The freeway plans are from I-540 in Raleigh to Lynn Road in Durham. The N.C. Department of Transportation said the changes will improve congestion, travel time and safety.
According to the NCDOT, the area sees poor traffic flow and a high number of crashes, and conditions are expected to get worse if no action is taken.
There are two parts to the proposal -- the first in Raleigh would turn the intersections of Brier Creek Parkway and T.W. Alexander Drive into interchanges.
The second extends the freeway into Lynn Road in Durham.
The plan would get rid of driveways and direct access from homes and businesses along that part of 70. Instead, motorists would see interchanges with ramps and bridges. If approved, the estimated $90 million project would start in 2021.
The public is invited to share their input Tuesday at the Embassy Suites on Arco Corporate Drive in Raleigh between 4 and 7 p.m. Another meeting will be held in Durham on Thursday.
