Johns Island's Commute Is Being Rebuilt in Pieces. Which Pieces Are Already Paid For?

When you tour a house on Johns Island, which road does your weekday drive actually use? For years the answer barely mattered, because every route off the island had a project promised for it. That changed this year. The island's road work now falls into several different funding categories, and the category your route falls in tells you more about your commute than any listing description.

This post reaches you a few days before Charleston County voters decide on a half-cent transportation sales tax on November 3. The plan would raise about $4.25 billion over 25 years. For a Johns Island buyer, that vote matters for one side of the island much more than the other.

Two ways off the island, two kinds of money

Most daily trips off Johns Island use one of two corridors. Main Road leads toward US 17 and the Limehouse Bridge. Maybank Highway crosses the Stono River toward James Island and the peninsula. The table below sorts the major projects on both corridors by where their money stands today.

On the Main Road route toward US 17, the work is either built or under contract, while the Bohicket stretch has nothing scheduled. On the Maybank side, half the job is finished, one lane is in design, and the largest remaining piece depends on the referendum.

The Main Road side runs on a signed contract

Charleston County scheduled the new roundabout at Main, River, and Chisolm roads to open at 6 a.m. on Monday, October 19. River Road closed over the weekend before that while crews finished stormwater pipe and paving. Charleston County's release described the opening as a major milestone in the US 17 and Main Road Improvements Project, and Council Chairman Joe Boykin said, "There's more work ahead."

The work ahead is Segment A, which is the bigger commitment. According to the August 2026 project newsletter, Segment A is funded by the 2016 Transportation Sales Tax and includes new flyover off-ramps from US 17 to Main Road, a spur bridge over US 17, roadway widening, and expanded bike and pedestrian connections. The design-build contract with the Archer-United-Banks Joint Venture is worth $354,312,450 and runs 1,458 days, with an anticipated completion date of September 27, 2028. As of August, pile driving for the ramps was about 95% complete. The Ramp 3 connection to northbound US 17 was expected in the fourth quarter of 2026, and construction of the Main Road spur bridge was set to begin soon.

That certainty does not cover the whole corridor. Segment C would have improved Bohicket Road from Maybank Highway toward Betsy Kerrison Parkway, with widening, intersection changes, and a multi-use path. It was estimated at $75 million to $90 million, out of $195 million budgeted for all three Main Road segments, according to the Post and Courier. In 2024, only 23% of 430 public comments supported the County's preferred plan, according to the Post and Courier. The County stopped work after a February 6, 2025 Finance Committee update. Boykin later told the Post and Courier that the project proved so unpopular the County abandoned it and shifted the money to other projects.

If your drive heads north on Main Road toward US 17, the improvements are scheduled and paid for. If it runs down Bohicket toward Kiawah, nothing is scheduled.

The Maybank side is finished at one end

The northern pitchfork, the new connector between Maybank Highway and River Road, has been open since March 26, 2024. It was always meant to be half of a pair. When the County picked the "Town & Country" alternative in 2009, the plan called for both a northern and a southern pitchfork. In 2014, the County's project history records that the southern pitchfork's environmental impacts kept the design from meeting FHWA standards, and total funding dropped from $30 million to $15 million.

What remains in that budget today is small. According to the County's Maybank Highway project page, about $1.8 million is left, and the County has authorized it for designing a new outbound lane from River Road to the Stono River Bridge. Utility coordination and environmental permitting are underway, and the bid package is pending. That money pays for design. No construction funding for the lane has been identified.

The City of Charleston's priority list describes the southern pitchfork and roundabout as a way to potentially eliminate the traffic light at Fenwick Hall Allee, where the northern pitchfork meets Maybank, as reported by the Post and Courier. Seventeen years after the pitchfork pair was first chosen, the southern half still has no construction money.

What the November 3 ballot covers for Maybank

County Council adopted Ordinance 2398 on July 21, 2026. It names "Maybank Highway Southern Pitchfork and Roundabouts" among its featured projects, and the voter question repeats that name. The ordinance does not give an amount for each project. The County's funding allocation presentation, labeled "Draft as of July 21, 2026," lists the southern pitchfork and roundabout at $65,000,000. The same presentation lists a $5,000,000 roundabout at Main Road and Mary Ann Point. The spring draft reported by the Post and Courier also listed the southern pitchfork at $65 million.

The plan would borrow against expected tax collections so road projects can start sooner, rather than paying for them only as the money comes in. The 2024 referendum, which centered on the Mark Clark Extension, failed with more than 60% of voters opposed. The Post and Courier describes the Mark Clark as now considered dead. So the southern pitchfork is now the single largest Johns Island item in front of voters.

Either way, the result will be known within days of this post. Until then, the Maybank side's next big improvement has no funding. This is general information about a public measure, not legal, tax, or financial advice. If the vote affects a decision you're making, confirm the details with the right professional.

What the September numbers say about price

The road timeline sits alongside a detached-home market that has been giving a little ground. The Charleston Trident Association of Realtors' Johns Island Local Market Update for September 2026, current as of October 9, shows the single-family median sales price at $735,000. That is down 10.1% from $817,188 in September 2025. The average sales price moved the other way, up 4.6% to $996,031.

When the median falls and the average rises in the same month, the mix of homes that sold has shifted. Only 46 single-family homes closed that September. A handful of high-end sales pulls the average up while the median follows the middle of the pack. CTAR itself warns that its percent changes can look extreme because of small sample sizes. The year-to-date figures smooth that out. Through September 2026, the single-family median was $725,000, up 3.6%, and the average was $918,052, up 10.9%.

The figure that matters more for an offer is percent of original list price received. In September 2026, single-family sellers received 94.6% of their original asking price, down from 96.9% a year earlier. Homes took 57 days to sell, and inventory stood at 175 homes, compared with 187 a year before. CTAR notes that these figures do not account for sale concessions, so the real gap between asking and net price may be wider.

Townhouses and condos on the island are moving much faster. The attached median was $489,990 in September 2026, up 15.3% from a year earlier. Those homes sold in 15 days on average, at 99.0% of original list. Inventory also grew, from 21 to 36.

For a detached buyer this fall, that 94.6% figure means some room to negotiate off the original list price. A house whose daily route runs up Main Road to US 17 comes with a construction contract that runs through September 2028. A house whose route crosses the Stono on Maybank depends on how the November 3 vote turns out.

Frequently asked questions

Does the new roundabout change the Limehouse Bridge route? During the closure before the opening, the County directed River Road drivers to use Old Pond Road to Main Road to reach the Limehouse Bridge. The roundabout is part of Segment A, and the interchange work continues toward its 2028 completion date.

Is the Maybank outbound lane on the November ballot? The adopted 2026 list does not name it as a separate project. Its current funding is the roughly $1.8 million of remaining Maybank budget, which covers design.

Why read the single-family median with caution? In September 2026 it was based on 46 sales, and it fell in the same month the average rose. The year-to-date median of $725,000 is a steadier guide.
