Exit Number Changes On Merritt Parkway To Begin Soon: What To Know In Greenwich

GREENWICH, CT — Exit numbers along the Merritt Parkway will soon change.

Beginning on Monday, July 28, work will begin to update the exit numbers to a mile-based system from the New York state line to the Wilbur Cross Parkway.

For example, in Greenwich, Exit 27 near the NY border will become 19B; Round Hill Road Exit 28 will become Exit 3; Lake Avenue Exit 29 will become Exit 4; North Street Exit 31 will become Exit 5 - and so on.

Work is expected to take four to five weeks to complete. Temporary signs noting old and new exit numbers will be installed to help drivers adjust to the new system.

Drivers are being asked to plan ahead and drive carefully as crews complete the project.

According to the CT Department of Transportation, the mile-based system allows for uniformity with other states; helps drivers quickly determine distances to destinations; improves reporting of highway incidents, resulting in better navigation for emergency services; and makes it easier to add future exits without renumbering the entire corridor.

More information on the project, including an interactive map, can be found on the CT DOT website.
