Hilton Head council weighs whether to narrow bridge ask or push for three lanes as SCDOT demands March 31 direction

Hilton Head Island’s town council spent its Jan. 27 workshop sorting through competing design and funding options for the US‑278 corridor and the island bridge, with the town, Beaufort County and SCDOT eyeing a March 31 deadline for a clear direction that could determine whether a federally funded bridge goes forward on a multi‑lane or a smaller scope.

Staff told the council the assembled local, state and SIB (State Infrastructure Bank) funds total roughly $300 million — including $80 million from the town’s 2018 transportation sales‑use referendum, about $21 million in county impact fees, a $120 million SIB allocation and roughly $72.5 million in SCDOT bridge funds — and that council must identify which elements it will insist be included in a final request to SCDOT and the SIB. Staff also said Beaufort County and SCDOT scheduled follow‑up meetings Jan. 29 (county) and Jan. 30 (SCDOT in Columbia) to clarify costs and scope.

Why this matters: SCDOT and federal funding rules constrain which parts of the project can be funded and when. Town staff and a county representative told council that adding elements that increase environmental impacts could trigger a new NEPA environmental review and change what federal funds can cover. A county official said the bridge funds are effectively federalized and that SCDOT needs a clear, narrow answer about the bridge by March 31 or the agency may proceed with its own project timeline aimed at beginning construction in 2027.

Council debate centered on two choices. A set of council members and many residents argued that the town should back Senator Tom Davis’s three‑lane replacement proposal — a larger capacity bridge that proponents say will address safety and long‑term capacity. "We cannot afford to have a one‑lane bridge to Hilton Head," said Andy Twistell, a resident who testified during public comment. "We need a bridge. We need it now." Other council members urged caution: they want to work within the approximately $300 million package, split the project into segments, get engineers’ opinions of probable cost by segment, and preserve key local priorities such as pedestrian and bicycle connections and community aesthetics.

"If we don't deal with the pathways now as part of this project, we've got decades before we can take it up again," a council member said during the meeting, urging inclusion of a bike‑ped pathway. Business and cycling advocates spoke at the public comment session as well: the owner of local bike shops and the head of a bicycle‑and‑walk nonprofit urged a separated 10‑ to 12‑foot path on the bridge, calling it an economic as well as safety investment.

Council members also pressed for a detailed, segment‑level cost breakdown. One council member highlighted a discrepancy between an earlier corridor estimate of about $488 million (which had included two‑way span replacements and corridor work through Spanish Wells) and a new figure provided by SCDOT of roughly $257.7 million for the eastbound span alone; staff said they had asked Beaufort County and SCDOT for an itemized probable‑cost report to reconcile the numbers ahead of the Columbia meeting.

On neighborhood impacts and design, councilors repeatedly cited the Stony community and historical guidance documents. Several warned against high, intrusive overpasses through Stony and asked that any design minimize displacements and protect neighborhood character; others proposed grade separations and frontage roads to eliminate signals and keep traffic flowing.

Funding constraints were a recurring theme. A Beaufort County representative cautioned that some funds are restricted — for example, certain county impact fees and SCDOT bridge funds must be used for safety and capacity; the town’s referendum dollars have been the most flexible local source. The county official also said having a federally funded bridge component increases environmental, design and impact considerations and that any project rebranding could require additional environmental review.

Public testimony at the workshop was extensive: residents, business owners and cycling advocates urged the council to provide a clear position at the upcoming meetings. Supporters of Senator Davis’s proposal warned that delaying or narrowing the town’s request could leave the island with a single‑lane or minimal replacement that would worsen traffic and safety risks. Others asked the council to insist on non‑vehicular access and neighborhood protections even while pursuing a bridge replacement.

Next steps: staff and the mayor said they will attend the SCDOT meeting in Columbia and Beaufort County’s Jan. 29 workshop, collect councilmembers’ written preferences for what should be included in the town’s project ask, and request a segment‑level engineer’s opinion of probable cost. The council also asked staff to produce a memo for members who could not attend. SCDOT has asked for a clear statement about whether the town and county will fund the additional gap so the DOT can plan construction; staff warned that municipal consent and an updated MOA with Beaufort County and the SIB intergovernmental agreement will need further work beyond March 31.

Procedural note: the council opened the workshop by adopting the agenda by voice vote, 7–0. The workshop concluded after public comment and a short discussion of next steps.
