The Triangle Expressway is an 18.8-mile toll road that extends the partially complete "outer loop" around the greater Raleigh area from I-40 to the N.C. 55 Bypass. The six-lane highway relieves congestion on N.C. 55 and reduces travel times for commuters traveling to the Research Triangle Park.
The Triangle Expressway currently has two sections: Toll N.C. 147 and Toll N.C. 540.
- Toll N.C. 147 is 3.4 miles long between I-40 and Toll N.C. 540.
- Toll N.C. 540 is 15.4 miles long between N.C. 54 in western Cary and the N.C. 55 Bypass near Holly Springs.
Rates displayed are for two-axle vehicles.
Note: Rates for vehicles with three axles are two times (2x) the 2-AXLE vehicle toll. Rates for vehicles with four or more axles are four times (4x) the 2-AXLE vehicle toll.
