Progress is underway! Early Phase 3A construction has begun.
These utility relocation activities will prepare the area for major construction starting in 2027 and help lay the groundwork for the next phase of improvements.
Crews recently completed a drilled shaft pour, an important part of constructing the deep foundations that support future bridge structures across Phase 3C of the Carolina Crossroads Project.
Partial demolition of the existing I-20 westbound bridge over the Saluda River helped clear the way for construction of the new bridge adjacent to the current structure.
This marked another important step in the project's transformation of the corridor.
Cranes are on site as crews prepare to place barges in the Saluda River for upcoming Phase 3C construction activities on the Carolina Crossroads Project.
The barges will provide access for work in and around the river as improvements continue throughout the corridor.

Crews are hard at work replacing four bridges over the Saluda River and CSX railway on I-20.
This bridge work and the visible road construction work between Exits 61 (Sunset Boulevard) and 63 (Bush River Road) are part of Phase 3C of the Carolina Crossroad Project.
Remember, more than cars and SUVs use our roads to get to where they’re headed.
On or off the highway, if you see a school bus, remember to drive with extra caution, keeping a sharp eye on the bus and its surroundings.
Take a look back at the I-26 bridge over the Saluda River in 1959.
Since then, the corridor has continued to progress over the years to meet the state's transportation needs.
Phase 3C construction is underway! Watch for changing traffic patterns in work zones.
Slow down and stay alert for crews on site.
The Carolina Crossroads Project is bringing long-term improvements to one of South Carolina’s busiest interstate corridors.

Carolina Crossroads puts safety and efficiency first.
The project remains committed to SCDOT’s promise to provide a more reliable transportation network across South Carolina for generations to come.

Diverging diamond interchanges (DDI) improve traffic flow by briefly shifting vehicles to the opposite side of the road so drivers can make left turns without crossing oncoming traffic.
Check out how to navigate the DDI on Phase 2.

Carolina Crossroads is more than highway construction, it’s a major infrastructure project with care, collaboration, and South Carolina’s future in mind.
