Triangle Expressway

The Triangle Expressway (TriEx) is the first modern toll road built in North Carolina, and one of the first toll roads in the United States built to use only electronic toll collection instead of toll booths. The overall freeway consists of three segments called the Triangle Parkway, the Western Wake Expressway, and the Southern Wake Expressway, totalling up to 32.4 miles (52.1 km) long. The six-lane Triangle Parkway extends Interstate 885 (I-885) 3.5 miles (5.6 km) via North Carolina Highway 885 (NC 885) in Durham County to meet North Carolina Highway 540 (NC 540) in Morrisville in Wake County. The Western Wake Expressway extends 12.4 miles (20.0 km) long, extending NC 540 to meet NC 55 in Apex. The Southern Wake Expressway extends 16.5 miles (26.6 km) long, extending NC 540 to meet I-40 and I-42 southeast of Garner.

The money for the project comes from $625 million in bonds and a $387 million loan from the federal government. The North Carolina Turnpike Authority deposited this money on July 29, 2009, and on the same day the agency's executive director David W. Joyner signed contracts to pay $584 million of that money to three companies to build the road over the next 42 months, creating 13,800 jobs.[citation needed]

S. T. Wooten Corp. of Wilson, North Carolina built the 3.4-mile (5.5 km) northern section, an extension of NC 147, called the Triangle Parkway, at a cost of $137.5 million, including an electronic toll plaza on I-540. The new road opened for traffic on December 8, 2011 and extends from the previously existing section of NC 147 (now I-885) south from I-40 to an 2.8-mile (4.5 km) section of the Northern Wake Expressway. Completed in 2007, the existing section became part of the toll road on August 2, 2012. Originally envisioned as part of I-540, because of rules against tolls on Interstate Highways, this section is now called NC 540. When Research Triangle Park (RTP) was created in the late 1950s, a corridor of land was preserved to be available for the Triangle Parkway's eventual construction. Another $230 million was spent on 525 acres (2.12 km2) of additional right-of-way for the entire road.

Actual tolling of the new section of road began January 3, 2012.

Granite Construction of Watsonville, California, and Archer Western Contractors of Atlanta worked together as Raleigh Durham Roadbuilders to complete the 12.6-mile (20.3 km) Western Wake Freeway at a cost of $446.5 million. This section of the Triangle Expressway, which extends from NC 55 at RTP to NC 55 at Holly Springs, will become part of NC 540. In summer 2009, work began on the freeway. On August 1, 2012, the 6.6-mile (10.6 km) second section from NC 55 to US 64 opened, with the remaining six miles south of US 64 to NC 55 in Holly Springs opening December 20, 2012. Tolls and $25 million a year from the North Carolina legislature will finance the project.

The Triangle Expressway is built as an all-electronic toll road with billing by license plate, similar to Maryland's Route 200 (InterCounty Connector, largely opened to traffic in 2011).

Drivers can open an account and use a North Carolina Quick Pass transponder, which results in a lower rate. Other drivers will have their license plates photographed, and they will receive a bill. The expected rates are 15 cents per mile (9.3 ¢/km) for those with transponders, and 24 cents per mile (15 ¢/km) for others.

On May 4, 2010, the Turnpike Authority signed a contract with TransCore to provide transponders. Drivers can, however, use their existing accounts; North Carolina becomes the only state to offer this option. 350,000 new transponders are expected to be issued in the first five years. Transponder sales began October 11, 2011. In later years, interoperability was established with the following ETC systems: E-ZPass, Peach Pass and SunPass.
