Willie Simmons – chair of the Mississippi Transportation Commission – and Brad White, executive director of the Mississippi Department of Transportation, recently announced two major expansion projects; one on I-55 in Madison County and the other on State Route 25 in Rankin County.

The announcement comes after the passage of House Bill 1938 during the 2026 regular session of the state legislature, which appropriated funding for those two capacity projects, which will help address traffic demands while improving safety and supporting continued economic development in two of Mississippi’s fastest growing regions.
The first project calls for the widening of I-55 by adding a lane in each direction between State Route 463 and Gluckstadt Road in Madison County – expanding the corridor from four to six lanes and installing interstate lighting inside the project limits.
The second project will widen SR 25 to six lanes from Grant’s Ferry Road to State Route 471 in Rankin County and includes the construction of roundabouts at the SR 25 and SR 471 interchange.
“Both of these projects are much needed,” Simmons said in a statement. “We are very pleased to be in the position where we are going from kicking the can down the road to actually preparing to let and build these projects in a manner that takes care of our communities – the business community, the emergency responders’ needs and all the individuals that travel these corridors.”
Officials say the investments will strengthen commerce, improve daily commutes and position Central Mississippi for future growth, with construction timelines and additional project details to be announced as planning and development move forward.
