Hilton Head council presses partners for March 31 decision on US‑278 bridge, funding and corridor scope

Hilton Head Island town council members spent the Jan. 27 workshop urging staff and county partners to clarify costs and roles ahead of a Jan. 30 meeting with the South Carolina Department of Transportation and Beaufort County and a March 31 deadline for a clear funding direction.

Council and staff focused on four interrelated questions: whether the town and county want to fund a reduced, roughly $300 million project scope; whether the eastbound bridge should be built as a two‑lane or three‑lane structure with breakdown shoulders; whether the bridge should include a separated 10‑ to 12‑foot bike/ped pathway; and which local and state sources (including the State Infrastructure Bank, or SIB, and the 2018 transportation sales/use tax referendum) can be applied to which segments from Moss Creek Drive through Spanish Wells and the Cross Island Parkway.

The meeting was a planning session rather than a vote. Town staff said they will attend the Columbia meeting with Beaufort County and DOT, collect DOT’s segment cost breakdown, and provide a written summary to council after the Jan. 30 session. Jared, a Beaufort County representative at the workshop, told council that DOT’s three‑lane concept under discussion calls for three 12‑foot lanes plus a 6‑foot inside shoulder and a 10‑foot outside shoulder; DOT and federal funding requirements could limit which elements can be changed without generating new environmental review.

Why it matters: DOT has told the town and county it needs clear direction by March 31 so it can proceed with a bridge replacement on a schedule that could begin construction in 2027. Council members said a short timeline requires them to pick a funding approach and a prioritized list of corridor elements so county, state and federal partners can determine what will be built with available funds.

Key points from the workshop

• Funding and scope. Staff and council reviewed a staff report that lists roughly $298–300 million in combined funds composed of DOT funds, SIB support and local referendum and county sales‑tax proceeds. Council members repeatedly asked DOT and the county for a detailed cost breakdown (bridge, causeways, Moss Creek and Stony corridor segments) because SCDOT’s most recent line items circulated to the town show an eastbound span estimate of about $258 million and an earlier corridor total near $488 million. Town staff said they have asked the county and DOT for a detailed engineers’ opinion of probable cost for each segment and element so the council can decide which elements must fit inside the local $300 million envelope and which would require new funding.

• Bridge design: two lanes vs. three. Several council members and members of the public debated whether to accept DOT’s three‑lane design (with breakdown shoulders) or insist on a two‑lane structure that preserves breakdown shoulders usable as an emergency / reversible lane. Jared told the council DOT’s position is that a three‑lane section would provide emergency capacity and future flexibility; DOT officials also warned that federal funding and environmental approvals constrain what can be altered without reopening certain reviews.

• Bike/ped pathway and Stony Corridor. Multiple council members and several public commenters — including local bike advocates and bicycling business owners — urged retaining a separated bike/ped pathway built to standards (commenters suggested 10–12 feet) because council members were told that adding such a pathway later would be difficult and costly. Council members also reiterated the need to protect the Stony community and to ensure corridor work does not create long‑term physical barriers; staff said a Stony Corridor master plan illustration will be developed to show how on‑island design choices align with the bridge scope.

• Windmill Harbor signal. Council asked for a cost and timeline to integrate the Windmill Harbor signal into the town’s adaptive, fiber‑based signal system. Staff estimated adaptive integration with mast arms, aesthetic fixtures and cameras would likely be on the order of $150,000–$200,000 for a full installation, while a minimal pole/camera solution would be lower; the county previously told staff the signal is unfunded if the town assumes operational control. Town staff said they will return cost and operational information and recommended holding off on major work until the broader corridor decisions are clearer to avoid duplicative spending.

• PSD water pipe and fixed costs. Council members raised a specific cost element: moving a raw water transmission line serving the island’s northern supplies is a fixed cost currently estimated at about $20 million with design in the seven‑figure range. The local public service district (PSD) expects reimbursement under the project; staff reminded council that reimbursement formulas applied historically (4% rule referenced in the discussion) may create a funding gap if the overall project scope shrinks and the fixed pipe relocation cost remains the same.

• Municipal consent and MOA. Several council members said the town’s municipal consent and the memorandum of agreement (MOA) with Beaufort County remain critical. Staff said the MOA and intergovernmental agreement with the SIB will need updates to reflect any revised scope. One council member said the town’s municipal consent provided earlier may no longer be valid given subsequent county responses; that view was presented as discussion, not as a formal council finding.

What staff will do next

Staff said they will attend the Jan. 30 meeting with DOT and Beaufort County, request an engineers’ opinion of probable cost broken down by the project segments listed in the staff report (bridge, causeways, Moss Creek, Windmill Harbor, Stony corridor and Cross Island Parkway connection), and provide a written memo to council summarizing outcomes. Staff also asked council members to submit, in writing, individual priorities for the project so the three council members attending the Jan. 30 meeting can represent the full council’s preferences.

Community reaction at the workshop

Thirteen members of the public addressed council during the public comment period. Several urged the council to accept the senator’s funding proposal and to approve a three‑lane eastbound design now; others — including multiple Stony community advocates and town council members — urged protection of neighborhood access, pedestrian safety and that any bypass/grade separation options be low impact. Bicycle and pedestrian advocates repeatedly urged that a separated pathway be included in the bridge design now because later retrofits would be costly or infeasible.

Background and next deadlines

Town staff reminded the council that DOT requested confirmation of funding direction by March 31. Beaufort County scheduled its workshop on Jan. 29; DOT and county staff explained the state meeting in Columbia is Jan. 30. DOT staff emphasized that if town and county cannot present a clear funding and scope direction by March 31, DOT may proceed with a bridge replacement limited to the elements it deems necessary to meet federal safety and schedule requirements. The council asked staff to return with a post‑meeting memo and schedule follow‑up sessions; staff said they will also develop an illustrative Stony Corridor master plan aligned to the bridge design options discussed.

Ending

Council members closed the workshop with staff direction to gather the DOT and county cost breakdowns and to prepare a memo and visual illustrations that will allow the council to weigh priorities before the March 31 deadline. The council did not take further formal action at the Jan. 27 workshop.
