The original bridge was constructed in 1934, and a recent PennDOT project provided for the rehabilitation and painting of the massive truss structure.
In addition to the considerable amount of work improving the bridge, the new lighting installed also puts a nightly spotlight on the span.
While PennDOT estimates that 2,186 vehicles daily travel between Armstrong and Clarion counties, the night sees that figure greatly reduced.
Lights have been part of the site for years, but the addition of new LED lighting adds to the attraction.
Because the bridge takes State Route 368 over the Allegheny River in Perry Township of Clarion County and Parker City Borough in Armstrong County, the two counties share the costs of maintenance costs and utilities, and Armstrong takes the lead in administration.
The more powerful lighting had some people wondering if electric costs would also increase. The new lighting apparently uses less power than the old system.
“The replacement of the lights was part of the 2012 PennDOT renovation project, and it was decided to install LED lights as they are more economical,” said Agni Keller, Clarion County Chief Clerk.
In 2011, the total cost for power to the lights there was $1,006, which was split between the counties. For a period of 48 days between February and April, the total bill was $52.
“Clearly, the lights show a significant savings in ongoing utility expenses,” said Keller.
Work on the project also included the following:
-removal of existing guide rails
-removal of portion of existing bridge
-replacement of existing deteriorated or loose rivets with high strength bolts
-placement of reinforcement bars, existing modified deflection joint caulking
-cleaning existing scupper, drainpipes, and downspoutting
-cleaning, painting, and lubricating existing expansion rocker nest bearings
-painting existing and new structural steel using organic zinc-rich coating systems
-tack weld removal from tension members
-concrete bridge deck repair
-installation of new bridge structure
-application of pavement markings
-installation of guide rails and post mounted signs
-application of protective coating for reinforced concrete surfaces
-minimal approach work
-other related miscellaneous construction.
