I-40/NC 42 Interchange Improvements (Exit 312)

NCDOT TIP # I-4739
Project Type:
 Interchange improvements
Affected Counties:
Estimated Cost: $


The North Carolina Department of Transportation (NCDOT) plans to improve the interchange at I-40 and NC 42 (Exit 312) in Johnston County. Improvements include a new traffic pattern, new ramps, and a new type of interchange design for the Triangle area.

The NCDOT proposes what is known as a diverging diamond interchange design. This means drivers on NC 42 must switch sides of the road temporarily, but can then make a left turn onto the I-40 interstate. While this may sound confusing, the NCDOT claims it will help keep traffic moving across the bridge by reducing the amount of time drivers have to wait at stop lights.

The purpose of these improvements is to alleviate congestion at the interchange. It is a part of one of the NCDOT’s three major projects to update the roadways in the Triangle.

There are only a handful of attorneys in NC who practice eminent domain exclusively, and even fewer with NCDOT experience. We have several. That’s why its worth getting in touch with us for a free case evaluation.

Here’s how it works:

1) Tell us about your situation.

2) We research your property as needed, using DOT maps, our own technology, and experience to see the exact effects.

3) We let you know what we think a fair offer would be. This evaluation is free, and there’s no
pressure or obligation to hire us after.

But please don’t wait to act. Waiting can hurt your case, and the cost is the same: free.
