Ready or not, here they come.
The event takes place at the end of N.C. 540 (interchange with N.C. 55) just south of Research Triangle Park. TriEx will extend 540 south from N.C. 55 to the N.C. 55 bypass at Holly Springs. That part of toll road is to be open for business by January 2013.
The other part of TriEx, called Triangle Parkway, extending N.C. 147 south through RTP to NC 540, is to be open to traffic by January 2012.
To attend the groundbreaking, take NC 540 southwest from I-40, and drive until it ends. Don't take the final exit 66A for eastbound N.C. 55. Instead, look for attendants who will tell you where to park.
