Rock Hill is building the infrastructure to support its position as Charlotte’s fastest-growing southern suburb. A $106 million I-77 interchange upgrade, a Catawba River bridge renovation, a $14.9 million stormwater project, and new business parks representing $270 million in development. For a city gaining 5,000 new residents per year, these investments are essential — and they’re happening now.
-
I-77 is primary corridor: I-77 improvements directly support Rock Hill growth as Charlotte satellite. This is critical infrastructure for market viability. -
Commuter rail uncertainty: Piedmont commuter rail is multi-state, federally-funded project. Rock Hill inclusion is still being planned. -
Residential demand driver: I-77 improvements support commuter accessibility, which is the primary driver of Rock Hill residential demand. -
Industrial secondary: Industrial growth in Rock Hill depends on I-77 corridor for regional market access.
I-77 Exit 82 upgrade: $106 million
| Project | Cost | Details |
|---|---|---|
| I-77 Exit 82 interchange | $106M | York County contributing $11M |
| Catawba River Bridge (I-77 south) | $50M+ | Major renovation underway |
| Stormwater infrastructure | $14.9M | ARPA-funded, completion Fall 2026 |
| Celanese Road widening | $25M+ | 4-lane divided, supporting growth |
The I-77 Exit 82 interchange is the main gateway to Rock Hill from Charlotte. The $106 million upgrade adds capacity at the interchange that serves the growing commercial and residential corridors east and west of the interstate. York County is contributing $11 million to the project, which tells you the local government sees the return on investment. When you’re gaining 5,000 residents a year, the roads have to keep up.
What I-77 improvements support
- I-77 capacity expansion reduces commute times from Rock Hill to Charlotte
- Improved Charlotte accessibility makes Rock Hill attractive for commuter-dependent residents
- Industrial access improvements support manufacturing and distribution growth south of Charlotte
- I-77 improvements are confirmed highway projects with committed funding
- Rock Hill benefits from Charlotte growth spillover as I-77 access improves
What creates timing and demand risk
- Commuter rail planning is early-stage and may not include Rock Hill as planned stop
- I-77 improvements are multi-year projects; not all phases complete simultaneously
- Residential demand depends on continued Charlotte growth; slowdown reduces Rock Hill demand
- Industrial growth depends on I-77 access, which is still under improvement
Catawba River Bridge renovation
The Catawba River Bridge on I-77 south is undergoing a major renovation. This bridge is the connection point between Mecklenburg County (Charlotte) and York County (Rock Hill/Fort Mill). It carries tens of thousands of commuters daily in both directions. Lane closures during construction have been disruptive, but when complete, the bridge will handle the growing cross-border commuter traffic more safely and efficiently.
The bridge is symbolic of something bigger: the Mecklenburg-York County corridor is one of the fastest-growing cross-border commuter zones in the Southeast. More lanes on this bridge directly support the commercial property demand driven by Charlotte spillover.
Business park development
Legacy West and Legacy East are two business parks being developed along I-77 in Rock Hill. Combined, they could bring $270 million in investment and 1,850 jobs. Legacy West includes two speculative buildings, one at 430,000 square feet. This is the kind of development that signals institutional confidence in the Rock Hill industrial market.
Add the Pallidus semiconductor campus ($443M, 405 jobs) and the Knowledge Park redevelopment downtown (400,000 SF of adaptive reuse), and you have a city that’s building significant commercial infrastructure. As we noted in the Rock Hill growth drivers article, the combination of Charlotte proximity and SC tax advantages is a powerful draw.
Stormwater and utility infrastructure
The South Carolina Office of Resilience awarded Rock Hill $14.9 million in ARPA funds for stormwater improvements in the South Central and Flint Hill neighborhoods. Construction is estimated at 300 days with completion in Fall 2026. Improved drainage infrastructure makes adjacent commercial parcels more developable and reduces flood risk for existing properties.
York County’s utility infrastructure is also expanding. Catawba Water (formerly York County Water & Sewer) is investing in capacity upgrades to serve the growing population and commercial demand along the I-77 corridor. Reliable water and sewer service is critical for industrial tenants and manufacturing operations.
Celanese Road and Dave Lyle Boulevard improvements
Celanese Road is being widened to a four-lane divided highway in sections, accommodating growth in the western Rock Hill submarket. Dave Lyle Boulevard, which connects I-77 to the growing east side of Rock Hill, has seen intersection improvements and access management upgrades. These corridors carry commercial traffic to retail centers, flex parks, and storage facilities.
Impact on property values
The I-77 interchange upgrade directly benefits the Rock Hill market by improving truck access and commuter flow. The business parks create new inventory and validate the market. Improved stormwater and utility infrastructure opens up land for future commercial development.
If you own property in Rock Hill or York County, these infrastructure investments are supporting the growth that’s already happening. The roads, bridges, and utilities are catching up to the demand. That’s a positive signal for property values.
Seller takeaway
Rock Hill infrastructure is making the market more accessible to Charlotte commuters. I-77 improvements are the foundation. Position your property to benefit from commuter accessibility. Call Roth Capital at 704-600-3839 to discuss your Rock Hill property and I-77 corridor development.
