Delivering and hauling in Sanford, NC: US 1, US 421 and the new plants

The short version

Sanford is the seat of Lee County, about 40 miles southwest of Raleigh. Most trucks reach it on the US 1 freeway or the US 421 bypass. [11][25]

It's a manufacturing town. Caterpillar is one of the county's three largest employers, and the state's 2025 profile lists it with more than 1,000 workers. [34][11]

Two big projects were announced in 2026: a STERIS campus with its own rail spur, and a new Caterpillar plant worth about $1 billion. Expect construction loads first and new freight later. [7][10][11]

NCDOT has three road jobs running or due in the county: two resurfacing contracts on US 1, US 421 and US 15-501, and the NC 42 widening toward Broadway. [1][2][3]

Everything here is as of October 2026. Plans and lane closures change, so call the receiver and check DriveNC before you roll. [1][2]

Getting in: US 1, US 421 and the bypass

US 1 is a freeway through Chatham and Lee counties. It links Sanford to Apex and Raleigh to the north and to Southern Pines to the south. [25]

Coming south from Raleigh, the Moncure exit is 79. Exit 71 is US 15-501 and NC 87. Exit 70 is the cloverleaf with the US 421 bypass. [25]

Below that, Exit 69 serves US 421 Business on North Horner Boulevard and Burns Drive. Exit 68 is Spring Lane and Exit 66 is NC 42 at Wicker Street. [25]

These numbers come from a roads enthusiast guide last updated in 2020, not an NCDOT page. Our tip: get the receiver's exit in writing. [25]

US 421 skirts Sanford on a freeway bypass of about 12 miles. It heads northwest toward Siler City and Greensboro and southeast toward Lillington and I-95. [25]

US 421 Business is the old route through town along Horner Boulevard. It's about 10 miles long and runs past downtown, so expect signals and local traffic. [26][25]

Road work as of October 2026

In November 2025, NCDOT gave S.T. Wooten a $3.6 million contract to repave two highways. The work has until summer 2027 to finish. [1]

One piece is about 3.6 miles of US 421, from the Chatham County line to north of the US 1/15-501 interchange. It includes the ramps at the US 421 and Business 421 interchange north of Sanford. [1]

The other is about 4 miles of US 1, from the Moore County line to Wildlife Road. The job adds rumble strips and new high-visibility lane markings. [1]

In February 2026, NCDOT gave Highland Paving a $3 million contract for about 20 miles of paving, due by fall 2027. [2]

That one covers US 15-501 from the Moore County line to the US 1/15-501 junction, US 1 near Tramway, and 14 secondary roads, including Buckhorn and Blacks Chapel roads. [2]

We found no 2026 update on whether either crew has started. Look for nighttime lane closures on DriveNC before a Sanford run. [1][2]

NCDOT is also widening NC 42, known locally as Broadway Road, between Sanford and Broadway. Work began in fall 2023 and is due in spring 2028. [3]

That job has brought weekend closures for pipe work. In November 2025, the detour used NC 42 (Avents Ferry Road), Longstreet Road and Woodland Trails Road. [3]

Who ships and receives here

Caterpillar has built compact equipment in Sanford since 1999. In May 2026, ABC11 reported it planned to hire 600 production workers there. [12][14]

On Sept. 30, 2026, Caterpillar announced about $1 billion for a new Sanford plant to build more compact track loaders and telehandlers. [11][12]

Spectrum News reported local incentives of about $40 million from the city and $46 million from Lee County. Caterpillar didn't give a job count or an opening date. [11]

Caterpillar also has North Carolina plants in Clayton, Goldsboro and Winston-Salem, the same report noted, so some loads may run between them. [11]

STERIS chose Helix Innovation Park in Sanford for a $600 million campus with 335 jobs, the state announced on Aug. 5, 2026. [7]

The 600,000-square-foot site will hold manufacturing, labs, a warehouse and distribution. The state's release gave no opening date. [7]

Kyowa Kirin announced a biologics plant of up to $530 million on a 75-acre Sanford campus in June 2024. It aimed to be fully running by 2027. [17]

The plan called for a 171,700-square-foot building with two production reactors and more than 100 jobs, backed by $10 million in performance-based incentives. [17]

We found no 2026 update on Kyowa Kirin. If you're quoting a load there, confirm the receiving address and dock hours first. [17]

Besides Caterpillar, the state's 2025 profile names Wyeth Holdings and Lee County Schools as the county's other employers with more than 1,000 workers. [34]

Rail at Helix Innovation Park

The North Carolina Railroad Company is putting up to $600,000 into design and construction of rail on the STERIS campus. [10]

STERIS plans to receive and ship at least 160 rail cars a year by 2031, the railroad says. That's on top of truck freight, not instead of it. [10]

The state's release lists Norfolk Southern, NCDOT's Rail Division and the NC Railroad Company among the project's partners. [7]

Our tip: once the spur opens, expect some drayage between the rail siding and other Sanford plants. Ask the shipper who handles transloads. [10]

Truck limits and local rules

NCDOT's statewide truck restriction table, last updated March 5, 2024, has no rows for Lee County. [23]

Nearby, Moore County bans through trucks with three or more axles on NC 5 between Aberdeen and Pinehurst. [23]

In Harnett County, SR 1703 bans trucks over 26,000 pounds between US 421/NC 55 and Denim Drive, per the same table. [23]

NCDOT's posted-bridges table for primary routes, dated Oct. 9, 2026, lists no bridges in Lee County. It doesn't cover secondary roads, so check NCDOT's posted-bridge maps for back-road deliveries. [22]

NCDOT's ordinance manual says towns have no statutory authority to ban trucks from state highway routes. City streets are a different matter. [24]

We couldn't read Sanford's city code, so we can't tell you its truck routes, parking rules or loading zone hours. Watch the posted signs and ask the receiver. [24]

Downtown in December

Sanford's 2026 Christmas parade will use a new route, The Rant reported Sept. 2. City Council approved the street closures on Sept. 1. [27]

Downtown Sanford Inc. asked for the change. If you deliver to a downtown shop in December, ask the receiver about the parade night. [27]

The route starts at Steele and Carthage streets, then runs along Carthage, Vance, Wicker, Moore and back on Carthage near Depot Park. [27]

The change makes room for NCDOT work planned on the west end of downtown. The date and closure times weren't in the report, so check before a December delivery downtown. [27]

That NCDOT work is the Carthage Street project, U-5709. Its 2018 plan calls for a raised median and roundabouts at Fire Tower Road, Fields Drive and Wicker Street. [31]

NCDOT's tentative letting list puts it in September 2027 at an estimated $22.2 million. That means construction isn't under way yet. [30]

Rest, parking and a call-ahead checklist

NCDOT lists no rest area on US 1 in North Carolina. The nearest public ones are on I-95 and I-40, outside Lee County, so plan your break before you exit. [38]

We didn't find an official list of truck stops or truck parking in Lee County. Don't plan to stage on a city street without checking the signs. [38][24]

Hauling past Moncure? The VinFast site there is tied up in a state lawsuit filed in May 2026, so it isn't a freight stop. Our Toyota battery plant guide has more. [32]

Before a Sanford run, check DriveNC for US 1, US 421 and US 15-501 paving, and for Broadway Road closures on NC 42. [1][2][3]

Ask the receiver which exit to use, whether the dock is inside a new construction site, and where you can wait if you're early. [7][11]
