One-way traffic in place at Ponus Ridge overpass

A temporary one-way signal was installed at the Ponus Ridge Road in New Canaan overpass to the Merritt Parkway last week as part of the Merritt Parkway Improvements project.
The alternating one-way traffic became full operational on Monday, July 28, and will continue 24 hours a day until the end of the summer, according to the state Department of Transportation.
The lane closure will allow the replacement of the roadway surface as well as the rehabilitation of the bridge deck, a DOT news release states. The rehabilitation includes concrete repair, new membrane waterproofing and a new pavement structure.
A temporary concrete barrier is providing an 11-foot lane "for the protection of the traveling public," according to the release.
"This will allow us to remove the existing wearing surface and examine the concrete bridge deck and make any necessary repairs," DOT spokesman Kevin Nursick said in an email. "Once complete we will `flop' traffic and complete the repair work."
The $57 million parkway improvements project, which slated to be completed Sept. 30, 2015, seeks to rehabilitate more than 12 miles of northbound and southbound lanes as well as 12 several bridge structures.
Work in New Canaan is also underway on the Old Stamford Road parkway overpass, where lane closures will continue during cleaning and patching operations, according to Nursick.
