Bridge replacement will delay I-84 traffic
Motorists traveling on I-84 over the next several weekends may run into some traffic delays due to planned construction in the Danbury-Southeast area.
The New York State Department of Transportation is replacing two bridges over Dingle Ridge Road in the Putnam County town of Southeast. As a result, the bridges will be closed to traffic on specific days.
The first closure will take place Sept. 21-22. Westbound traffic will be diverted at Exit 1 in Danbury onto Route 6 and allowed back on to I-84 at Exit 20 in Southeast. The closure will begin at 5 p.m. on Saturday and is expected to last through part of Sunday.
Eastbound traffic will be diverted one of the following weekends: Sept. 28-29 or Oct. 5-6. At that time, the eastbound section of the road will be closed at Exit 20 in New York at 5 p.m. on Saturday and directed back onto I-84 at Exit 1 in Danbury.
Traffic delays are anticipated and motorists are encouraged to use alternate routes.
The project will use a technique called accelerated bridge construction, in which a new bridge will be constructed adjacent to the existing bridge on a rail system. On the weekend of each closure, the existing bridge will be demolished and the new bridge slid into place. When the road is closed, the approached will be raised approximately two feet to meet the new bridge elevation and then the bridge will be reopened.
With this technique, each bridge closure is expected to last less than 24 hours.
