State Road 32 Roundabouts (at SR38 and River Road)

State Road 32

*Conceptual rendering design, final design may be different*

PROJECT: Roundabouts at State Road 32/38 split and SR32/River Road

TIMELINE: Roundabout construction of SR32/38  was completed in 2022, and the roundabout of SR32/River Road will be substantially completed by the end of summer 2023.

PROJECT GOALS: Increased safety and mobility of the corridor.

OWNER: This is a joint project between the Indiana Department of Transportation and the City of Noblesville.


CONTRACTOR: Calumet Civil Contractors

SCOPE: Roundabouts at the intersections of State Road 32/State Road 38 split and SR32/River Road will replace traffic signals. A median will be placed between the two roundabouts, which will only allow for right in/right out movement at the entrances between the intersections. 

MILEAGE: 0.2 miles

ESTIMATED COST: $6.5 million

  • This is a matching partnership between INDOT and the City of Noblesville.

COUNCIL DISTRICT: 3 (Aaron Smith) and 4 (Dan Spartz)



On July 29, the State Road 32/River Road roundabout will be fully functional. The inner lanes will be closed from west of the 32/River Roundabout to west of 32/38, but will provide 1 lane of travel to remain open in each direction. This closure, which will likely last through August, is for the center median concrete work that was being used for traffic shifts while the roundabout was built. Additional finishing work will follow.
