PROJECT HISTORY

In May 2024 CTDOT advertised a sign replacement project along the CT 15/Wilbur Cross Parkway. The new signs would have milepost based exit numbers. As part of the project, exits would also be renumbered on the Merritt Parkway. Work started on renumbering the exits on the Merritt on July 28, 2025. By the end of the first week, numbers on the existing Cross Parkway exit signs began changing as well.

PROJECT SIGN PLANS

The plans for exit renumbering of the Merritt Parkway, only included the general set up for the new exit numbers and the old exit number signs.  For the Merritt, the old exit numbers will be listed on green signs matching the style of the exit signs, as shown in these plans for ground mounted and overhead signage:

For the Wilbur Cross, the Old Exit signs will be yellow, matching those put up on other routes in the state (signs are from I-384):

The plans also included a Feb. 23 revised list of new exit numbers. Checking this against the original list from last fall though, it doesn't appear any of the exit numbers were changed:

The project is to start on September 9, 2024. Work is to be completed by July 2026. It is not known whether the exit renumbering will wait until all the signs are replaced on the Wilbur Cross Parkway, or whether exits will be renumbered at least on the Merritt Parkway before  then. Here are examples of the sign plans for the Wilbur Cross Parkway segment of CT 15, heading north. New exit numbers run from 37 for the To I-95/US 1 Milford Parkway to Exit 62 for the CTDOT Maintenance facility in Meriden (apparently the signs at the end of the parkway for the I-91/CT 15 exits (64 A/B) are not being replaced, but receiving only new exit number overlays):
