As per an article printed in the Reading Eagle on 7/23/17 work began Monday on a replacement bridge and detours will be in effect for months,possibly through October.Representatives from Plenary Walsh earlier this year said it would be 15 weeks of construction on this bridge so they are going to be cutting it close for completion of this project.The lane width on the new bridge will be 11 feet,slightly wider than the current 10-foot span.This bridge is part of PennDOT's Rapid Bridge Replacement Project,which is set to replace 558 structurally deficient bridges over a 3 year period.The state project carries an estimated $899 million price tag.The individual price for the Grosstown Road span was not specific.Plenary Walsh Keystone Partners,a consortium of construction,design and engineering firms,is tasked with finance,design,construction and 25 year maintenance of the bridge.

I believe Nathan was sorting out confusion from dialogue started by Myself and George. Nathan has more bridge knowledge than most and ALWAYS welcome his comments. Thanks for all the fish!

I will let Nathan speak for himself, but I believe that he was quoting the PennDot assessment.

So what Nathan is saying in his disdainful comment "Boring, blase, COMMONPLACE!" george oakley is not to pull an Arthur Dent and put yourself in front of the bulldozer for this bridge. Don't risk your life man! But Nathan can be a bit gruff at times in his replies - the Grumpy Cat of Bridgehunters.

Yeah, 1880 and Stringer don't generally go together in the same sentence.

Likely there was an 1880 truss at this location that was replaced by the current structure in 1932.

I have no idea what article you are talking about but this bridge was most certainly not built in 1880. Featuring a standard balustrade railing, the 1932 date given in the National Bridge Inventory is accurate. What is inaccurate in the NBI is the bridge type (its a steel stringer encased in concrete) This is a common problem one must be on the lookout for in Pennsylvania mostly in this period. Here is the bridge description from the Historic Bridge Inventory:

The 3 span, 125'-long encased steel stringer bridge, built in 1932, is supported on a horizontally scored concrete substructure. It has standard concrete balustrades on each side of the concrete deck. The bottom flanges are exposed, and concrete diaphragms are the full depth of the stringer encasement. Concrete encasement was favored in the state because it provided protection for the steel and eliminated the need to periodically paint the beams. A representative example of one of the most common, mid-20th century bridge types and designs in the state, it has no innovative or distinguishing details. It is one of over 639.
