U.S. Rout70 is a major east/west US highway providing a major link between the cities of Raleigh and Durham.

Route Description

US 70 enters Durham County from the southwest, then follows I-85 around the north side of the city of Durham. At exit 178, US 70 follows its own freeway through the east side of Durham, then transitions to a four-lane road with a continuous center turn lane along Miami Boulevard. In the midst of a commercial area at the intersection of Miami Boulevard/Mineral Springs Road, US 70 continues southeast on a median-divided roadway through a largely undeveloped area. US 70 then crosses over into Wake County, following Glenwood Avenue through Northwest Raleigh, after which it is joined by NC 50 at Creedmoor Road near Crabtree Valley Mall and later exits onto Wade Avenue, which has a trumpet interchange with US 401/Capital Boulevard. US 70 follows Capital Boulevard south into Downtown Raleigh. Capital Boulevard splits into Dawson (southbound) and McDowell (northbound) Streets, continuing south through Downtown, then follows South Saunders and later Wilmington Streets through South Raleigh. At the Garner town limits, US 401 forks onto Fayetteville Road and travels through the west side of town, while US 70/NC 50 fork to the east, establishing itself as the main business thoroughfare of the north side of town. NC 50 splits from US 70 at two-lane Benson Road, four-lane US 70 continuing southeast to I-40. US 70 and I-40 run concurrently between exits 306 and 309, where US 70 leaves Wake County along the Clayton Bypass freeway.


US 70 between I-540 in Raleigh and the East End Connector in Durham is planned to be converted into a six-lane freeway.  The project is designed to alleviate traffic congestion along the corridor and provide an alternate route to nearby I-40. Scheduled to begin construction in 2021, the freeway would be built in two phases.

Phase One focuses on the stretch between I-540 and the Wake/Durham County border. The project will build interchanges at Brier Creek Parkway and TW Alexander Drive. A third interchange at the location of the future Aviation Parkway extension would be used as a temporary connector between TW Alexander Drive and US 70.

Phase Two is the remaining section of the freeway, which will have an interchange with South Miami Boulevard/Mineral Springs Road. This phase of the project would require building adjacent service roads due to the higher concentration of driveways directly connecting to US 70 and heavy commercial development at the South Miami intersection.

Other projects include converting the Glenwood Avenue section of US 70 into a six-lane superstreet between I-540 and Duraleigh/Millbrook Roads in Raleigh. Construction on this section will begin in 2022. Additionally, NCDOT is developing plans to alleviate traffic congestion in the vicinity of Crabtree Valley Mall. One proposal involves modifying the interchange with I-440 to include a connection to Crabtree Valley Avenue.
