The Connecticut Department of Transportation (CTDOT) is announcing that sign support replacements will be performed on Route 15 in Stamford, Greenwich, New Canaan, Milford, Orange, Woodbridge, New Haven, Hamden, North Haven, Wallingford, and Meriden. This project is scheduled to occur on Monday, September 9 and be completed on July 11, 2026. The project 0083-0271 consists of replacing existing extruded aluminum signs and sign supports that have exceeded their useful service life. The existing signs have less than adequate retro-reflectivity, have evidence of damage, or do not meet the current standards set by the Manual on Uniform Traffic Control Devices (MUTCD). The MUTCD standards require larger signs and therefore most of the existing sign supports are deemed structurally deficient based on the larger sign sizes and current wind loading criteria.
To be in conformance with Federal standards, exit numbers are also required to be revised from the existing sequential numbering to mileage-based numbering. Additionally, two new permanent variable message signs will be installed on CT-15 to align with the CTDOT’s statewide Advanced Traffic Management System (ATMS) for Limited Access Highways – Strategic Plan.
CTDOT Project No. 0083-0271 was awarded to Ducci Electrical Contractors at a cost of $7,482,000.00 on July 26, 2024, and is scheduled to be completed September 11, 2026. This project is administered by the Bureau of Engineering and Construction, Office of Construction, District 3 in New Haven.
