The Connecticut Department of Transportation (CTDOT) is embarking on a significant infrastructure upgrade with a comprehensive sign support replacement project on Route 15 which began on September 9 and will continue until July 11, 2026. The project will span several towns including New Canaan, Greenwich, Stamford, Milford, Orange, Woodbridge, New Haven, Hamden, North Haven, Wallingford, and Meriden.
This extensive initiative, designated CTDOT Project No. 0083-0271, involves replacing outdated extruded aluminum signs and supports that no longer meet the current Manual on Uniform Traffic Control Devices (MUTCD) standards. The existing signage has shown signs of wear, inadequate retro-reflectivity, and structural deficiencies due to the increased size requirements for modern signage and current wind loading criteria.
The project also includes updating exit numbers from sequential to mileage-based numbering, in line with Federal regulations. Two new permanent variable message signs will be installed to integrate with the CTDOT’s Advanced Traffic Management System (ATMS) for Limited Access Highways.
Awarded to Ducci Electrical Contractors at a cost of $7.48 million, this project is being administered by the Bureau of Engineering and Construction, Office of Construction, District 3 in New Haven.
Motorists should anticipate various traffic adjustments during the project. Work on Route 15 will occur during the following times:
CT-15 Northbound in Greenwich Exit 28 Off-Ramp: 6AM– 6AM Monday–Tuesday; 6AM– 3AM Wednesday – Friday; 7AM – 3AM Saturday; 5AM – 6AM Sunday
