The Darien Department of Public Works has announced the Connecticut Department of Transportation will close Camp Avenue to all traffic at the railroad crossing between Greenwood Avenue and Hoyt Street for about a week starting next Friday.

The closing of the crossing to traffic is being done so Metro-North Railroad can repair or replace sections of track near crossings, and to enable a continuing project to rebuild the railroad bridge over the Merritt Parkway on the 7.9-mile New Canaan branch.

The project will include restoring track and crossing surfaces at two railroad crossings in New Canaan and two in the Springdale section of Stamford as well as measures to improve drainage, according to Darren Oustafine, assistant director of public works for Darien.

The ongoing work— including the bridge replacement project over the Merritt Parkway — has required busing from Friday nights starting with the 10:58 a.m. train from Stamford to New Canaan through Sunday since July 31, with the substitution to continue through the weekend of Aug. 22 and 23. The weekend buses run 20 minutes earlier than normally scheduled trains to accommodate additional trip time, according to Metro-North Railroad.
