The completion of the bridge repair had been delayed due to the weather, officials said.
Quaker Road was closed down between Province Line Road and Mercer Road starting Aug. 20 so that workers could replace the bridge over Stony Brook. The bridge replacement project was originally expected to be completed within four to six months, but then Hurricane Sandy struck. Officials then announced the road would reopen at the end of March, but winter weather caused more delays.
The route is one of a few alternatives to Route 1 that drivers use to travel in and out of the Princeton area.
Kiser said the opening of the road Friday is weather dependent.
