On the night of Friday, Aug. 21, inside the Myrtle Beach Convention Center, a 40-year-old question appeared to get answered in under a minute. President Donald Trump, campaigning for appointed U.S. Sen. Darline Graham Nordone ahead of the Republican runoff, turned to the subject Horry County has argued about since the Clinton administration and told the crowd the money for Interstate 73 was already in place. “It’s all funded. It’s ready to go,” he said, addressing U.S. Rep. Russell Fry, one of the project’s most persistent advocates [Post and Courier, 2026].

Graham Nordone Wins: A Historic Moment for Horry County

Four days later, Graham Nordone defeated U.S. Rep. Ralph Norman 52.3% to 47.7% and became the Republican nominee for the November special election. 73% of Horry County voters chose Graham Nordone over Ralph Norman. In this pivotal moment Graham Nordone Wins because those in Horry County who did vote, voted overwhelmingly for her.

Those two facts sit next to each other in the timeline, and the sequence is the story. Not because a promise made during a campaign is automatically empty — presidents do move highway money — but because a promise made four days before a runoff, in the county whose turnout mattered most, deserves to be measured against the paperwork rather than the applause. As of this writing, no state or federal agency has produced that paperwork.

What was actually said, and to whom

Trump made the pledge twice: on stage at the rally, and in an interview with WMBF News. In the interview he named his transportation secretary directly, saying his people in Washington were fully behind the project and the necessary funding would be there [WMBF News, 2026]. On stage, he framed the interstate as a growth corridor for South Carolina and noted that Horry County intends to name it after him [WMBF News, 2026].

That last detail is not incidental. It is the mechanism by which this county has been trying to buy federal attention for two years.

The important thing to notice about the language is what it does not contain. There is no dollar figure, no funding program, no fiscal year, and no agency named as the source. “It’s all funded” is a statement about a condition that either exists in an obligation document or does not. Every other party with standing to confirm it has declined to.

What Columbia and Washington say

The South Carolina Department of Transportation, which would build the road, says it is waiting to begin until funding is identified — and it did not confirm that any new or additional money has arrived [WMBF News, 2026]. A day after the runoff, SCDOT was still saying the same thing: the source of the money has to be identified before work can start [WIS News, 2026].

Federal Highway Administration Administrator Sean McMaster told The Post and Courier in April that I-73 was not on the agency’s radar, while adding he would be glad to work with the state on it [Post and Courier, 2026]. That was four months before the rally. Nothing published since has shown that position changing through a grant award, an obligation, or a line in a bill.

There is also a structural question the rally did not address. A fully built I-73 is envisioned at roughly 80 miles and about $2 billion, running from Rockingham, N.C., through Marlboro and Dillon counties to the Grand Strand — what would be South Carolina’s sixth interstate [Post and Courier, 2026]. Grand Strand leaders have long focused on the shorter spur connecting the beach to I-95. It was not clear from Trump’s remarks which of the two he meant, and the difference is worth hundreds of millions of dollars.

The state’s own ledger tells a different story

The most telling evidence about I-73’s funding status is not federal. It is in Columbia.

Gov. Henry McMaster left I-73 out of his executive budget in 2024, 2025 and 2026. In earlier years he had asked lawmakers to set aside 0 million for it; 2024 was the first year he dropped it. He still supports expansion, but has said the project needs more local support first [WMBF News, 2026]. In 2021 he had gone further, standing with SCDOT and Horry County officials to propose a $300 million package drawn from federal pandemic relief dollars and a projected state surplus [Office of the Governor, 2021].

That $300 million ask has not been in a governor’s budget for three consecutive years. If a federal commitment of the size Trump described were real and imminent, the state’s own budget posture is the first place you would expect it to show up.

Meanwhile, SCDOT has kept the project technically alive. As of February, the department reported it had completed 99% of right-of-way acquisition between I-95 and Highway 501, 95% between Highway 501 and the Little Pee Dee River, with acquisition ongoing from the Little Pee Dee to Highway 22, plus construction plans, utility work and railroad coordination underway [WMBF News, 2026]. The corridor is largely bought. The permit was secured during Trump’s first term [WPDE, 2026]. What is missing is money, and only money.

What Horry County taxpayers have already put in

This is where the promise stops being abstract for people who live here.

In November 2024, county voters approved the RIDE IV sales tax program, which includes an estimated $450 million for the I-73 interstate connector running from Highway 22 to the Marion County line [WMBF News, 2026]. Under the county’s own terms, that local match covers up to half the construction cost of that segment and is tied to SCDOT actually having a construction contract in hand [Horry County Government, 2026]. The county had rejected an earlier 2021 funding plan precisely because it wanted to see federal and other municipal money first, while Myrtle Beach and North Myrtle Beach had already committed [WMBF News, 2026].

Read that structure carefully, because it cuts both ways. Horry County residents are paying a penny sales tax that includes $450 million earmarked for a road that cannot be built on local money alone — $450 million against a project estimated near $2 billion. The local share is real, collected, and conditional. If the federal commitment never materializes in an obligation document, that conditionality is what protects taxpayers. It is also what keeps the money sitting still.

Then came the naming campaign. State Rep. Heather Crawford filed H.4982 in January to designate the South Carolina stretch as the President Donald J. Trump Highway; the House passed it 76-28 on March 5 [WMBF News, 2026]. Horry County Council adopted a supporting resolution on Feb. 3 — and revised it in committee to add a clawback: the county’s support for the naming is withdrawn if funding is not allocated before Jan. 20, 2029 [ABC Columbia, 2026].

A county council that attaches an expiration date to its own flattery has told you exactly how much it trusts the promise.

Not everyone here wants the road

Accountability journalism requires reporting the opposition, and it is substantive. Conservation groups have warned that construction would cross the Little Pee Dee River and the Little Pee Dee Heritage Preserve, destroying wetlands and wildlife habitat, degrading river health, and worsening flooding for communities already vulnerable to property damage [Post and Courier, 2026]. The Horry County Democratic Party has objected that residents were never asked to vote on the naming [WPDE, 2026]. And among RIDE IV voters, a persistent argument has always been to fix existing roads first [WPDE, 2024].

The business case runs the other way. The Myrtle Beach Area Chamber of Commerce has argued for years that site-selection checklists screen out regions without interstate access, and its president welcomed the president’s apparent agreement on the project’s necessity [Post and Courier, 2026; WMBF News, 2026].

Three tests worth watching

Rather than relitigate the rally, watch for three concrete events. Any one of them would move this from rhetoric to record.

First, an obligation number. A federal commitment lives in a grant agreement, a discretionary award announcement, or a line in an appropriations or authorization bill. Congress faces a Sept. 30 deadline on surface transportation reauthorization, and Transportation Secretary Sean Duffy has already sent lawmakers a letter laying out the administration’s priorities for that bill [Bloomberg Government, 2026]. That legislation is the most plausible vehicle. If I-73 is genuinely “all funded,” it should be findable there.

Second, a construction contract. Horry County’s $450 million match is keyed to SCDOT having one. A letting notice is the moment the local money becomes spendable.

Third, the governor’s next executive budget. If McMaster restores a state match after three years of omission, that is Columbia signaling it believes the federal money is coming.

The bottom line

The rally produced a promise; the runoff produced a nominee. Neither produced a dollar that any agency has been willing to confirm. Horry County has done nearly everything a local government can do — permitted corridor, purchased right of way, a voter-approved local match, and a naming resolution offered as leverage with a deadline attached to it.

The remaining variable is federal, and it is verifiable. Residents should not have to take anyone’s word for it, in either direction. Between now and Sept. 30, the answer will either appear in a bill or it will not.
