Primary highways The Triad is home to an extensive
freeway network, which is in the process of undergoing a major expansion. Four major
Interstate highways and numerous secondary Interstate routes and
US routes serve the region: ;Interstate highways •
I-40, the primary east–west route across the region. In the eastern Triad, it is conjoined with I-85, which connects to The Triangle and points east. The two routes diverge near Greensboro. •
I-840 (Painter Boulevard), part of the Greensboro Urban Loop, currently under construction. When complete, I-840 will form the northern half of the loop. •
I-73, the primary north–south route across the region, much of which has yet to be constructed. The route mostly carries portions of
US 220 along it, with the exception of the portion along Bryan Boulevard, and another segment that shares the southwestern portion of the Greensboro Outer Loop. This portion was temporarily designated as
I-40, with the current and original
I-40 being re-designated as Interstate 40 Business. •
I-74, running across the region from southeast to northwest. Like I-73, much of the route has yet to be constructed, but several disjointed segments are currently open and signed as either I-74 or "FUTURE I-74". The route enters the region from the south conjoined with I-73, and diverges from there north of Asheboro toward High Point. The southern segment presently terminates at an intersection with I-40 east of Winston-Salem; new freeway is being built that will form the eastern segment of the
Winston-Salem Beltway. The northern segment leaves US 52 in Mount Airy, heading northwest out of the region. •
I-274, currently only in the planning stages, is the proposed designation for the western half of the Winston-Salem Beltway. •
I-85, connects the region to
Charlotte and points southwest. Enters from the east conjoined with I-40, and diverges from said route near Greensboro. •
I-285, connecting Winston-Salem to Lexington, is currently part of the
US 52 freeway being upgraded to Interstate standards. •
I-785, connecting Greensboro to
Danville, Virginia, the route is under development. It is currently part of
US 29, much of which is not Interstate standard. ;US highways •
US 29 runs roughly northeast to southwest across the region. Most of the route is either concurrent with, or parallel to Interstate highways, including I-785 (when completed) and I-85 (parallel). •
US 52 runs north–south through the region, serving as the main north–south freeway route through Winston-Salem. The entire freeway is planned for upgrade to Interstate standards. North of Winston-Salem most of the route is scheduled to become part of I-74 (until Exit 140 where existing I-74 starts and travels west along its own freeway, and US 52 continues north into town via expressway), while south of the city it is cosigned with I-285. •
US 64 is an east–west highway through the southern Triad, connecting Asheboro, Lexington, and Mocksville. •
US 70 is an east–west highway that closely parallels I-85 through the entire region. •
US 158 runs roughly northeast–southwest across the region, terminating in Mocksville at US 601 and US 64, just south of I-40. •
US 220 is currently the primary north–south route through Greensboro, and travels nearly symmetrically through the middle of the region; most of the route runs along I-73, except between Greensboro and Summerfield where it is named "Battleground Avenue" . •
US 311 is a nominally north–south route that runs northeast–southwest between Danville and Winston-Salem. The former alignment south of Winston-Salem has been fully signed as I-74; work has begun on US 311 signage removal on this alignment. •
US 421 enters the region from the southeast, and joins I-85 in Greensboro. It then takes I-85 south to I-73 north to western Greensboro. The route is then co-signed with I-40 briefly. After leaving Greensboro, it follows along
Salem Parkway, the rural area of Yadkinville, and continues into
Wilkesboro. ;
Air Piedmont Triad International Airport (GSO) Mass transportation Piedmont Authority for Regional Transportation (PART) is the Triad's 10-county regional organization with the goal of enhancing all forms of transportation through regional cooperation. PART Express Bus provides express service to each major Triad city from Piedmont Triad International Airport, while Connections Express connects the Triad to Duke and UNC Medical Centers. PART also has Express Bus service to outlying counties that surround the Triad including Surry, Stokes, Davidson, Yadkin, and Randolph Counties and soon to be Davie County. PART is also administering and developing several rail service studies that include both commuter and intercity rail. == Government ==
