The Walnut Lane bridge over Wissahickon Creek in Philadelphia will be closed and detoured for five months starting Friday night, April 1 to replace the existing deteriorated concrete deck and sidewalks, the Pennsylvania Department of Transportation (PennDOT) today announced. The bridge is expected to reopen in early September.
During the bridge closure, Walnut Lane through traffic will be detoured over Wissahickon Avenue, Midvale Avenue, and Henry Avenue. One sidewalk will remain open on the bridge for pedestrian travel during construction.
This work is part of PennDOT’s $14.7 million project to rehabilitate the historic Walnut Lane Bridge. Construction began in November 2015 to improve the bridge by removing the existing bridge deck and replacing it with a new concrete deck. The plan also includes replacing the existing sidewalk, sidewalk supports and balustrade railing; repairing the support abutments and piers with formed concrete to match the architectural line and texture of the existing abutments and piers; maintaining the existing plaque at the southwest corner of the bridge; and replacing the damaged plaque at the northeast corner with a replica plaque. The contractor also is installing new tear-drop street lights, and removing the existing temporary structure under the bridge over Forbidden Drive.
The improvement plan also includes the reconstruction of the existing roundabout on Walnut Lane at the intersection of Park Line Drive to enhance travel and safety. The contractor will resurface the roundabout approaches; install new sidewalks; install curb ramps; reconstruct and landscape the center island; relocate a water main and inlets; and install new fire hydrants.
The six-span Walnut Lane bridge was built in 1907. The concrete arch structure is 565 feet long and 60 feet wide. It carries 16,810 vehicles a day.
Buckley and Company, Inc. of Philadelphia is the general contractor on the $14,769,654 contractor which is funded with 100 percent federal funds. The project is expected to finish in August 2017.
