Lake Murray looks permanent, the way lakes do. It isn't. Before 1930, the ground under that water held homes, farmland, six schoolhouses, three churches, and 193 graveyards, until the Lexington Water Power Company finished the Dreher Shoals Dam and backed the Saluda River up over all of it.
Roughly 5,000 people were relocated to make room for the reservoir. Car insurance in Lexington today covers the town that grew up on the shore their old communities left behind, and South Carolina's 25/50/25 liability floor doesn't care how the landscape got there.
A Dam Built to Power a Growing Town
The Dreher Shoals Dam was, at the time it was completed, the largest earthen dam in the world, built primarily to generate hydroelectric power for the surrounding area. It created Lake Murray, a 50,000-acre reservoir named for the project's chief engineer, William S. Murray, and its largest section still sits in Lexington County today.
The relocation that made room for it displaced entire communities, and the lake's reputation as a haunted or mysterious body of water traces directly back to the schools and churches and cemeteries that never got moved before the water rose.
What Lexington Drivers Are Required to Carry
South Carolina sets a 25/50/25 liability floor statewide: $25,000 in bodily injury coverage per person, $50,000 per accident, and $25,000 in property damage. Lexington drivers carry the same requirement as drivers anywhere else in the state.
- Liability: 25/50/25, mandatory statewide, unaffected by a town's size or history.
- Uninsured motorist: mandatory at the same 25/50/25 limits, since South Carolina skips a PIP mandate and relies on tort law instead.
- Underinsured motorist: optional, insurers must offer it but drivers can decline.
- PIP: not required or generally offered — South Carolina is a tort state.
Why Lexington Runs Above the State Average
Full coverage in Lexington averages around $247 a month, and liability-only policies closer to $148 a month — both above South Carolina's statewide figures of roughly $1,890/yr full coverage and $728/yr minimum coverage. That gap tends to track household income and home values, which in Lexington sit well above the state median.
Higher-value vehicles cost more to repair or replace, and that shows up directly in comprehensive and collision premiums rather than in the liability minimums, which stay fixed no matter which town a policy is written in.
US-378 Carries Downtown's Traffic
US-378 connects to I-20 at exit 61 and runs straight into Main Street, making it the primary route for commuters and shoppers heading downtown. That corridor has only gotten busier since the town opened the Icehouse Amphitheater on Main Street about a decade ago, a deliberate push to bring foot traffic — and the cars carrying it — back into the historic district.
A revitalized downtown is good for the town's tax base. It also means more stop-and-go traffic funneling through a fixed set of intersections during events, which is exactly the kind of pattern that builds into a corridor's claims history over time.
From Under 1,000 People to a County Seat
Lexington has been the seat of Lexington County since 1820, but its modern shape is much newer. The town counted fewer than 1,000 residents in 1970 and passed 20,000 by the 2020 Census, growth driven largely by the school system's reputation, easy highway access, and the pull of lakefront living that didn't exist before the dam went in.
None of that changes the coverage South Carolina requires on paper. A town built on relocated ground, with a lake hiding what came before it, is still worth a fresh quote rather than a rate assumed from a flatter, cheaper part of the Midlands.
