repaired by September 29, 2006.  A Contract that upon completion would allow the posting to be removed from both the spans used by school busses and the remaining 40 spans of this bridge was delivered to PennDOT on August 15, 2006.  The Contract was awarded on August 22, and the Contractor began repair activities on the 14 spans used by school busses on August 28, 2006.
