Construction to start at Bretzville Junction roundabout project near Jasper
Drivers at Bretzville Junction will face lane closures first, with roundabout work set to start around June 29 near Jasper.

Drivers who use the SR 64 and SR 162 crossing at Bretzville Junction will be the first to feel the change, with roundabout construction set to begin on or around Monday, June 29, near Jasper. INDOT says the opening phase will include temporary widening and Phase 1 construction preparation, and traffic through the intersection will be reduced to one lane in active work zones with a flagger directing vehicles.
That setup will hit the daily traffic that moves through one of Dubois County’s busiest junctions. Morning commuters headed into Jasper, school buses, delivery trucks and drivers stopping at nearby businesses should expect slower trips and backups once lane closures start in all directions. Anyone moving between the SR 64 corridor and the SR 162 approach should plan extra time through the area.

The work will replace the current signal-controlled intersection with a single-lane roundabout. Project messaging says the redesign is meant to improve safety and traffic flow at the Bretzville Junction crossing, which has long carried steady traffic near Jasper.
The project has been on the county’s radar for some time. INDOT first announced the Bretzville Junction improvement in 2022, later said construction would start in spring 2025 and open in 2026, then pushed the start into 2026 after re-engineering the roundabout plan. The latest schedule now points to late June, putting the first cones and lane shifts just ahead for drivers who use the corridor every day.
