As you get ready to hit the road for the holiday weekend, or if you are planning to travel anywhere on Connecticut’s busy interstate highways, take note of this… The exit signs on nearly a dozen major highways here in Connecticut are being renumbered. It comes as the state Department of Transportation replaces old signs to meet new Federal Highway Administration standards. The change will be gradual, but by the end of this decade, exit numbers will correspond with mile markers, and be based on how far they are from the beginning of the route within the state’s border… pretty much bringing Connecticut in line with the way exits are numbered now on most highways nationwide.
