"With the opening of this entire eastern section, Forsyth County drivers finally have full interstate connectivity around the city's southeast side," NCDOT Division 9 Engineer John Rhyne said in the department's Sept. 18 release.
Kernersville is right at the east end of that new stretch. The sections between U.S. 421, I-40 and existing I-74 opened to traffic Sept. 19, two months ahead of schedule. With them open, the I-74 corridor now runs through eastern Forsyth County to where it meets U.S. 52 north of Winston-Salem. This is the first leaf season with that link open. For a Saturday trip to Pilot Mountain, Hanging Rock or Mount Airy, getting through Winston-Salem is no longer the hard part. What happens after you arrive is.
Three miles that change the trip
On paper the new piece is short. Segment AB runs from U.S. 421 to just south of I-40 and includes a multilevel interchange at I-40. Segment AA continues from there to the I-74 interchange. Together they cover about 3 miles and cost $387 million, built by prime contractors Webber LLC and Flatiron Dragados. Work started in 2022.
The project also changed roads you already use:
- I-40 was widened to three lanes in each direction for 2.8 miles.
- Kernersville Road now has a diverging diamond interchange. The Winston-Salem Journal compared it to the existing diverging diamond on Union Cross Road at I-40, so if you drive Union Cross, the layout will feel familiar.
- N.C. 192, the old I-74 connector to I-40, was widened and resurfaced for 2 miles.
For the exit numbers, a highway photo log shot on opening day shows the eastbound I-40 ramp to the new I-74 Beltway signed as Exit 198 and the Kernersville Road interchange as Exit 55. FOX8 lists the full corridor's connections: I-40, U.S. 421, U.S. 158, U.S. 311 and U.S. 52.
Nobody has published measured time savings yet. At the Aug. 28 ribbon cutting, NCDOT officials told ABC45 that the full I-74 loop could save drivers 10 to 15 minutes on their commutes. That was a forecast made before opening. The same report puts traffic through the area at more than 100,000 vehicles and trucks a day. We found no post-opening traffic reports for I-40 through Kernersville, Union Cross Road or Salem Parkway, so for now the savings are an estimate.
Pilot Mountain's summit gate is the new slow spot
A smoother drive north doesn't add parking at the top. Pilot Mountain's rule is simple. When the summit parking lot fills, the park closes the summit-road gate. It reopens the gate when spaces free up. Cars can't line up on the road or in front of the visitor center to wait. On its park page, NC State Parks warns of weekend and holiday delays. A current alert on the park's news page says summit-road access depends on parking availability and road conditions.
That gate matters more than which exit you take. The summit lot is where the Pilot Knob Trail starts, the loop around the base of Big Pinnacle, where climbing is not allowed. A faster drive only helps if the lot still has room when you arrive. If you're aiming for the summit, plan around the lot, not the highway.
If the gate is closed, the trails lower on the mountain are still an option. The park lists its hiking and bridle trails as open, and its trail list includes the Mountain Trail and the Corridor Trail. NC State Parks lists no timed entry or shuttle at Pilot Mountain. The capacity gate is the only access control.
Hanging Rock is a day trip only this year
Hanging Rock's trails are open, too. Hiking, bridle and bike trails are all listed as open, but the swim lake and boat rentals are closed. The swim beach and lake season ended Sept. 7, 2026.
The bigger change for this fall is overnight stays. The campground is closed for bathhouse and campsite improvements and is expected to reopen before fall 2027. The vacation cabins can still be reserved. So for 2026, a Hanging Rock trip from Kernersville is a hike-and-home day trip unless you book a cabin. A quicker drive makes that easier to fit into a Saturday.
The forecast pushes the trip later
Timing is the next question, and this year's forecast doesn't give an easy answer. NC State's College of Natural Resources 2026 forecast, published Aug. 26, says the Piedmont may have some of the least favorable conditions in the state. Above-normal temperatures could delay the color change, and ongoing drought could cause early leaf drop or muted color. In its general timeline, peak color reaches the foothills and Piedmont in late October to early November. Elevations between 4,000 and 5,000 feet peak in mid-October.
So the color closest to Kernersville may arrive late, and it may not last long. That makes the late-October and early-November weekends the ones to watch, and Mount Airy has events on several of them.
Mount Airy's calendar matches the foothill peak
The 60th Autumn Leaves Festival runs Oct. 9 to 11 and ends tomorrow. Downtown Mount Airy's calendar keeps going after that, and the dates line up with NC State's foothill window:
| Date | Event | Where |
|---|---|---|
| Oct. 23–25 | Mayberry Ukefest | Historic Earle Theatre and Old-Time Music Heritage Hall |
| Oct. 31, 4–6 p.m. | Downtown trick-or-treating | Downtown Mount Airy |
| Fridays and Saturdays through November | Historic Downtown Mount Airy Ghost Tours | Downtown Mount Airy |
| Nov. 7 | Mayberry Half Marathon, 10K and 5K | Mount Airy |
| Nov. 7, 11 a.m.–4 p.m. | DÃa de los Muertos | Mount Airy Museum of Regional History |
Nov. 7 is the busiest day on that list, with the race in the morning and DÃa de los Muertos running through the afternoon. It also falls in the "early November" part of the forecast. On a day like that, Pilot Mountain's summit lot and downtown Mount Airy may both draw crowds. Starting the day at the mountain and ending downtown is one way to work around the summit gate.
Halloween is a two-town evening
On Oct. 31, Mount Airy's downtown trick-or-treating runs from 4 to 6 p.m. The Kernersville Chamber's free Downtown Trick or Treat runs from 6 to 8 p.m. that Saturday at and near the Chamber at 136 E. Mountain St. The two events run back to back, with Mount Airy's ending at the hour Kernersville's begins. Whether a family can do both depends on a drive time no one has measured on the new road yet. The schedules do allow a mountain afternoon followed by a Main Street evening at home.
Downtown Kernersville already has its own fall rhythm. The Downtown Kernersville Cruise-In listed Oct. 10 among its 2026 dates, and Körner's Folly held its Fall Vintage Market at 413 S. Main St. on Sept. 12. Our look at Kernersville's August festival Saturdays covers how the town's late-summer calendar is built. What's new this fall is a faster road north, which makes a foothills afternoon easier to pair with an evening downtown.
The rest of the loop is years away
The eastern loop is finished. Most of the western loop is not. NCDOT's project timeline lists Western Loop Section EA with right-of-way acquisition in 2028 and construction in 2030. Sections CA, CB and D are programmed for preliminary engineering only, and Sections A, BA and BB are not funded. Trips from Kernersville that head north and east of Winston-Salem now have a continuous interstate path. Trips to the west still go the old way.
The two-mile improvement of N.C. 192 and the wider I-40 are part of daily driving now, too, well after leaf season is over. More on how Kernersville connects to the rest of the Triad is on our Kernersville neighborhood page.
A new interchange can change how a commute adds up, and a commute is often what decides which part of the Triad a household picks. If the new loop has you rethinking how far you drive to work, or where your next move should be, The Jordan Factor can put together the timeline and the logistics. Let's Connect.
