When the last section of the Outer Loop is finished, the toll road will be a bypass all the way around the southern edge of the greater Raleigh area - including linking I-40 west of Raleigh back to I-40 east of Garner.
But picking a final route has proven controversial, with Garner's leaders saying they don't want the highway coming through town on the so-called "Red Route."
In 2011, Garner got backing from the General Assembly when it passed legislation blocking that route. But then the federal Department of Transportation said it wouldn't make funding for the road available unless the Red Route was considered.
This summer, the General Assembly reversed course and repealed that law.
The NCDOT said Monday the "Complete 540" study for the southeast extension of the Triangle Expressway is once again underway following a two-year delay.
"Based on our 10-year Triangle Mobility Plan, we are focused on completing and rehabilitating roads including 540 that will continue to strengthen and connect our communities," said NCDOT Secretary Tony Tata.
