After the concrete piers of the former Arch Street Bridge were brought down during an explosive demolition, work on the bridge project continues toward its scheduled May completion date.
"The contractor needs to excavate the concrete rubble from the piers that were demolished and he will use conventional demolition techniques to remove the existing abutments," said Jay Miller, state Department of Transportation assistant construction engineer.
Seven spans of the bridge were brought down beforehand at two separate times. The first three spans were demolished in November, while the last four were taken down earlier this month.
The state Department of Transportation’s multi-year DuBoistown Bridge replacement project is wrapping up with blasts this past week that will allow the remaining piers that supported the old bridge to be removed.
Other than moving debris from the site, work around the area still needs to be completed before May.
"The river bank areas at the existing abutment locations require grading and rock-slope protection and the causeway has to be removed from the river," Miller said.
The contractor also has to perform some paving and restore a parking lot for Susquehanna State Park. "Minor" landscaping also is required in the area and will be done in the spring.
Miller said that there was no damage or effect on the river during any part of demolition. He noted that the state Department of Environmental Protection and the
Fish and Boat Commission were present at each demolition.
When disposing of the former bridge's materials after demolition, Miller said what could be, was recycled. The bridge's steel was sent to a local recycling center, according to Miller.
Pier materials were being used in several different capacities.
"The concrete rubble from the piers will be disposed at an approved waste area.
The reinforcement from the piers will be recycled and the rock from the causeway is being reused as fill for a local private construction project," Miller said.
The remaining rock is the property of the contractor, according to the contract, and either will be used by them or sold.
The new DuBoistown Street Bridge was opened in mid-November. It officially will be named the Lance Cpl. Abram L. Howard Bridge at a sign-unveiling ceremony in early April, according to the office of state Rep. Rick Mirabito, D-Williamsport.
