Capital Boulevard is a major thoroughfare connecting downtown Raleigh to its northeast suburbs.
Capital Boulevard begins at the north side of Downtown Raleigh, southbound traffic emptying onto Dawson Street and northbound traffic being siphoned from McDowell Street. Capital Boulevard is designed as a four-lane expressway, with limited driveways and grade sparations at several locations as it travels through an industrial area. At the I-440 interchange, Capital Boulevard transitions into to an eight-lane urban boulevard, featuring numerous signalized at-grade intersections through a largely commercial area, driveways becoming more frequent. The commercialized development ends at Triangle Town Center, near the I-540 interchange. North of I-540, Capital Boulevard continues as a four-lane arterial road, crossing into the town of Wake Forest after crossing the Neuse River. Commercial development occasionally appears as the roadway bypasses Raleigh's large Wakefield Plantation development to the east and Wake Forest to the west. The Capital Boulevard designation ends at the Wake/Franklin County border, US 1 continuing north to I-85 in Henderson.
