Cary, NC — Three Triangle roads are getting faster with a planned increase from 65 to 70 miles per hour.
Triangle Roads Get Faster
The increase in speed from 65 to 70 mph, approved by the NC DOT, covers three roads:
- NC 147 south of I-40
Basically, all of 540 plus the new portion of 147 south of the interstate.
The change takes effect at the end of September.
I-540 and NC 540
It’s all the same road. But a bit of a legislative trick was required to toll the newest portion of 540 south of I-40 in Western Wake.
State law prohibits retroactively tolling an existing road, so the new extension had to technically be a new road.
For those who use 540 and the southern part of 147, the increase in speed will shave a few more minutes off the daily commute.
Here’s an unofficial map of the new high-speed routes.
