The second phase of the Rhode Island Department of Transportation’s program to renumber exits on interstates and some state highways will soon be underway.
"In mid-December, RIDOT will be changing exit numbers on two highway segments and providing exit numbers for two others that do not have them," according to a press release.
RIDOT said drivers will soon see new exit numbers on Route 4 in Warwick, East Greenwich and North Kingstown, and on Route 78 in Westerly. Route 403 in East Greenwich and North Kingstown and the Airport Connector in Warwick will get exit numbers for the first time.
"This project also will upgrade faded and deteriorated guide signage along these routes, as needed," RIDOT said.
The project will eventually see new exit numbers assigned on Interstate 95 and Interstate 195, as well as Routes 10, 24 and 37.
RIDOT began the effort last year with the renumbering of exits on I-295 from Warwick to Cumberland.
The department said the new exit numbers are keyed to mile markers, which is a system that's been used throughout the country for years.
"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's Manual on Uniform Traffic Control Devices for Streets and Highways," RIDOT noted. "The highway exit numbers traditionally were assigned sequentially."
The old exit numbers will be temporarily displayed along with the new numbers to help drivers get used to the change.
The Department of Transportation listed the old and new exit numbers on its website.
