Bridge closed to traffic October 2010; replacement being considered which may or may not include preservation: http://www.pottsmerc.com/general-news/20150308/montgomery-co...

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: 'The 8 span, 720'-long rivet-connected steel Warren (with verticals) pony truss bridge, built in 1935, is supported on stone piers and abutments with concrete caps. The truss members are rolled sections, and the bottom chords are composed of channel sections. Rolled floorbeams and stringers support the concrete deck. Angle section railings are fixed in front of the railings, and a metal railing with cast posts along the sidewalk. Although a large example, the bridge is not historically or technologically significant because it is a late and standard application of riveted Warren truss bridge technology.'

Just read an article in yesterdays paper about this bridge.Closed 9 years ago as a structurally deficient bridge,this span is not set to open until 2022.The $20 million project will involve reconstruction of the bridge.The project is taking more than a dozen years to complete because it is listed in the National Register of Historic Places.This honor translates into having hurdles including environmental surveys before a project can begin.A team of planners presented an update on the project on 5-22-19 at Montgomery County Community College-Pottstown which is several blocks from the bridge.According to one of the planners the environmental process took 6 years which I take as it's completed.The planners unveiled the latest preliminary proposal which is expected to be complete at the end of 2019.The final design plans will take another year and a half.Construction is set to begin in the spring of 2021 and take at least a year.The proposed bridge will have a pedestrian walkway along with the inbound lane to Pottstown wide enough also for bikes.The plan calls for replacing the existing alignment of the 749-foot-long bridge with a five-span concrete beam structure.The plan also calls for two 11-foot traffic lanes,two 4-foot shoulders and a 6-foot-wide sidewalk on the eastern side which I mentioned earlier.Improvements will also be made to the intersection on the Pottstown side of the bridge which is located in Montgomery County.This includes a new traffic signal and a turn lane onto Industrial Boulevard for better traffic flow.

As per an article printed in the Reading Eagle on 6/14/17 plans for demolition and replacement of this bridge are still on schedule.Engineering for the bridge project should be finished by the end of this year or early 2018.The design phase will be finished by the end of 2019 and construction should begin in 2020.

As per an article printed in the Reading Eagle on 2-19-17 this bridge will not be rehabilitated.According to this article Montgomery officials approved a $20 million project to demolish and rebuild this bridge which is to start in 2019.The design of the new bridge is expected to be finished this year.The funding for this project is 80% federal,15% state and 5% funded by both Montgomery and Chester counties.I do have this article if anybody has any questions.

As per an article printed in the Reading Eagle on 5-8-16 a new bridge is in the planning stages and this bridge will be replaced by 2020.It has been a decade since the bridge was last used.Federal funding is available for the new bridge.The alternative analysis period has ended and now the preliminary engineering period has started.Construction should start in 2019 and take about a year and a half.Montgomery County has earmarked $25 million for the bridge as part of the Regional Transportation Improvement Program.This bridge has been offered for sale to both Pottstown and North Coventry Township who didn't want it.Other options looked at were never implimented.If a new owner is not found for the bridge it will be demolished.Any more news i get will be printed here.

this article was taken from the reading eagle dated 4-5-2015.as per the article engineering and design plans will begin this year.the engineering phase will determine whether the county will repair,replace or demolish this bridge in favor of a new bridge that realigns keim street.montgomery county will cover 60% of the engineering costs and chester county will cover the remaining 40%the actual work I feel will not begin for quite awhile yet.if anybody does hear of any additional information on this bridge please let me know because I am from that area being Montgomery county not far from Pottstown.thanks.

here is the latest news on this bridge courtesy of the reading eagle dated 3-15-15.5 years and this bridge still faces an uncertain future.if the bridge is replaced with a new span,neither Pottstown or n.coventry township want it.pottstown nor n.Coventry want the bridge because of the cost of maintain basically a pedestrian bridge which they could not fit in their budgets.montgomery and chester counties have not made a decision on the future of this bridge which could be either repair,demolition or replacing the bridge.as of now this is the most current news I have.any future news I receive will be posted here.

This historic bridge is in a Section 106 Review. It is one of those mystery projects where they start Section 106, then go a long time without any further movement. As a consulting party, I sent comments in over a year ago to a Rehab Feasibility Analysis, but have never got a response, nor has Section 106 moved forward beyond that point. Not sure what the problem is. Anyway, no construction can take place until Section 106 is concluded. Morevoer, additional design work will be needed after Section 106. So its going to be awhile before any actual project begins.

the reading eagle newspaper just printed an article concerning this now closed bridge.before it can be possibly replaced studies including threatened turtles must be completed.this bridge will probably get replaced around 2018 at the earliest according to the reading eagle.so it looks like this bridge in the meantime will continue to be closed to traffic.if anyone needs information on this i do have the article.

This bridge replaced the Wooden Covered bridge that was once across the Schuylkill River at this spot. The bridge is own by the two counties.

This bridge has been condemned. Neither Pottstown nor North Coventry want to pay for it's replacement.
