Major Highway Systems of Raleigh
- I-40 traverses the southern part of the city, connecting Raleigh to Durham and Chapel Hill toward the west, and coastal Wilmington, North Carolina to the southeast.
- I-440, Also known locally as the Raleigh Beltline, it makes a loop around the central part of the city. The I-440 route labeling formerly encompassed the entire loop around the city, co-numbered though South Raleigh with I-40. In 2002, the NCDOT removed the I-440 designation from the co-numbered I-40 (southern and southwestern) sections of the loop, and the directional signage on the remaining I-440 portion was changed from Inner/Outer to East/West. The route designation changes were made to avoid driver confusion over the Inner/Outer designations, especially with Raleigh’s new “Outer Beltline”, as I-540 has become known.
- I-540/NC 540 is currently under development. It is a partially completed outer beltway that will run around the outer edges of Wake County and into a small portion of southeast Durham county. The route is complete and currently open between the NC 55 Bypass interchange Holly Springs and the US-64/US-264 interchange in suburban Knightdale. The route is tolled between NC 54 in Cary to its current southwestern terminus at NC 55 Bypass. Completion of the loop is planned (but unfunded), and also contingent upon selection of an agreeable route around the town of Garner.
- I-87, designated September 5, 2017, follows the former route of Interstate 495. It begins at the I-40/I-440 interchange southeast of Raleigh and runs east, meeting I-540 and terminating at Rolesville Road. It is entirely concurrent with US 64. When the route is completed it will link Raleigh to the Norfolk, Virginia area.
- Interstate 42 will begin at I-40 south of Raleigh and will follow US 70 to Morehead City.
United States Highways
- S. Route 1 enters the city from the north along Capital Boulevard, joins I-440 around the west side of Raleigh, and leaves the city to the southwest as the US 1/US 64 expressway in Cary.
- S. Route 64 is the main east-west route through Raleigh; all segments share routes with another highway. East of the city, US-64/US-264 is known as the Knightdale Bypass. US 64 follows I-440 (as a wrong way concurrency) and I-40 along southern Raleigh, and US 1 to the southwest. A former alignment, designated as Business US-64, follows New Bern Avenue from the I-440 Beltline to the eastern boundary of the city, where it continues into Knightdale.
- S. Route 70 runs roughly northwest-southeast through Raleigh. North of downtown, the route follows Glenwood Avenue into Durham. South of Raleigh, the route (along with US 401 and NC 50) follows South Saunders and South Wilmington Streets into Garner. Through downtown, US 70 uses small segments of several streets, including Wade Avenue, Capital Boulevard, Dawson, and McDowell Streets.
- S. Route 264 cosigned with US 64 through East Raleigh.
- S. Route 401 north of downtown Raleigh it follows Capital Boulevard and Louisburg Road. South of downtown it is cosigned with US 70 from Wade Avenue southward.
