This bridge exhibits the more common design features of the County's stone bridges -- parapets with rounded top and horizontal curves at the portals.
This bridge is listed as stone arch bridge S-2 in the Pennsylvania Historical and Museum Commission survey of PennDOT bridges which have significant historical value. The structure is described as "segmental arch of high quality rock, faced ashlar construction; voussoirs dressed; parapet finished with curved course." The survey entry reports the date as 1901.
The 1876 Hopkins map shows the saw and grist mill of Joseph Cochran on Lick Run just upstream from this bridge. The mill race -- the water diverted from the stream to power the mill -- ran to the west of the stream, through the mill near the western end of the bridge site.
Nellie Bly (Elizabeth Jane "Pink" Cochran) was born at Cochran's Mill in 1864. She was the thirteenth of the fifteen children of Judge Michael Cochran. She overcame a troubled childhood to be a pioneer in journalism and gained fame by, among other things, embarking on a journey to break the record of the fictional Phileas T. Fogg's feat in "Around the World in 80 Days."
This bridge may be threatened with replacement. A 1997 PA Senate Bill (186 P.N. 445) lists an appropriation for $215,000. (Base Construction Allocation - $150,000); (Land Allocation - $5,000); (Design and Contingencies - $60,000).
The ownership of the bridge is not clear from the signs posted nearby. Small white markers, typical of PennDOT's secondary roads, indicate the bridge is part of SR3015. But a green sign claims "Allegheny County Maintenance Begins Here" to indicate that the bridge may be part of County Road 5045, aka Cochran's Mill Rd. The Senate Bill lists it as a Local Bridge as opposed to State.
