After crossing Raleigh city limits, US 70, here called Glenwood Avenue, makes a connection with I-540 (exit 292), which goes to the front entrance of RDU Airport; the following Lumley Road/Westgate Road interchange (at exit 293) goes to the North Cargo and General Aviation area of RDU Airport. Adjacent to the airport is William B. Umstead State Park. With NC 50 joining US 70 at Creedmoor Road, US 70 crosses under I-440/US 1 after passing by Crabtree Valley Mall. Inside the Raleigh Beltline, US 70/NC 50 travel through a residential area until Wade Avenue, where they join US 401 along Capital Boulevard. In the downtown area, Capital Boulevard splits into Dawson and McDowell Streets; various sites are adjacent or nearby, including the North Carolina Museum of Natural Sciences and North Carolina Museum of History (via Jones Street), the North Carolina State Capitol (via Morgan Street), the Raleigh Convention Center, the Red Hat Amphitheater, and the Duke Energy Center for the Performing Arts (via South Street). Leaving the downtown area after the Martin Luther King Jr. Boulevard/Western Boulevard interchange, Dawson–McDowell Streets merge and become Saunders Street, which promptly exits the Raleigh Beltline crossing under I-40/US 64. In Garner, US 401 departs along Fayetteville Street towards Fuquay-Varina, followed by NC 50 along Benson Road towards Benson. East of Garner, US 70 merges with I-40 (exit 306A), while US 70 Bus. head towards Clayton. At the Wake/Johnston county line, US 70 splits from I-40 for the last time (at exit 309) and onto the Clayton Bypass.
