Duncan, SC – The planned closure of the SC Highway 290 bridge over Interstate 85 in Duncan has been postponed due to anticipated rain in the coming days. Originally set to begin on May 2 at 7 p.m., the closure is a part of the ongoing construction project by the South Carolina Department of Transportation (SCDOT) aimed at developing a diverging diamond interchange at this crucial junction.

Officials from SCDOT indicated that dry weather is essential for the successful completion of road paving projects, leading to the decision to delay the bridge closure. The agency is currently in the process of rescheduling the necessary closure to resume work on the interchange redesign as soon as conditions permit.

The SC Highway 290 and I-85 interchange project is designed to help ease congestion in a heavily trafficked area that connects Spartanburg and Greenville. The diverging diamond configuration, which will be the third of its kind in South Carolina, is intended to improve traffic flow and safety by allowing vehicles to switch to the left side of the road before returning to the right. This design helps reduce traffic signals and allows for better movement through busy intersections.

Motorists may find it challenging to navigate the diverging diamond layout at first, but SCDOT has made resources available on its website to assist drivers in understanding how to maneuver through the new configuration. It is crucial for those traveling in the area to pay attention to posted detour signs during the closure, which will remain in effect until all construction work is completed.

Final tasks for the interchange include pavement markings and adjustments to traffic signals, both of which are critical for ensuring the safety and effectiveness of the newly designed interchange. The completion of this project is anticipated to substantially enhance traffic conditions, making commutes more efficient for local drivers.

The bridge closure was part of a broader initiative to improve infrastructure and manage increasing traffic volumes in the area. Understanding the diverging diamond interchange will be vital for area residents and frequent commuters who rely on SC Highway 290 and I-85 for travel.

As SCDOT continues to monitor weather conditions, updates regarding the closure’s new schedule will be shared through official channels. The agency is committed to ensuring that any disruptions to traffic are minimized, and public safety remains a top priority during the construction process.
