What You Need to Know

What's Happening?

RIDOT in Fall 2017 began a highway renumbering program for its Interstate and other limited-access highways. These changes will be phased in over a four-year period.

As part of a separate project to replace outdated and worn out highway signage along Route 146, RIDOT is adding the mile-marker based exits. Previously, Route 146 did not have exit numbers.

The new exit numbers will be keyed to mile markers - a system used throughout the country for many years

Why is this Being Done?

Rhode Island and some of its neighboring New England states are among the last to change to this method of numbering its highways, as required by the Federal Highway Administration.

The highway numbers in Rhode Island were assigned sequentially.

What are the Benefits?

A mile-marker exit number system lets drivers know how far they need to travel to reach their desired off-ramp.

They also allow for easier expansion for future interchanges since the entire highway would not have to be renumbered to accommodate a new exit number.

Project Schedule

What's Next?

RIDOT is developing schedules for new segments of highways. The project also will include I-95 and I-195, as well as Routes 10, 24 and 37.
