Some eastbound lanes on portions of I-440 near the I-40/440 split will now be shut down at night.
It's part of 3-year rebuild project that will replace an 11-and-a-half mile stretch of freeway in southern Wake County. Daytime lane closures won't begin until mid December.
The DOT's Cris Mulder says 100,000 vehicles use this part of the highway every day and safety is the biggest concern.
"This is 30-year old concrete and pavement," Mulder says.
"This is about taking what's underneath, crumbling from the chemical reaction from what was used in the development and construction back in the day."
NC DOT will spend another $12 million to identify additional bus routes and park-and-ride options that could ease congestion. The project called "Fortify" should be completed by late 2016.
