News Summary
The newly constructed I-20 bridges over the Savannah River and Augusta Canal have opened to traffic after years of construction. This project, a collaboration between Georgia and South Carolina transportation departments, modernizes infrastructure to improve traffic flow and safety for nearly 70,000 daily vehicles. Costing approximately $83 million, the bridges feature updated safety standards and are designed to accommodate future growth. Despite delays from various challenges, the bridges are expected to last over 75 years, benefiting transportation in the Southeastern United States.
Augusta, GA – The long-awaited new bridges spanning the Savannah River and Augusta Canal on Interstate 20 have officially opened to traffic after several years of construction and delays. This significant infrastructure project, a first-of-its-kind bi-state collaboration between the Georgia Department of Transportation (GDOT) and the South Carolina Department of Transportation (SCDOT), replaces aging bridge structures that originally opened in the 1960s.
The new I-20 bridges are designed to enhance traffic flow, increase safety, and accommodate anticipated growth in the area until the year 2042. With six travel lanes, the modern structures meet updated safety standards, including a median barrier wall that separates oncoming traffic—key features expected to improve both the traveling experience and safety for the nearly 70,000 vehicles using the corridor daily.
The total cost of the project was approximately $83 million. To minimize disruption during the construction phase, which began in 2019, GDOT and SCDOT worked together to maintain two lanes in each direction on I-20. This strategic planning was essential to manage traffic flow while extensive work was carried out.
Alongside the bridge construction, the project involved a 1.8-mile widening of I-20 and improvements to the West Martintown Road Interchange in South Carolina. These upgrades are intended to ensure that the interstate can handle increased traffic volumes in the future as the region grows.
However, the path to completion was not without its challenges. Factors such as the ongoing pandemic, global supply chain issues, and difficulties related to managing the water flow in the Savannah River contributed to extended delays. Originally projected for completion in early 2025, various circumstances led to alterations in the timeline, with GDOT now anticipating that the final touches—like dressing slopes for erosion control and completing safety features such as cable barriers—will be finalized by January or February 2025.
Despite the setbacks, GDOT Communications Program Manager Kyle Collins confirmed that the new bridges are expected to have a lifespan of over 75 years. This longevity aligns with the region’s growing infrastructure needs and ensures that the new constructions will support travel and commerce for decades to come.
Looking ahead, as the project nears its final stages, the public can expect improved transportation conditions and a more safe and efficient travel experience on this major interstate route. The opening of the new I-20 bridges is a significant milestone not only for Georgia and South Carolina but for the future of transportation in the Southeastern United States.
