3/31/2017 - Town of Darien Traffic and Detour Advisory


Advisory Issued:  March 31, 2017

Project Type:  Complete Replacement of the Old Kings Highway North Bridge over I-95

Area Affected:  Old Kings Highway North including the overpass over I-95

Duration of Project:  April 1, 2017-November 26, 2017


The Darien Legal Traffic Authority is advising motorists of a long term project to replace the existing bridge on Old Kings Highway North over I-95.  

The project will be commencing on April 1, 2017. 

By mid-April, local motorists may experience sporadic delays in the area as an alternating, one lane traffic pattern over the bridge may be in use during the daytime hours as the project gets underway.   

By the end of April 2017, a long term detour will be in place as follows:  All W/B Old Kings Highway North traffic (traffic coming up towards US-1) will be detoured onto I-95 northbound.  Motorists seeking to access US-1 (Boston Post Road) will quickly exit I-95 via exit 13 onto US-1.  This detour for W/B Old Kings Highway North traffic will be a 24-hour a day, 7-day a week detour for the majority of this project. Local motorists are advised to consider alternate routes.

E/B Old Kings Highway traffic (traffic coming from US-1) will be allowed to travel through the area and access I-95 northbound and all points east on Old Kings Highway North for the duration of the project, except on those overnights where a complete closure of Old Kings Highway North is required (as detailed below). 

The Connecticut DOT requires up to eight (8) overnights where the Old Kings Highway North bridge and the surrounding area will be completely closed to all traffic.  This is required to set portions of the steel superstructure of the bridge into place. Appropriate detour signage for all vehicles (cars and trucks) will be prominently posted to assist motorists in the area.  The eight overnights will not be consecutive and further traffic updates will be issued by the Darien Police Department as the specific dates are identified.      

Further questions on the local impact of this project can be directed to Captain Don Anderson of the Darien Police Department by phone at (203) 662-5312 or via email at
