Work is taking longer than expected to replace a heavily used but structurally deficient York County bridge that's been closed since May.

The contractor building a new bridge across Codorus Creek at the south end of Spring Grove needs another month to finish the job, PennDOT spokesman Mike Crochunis said Wednesday.

Most likely, Route 116 will reopen April 10 at the earliest, Crochunis said.

Motorists who use the road to travel between Hanover and York have been detoured around Spring Grove since May 22, when Allan A. Myers, LP of Montgomery County, started work to replace the 90-year-old bridge deemed structurally deficient.

PennDOT has estimated 17,000 vehicles use the bridge each day.

The new bridge will be 153 feet long and 40 feet wide, with an expanse that allows for two lanes and a sidewalk.

The $4.3 million project was supposed to be complete by the end of February.

But, Crochunis said, issues arose that caused delays - including Hurricane Sandy in October.

PennDOT and the contractor are negotiating a new deadline for a project originally bid to take 280 days, Crochunis said.

For now, PennDOT is not planning to impose financial penalties on the contractor for extending the deadline, he said.

"Their goal is to get it open as soon as possible," he said.
