Replacing deteriorating drainage structures across two Indiana counties is the focus of new work underway by Superior Construction for the Indiana Department of Transportation’s Crawfordsville District. The company announced the project starts on Oct. 3, 2026, with construction taking place in Montgomery and Putnam counties.
The work addresses aging pipe infrastructure beneath state highways and is intended to improve drainage performance and long-term durability. Both projects are being delivered by Superior Construction’s Mid-south Heavy Civil business unit, led by Division Manager Tim Koster.
Near McFarland Ditch along State Road 32, Superior Construction is replacing two deteriorated metal pipe culverts with a 48-foot precast concrete box culvert. Rust and wear had weakened the existing pipes, while a recent flood event increased the urgency of the replacement.
The new structure is designed to carry more water and help reduce upstream flooding in the surrounding rural area. Superior’s crews are performing excavation, embankment work and culvert installation during a planned 60-day road closure.
The construction sequence must account for changing weather conditions, particularly rainfall that could affect excavation and drainage work.
In Putnam County, the contractor is replacing seven corrugated metal pipe crossings beneath a three-mile stretch of US 231, a key route between Greencastle and Interstate 70. The existing pipes will be replaced with reinforced concrete pipe designed to resist corrosion and provide long-term service.
Because the corridor serves nearby homes, businesses and a hospital, the project team is using flagging operations for much of the work to reduce the need for lane closures. Before construction began, the team also coordinated with 18 homeowners and two businesses to help maintain access to properties.
Drainage structures play an important role in roadway performance, flood management and public safety. Replacing corroded culverts can improve water conveyance and reduce the risk of infrastructure deterioration disrupting road operations. These Indiana projects also illustrate how contractors must balance construction sequencing and traffic control with the needs of residents, businesses and essential services.
