Eight Southern End spans are among 31 to be replaced in the next two years.
Five will be done between June and November of this year. The others will be replaced in 2017.
"We expect to have specific start dates within a month," said Dan Galvin, a spokesman for Plenary Walsh Keystone Partners. Plenary Walsh is overseeing the projects, which are part of Pennsylvania's rapid bridge replacement project.
The stone arch that carries the Low Grade Rail Trail over Pumping Station Rd. is inching closer to demolition.
"PennDOT, Norfolk Southern, and Eden Township have made progress in complying with the PUC order to remove the bridge," PennDOT spokesman Gregory Penny said last month, "… but there are still a few last-minute details that need to be addressed."
PennDOT is in no hurry to repair or replace eight of the 10 bridges whose weight limits were lowered last fall.
PennDOT reduced the weight limits on the bridges during a dispute between Governor Tom Corbett's administration and the state House of Representatives over transportation funding. At the time, PennDOT justified the new, lower weight limits as an effort to maintain the bridges since funding for their repair or replacement was in question.
Who pays to fix mailboxes damaged by plowed snow depends on where the mail customer lives and who plows the road.
The state and some townships will not compensate mailbox owners if plowed snow damages their rural delivery boxes. Other townships will either compensate the owner or fix the boxes.
Getting around bridges with new, lower weight limits will be inconvenient and expensive, local trucking firm officials say.
The new limits PennDOT plans to list for ten Southern End bridges will send trucks on lengthy and expensive detours, truckers said.
The new weight limits could also delay responding emergency equipment.
