INTERSTATE 57: Expanding a Critical Link in the National Freight Network Building Better Roads: I-57 Expansion Powers Southern Illinois’ Future As one of the nation’s key freight corridors, Interstate 57 (I-57) plays a necessary role in moving goods and connecting communities. Recognized by the U.S. Department of Transportation as part of the National Highway Freight Network (NHFN), I-57 supports the efficient flow of commerce through Illinois and beyond. Now, with a 6-lane expansion project underway, this essential stretch of roadway is poised to deliver safer, faster, and more reliable transportation for travelers and businesses alike.
Expanding Capacity, Enhancing Safety
Connecting Communities and Commerce At its core, the I-57 expansion is about more than just moving vehicles— it’s about connecting people, communities, and businesses. Whether it’s ensuring fresh produce reaches grocery store shelves, helping local manufacturers deliver goods on time, or allowing families to travel safely, I-57 is a lifeline for Southern Illinois and beyond. By investing in the future of this critical corridor, Illinois is paving the way for safer roads, stronger communities, and a thriving economy. The improvements to I-57 reaffirm its role as a highway of opportunity—a road that not only connects cities but builds bridges to a better future.
Currently, this 52-mile stretch of I-57, running from I-24 near Marion (milepost 44) to I-64 north of Mt. Vernon (milepost 96), handles an average daily traffic (ADT) volume of 40,000 vehicles—35-40% of which are trucks. That’s 15,000 semi-trucks rumbling through each day. IDOT’s I-57 expansion project will add a third lane in each direction, resurface existing lanes, and install a median barrier to prevent head-on collisions. Additional improvements include updated guardrails, rumble strips, raised reflectors, and enhanced drainage systems. Together, these upgrades aim to reduce congestion, enhance freight reliability, and—most importantly—improve safety.
So, the next time you hit the road on I-57, take a moment to appreciate the journey ahead—and the hard work that keeps it moving forward.
The project’s significance extends beyond logistics—it’s about unlocking economic potential for rural Southern Illinois communities. By reducing the cost of freight transportation and improving access to reliable infrastructure, the expansion project strengthens the region’s competitiveness on a national scale.
