At least one person died overnight Tuesday after a crash inside the roundabout at 96th Street and Allisonville Road in Fishers, Indiana, and the intersection remained closed early Wednesday while investigators worked to piece together what happened. Fishers police have not released the identity of anyone involved, how many people were hurt, or what caused the wreck. The shutdown closed one of Hamilton County's busiest commuter crossings for hours overnight.
Few Details, Two Different Timelines
According to WIBC 93.1 FM, Fishers police said officers were called to the crash around 11:40 p.m. Tuesday. WTHR placed the crash closer to 11:30 p.m., reporting that two vehicles collided directly with each other inside the double-lane roundabout. Neither outlet has said which vehicle struck the other first or whether speed played any role.
A Roundabout With A Rocky Two-Year History
The crash landed at an intersection that has drawn scrutiny since it was rebuilt. Fishers opened the double-lane roundabout at 96th Street and Allisonville Road on October 29, 2024, replacing an 11-year-old 'Michigan Left' design meant to ease congestion at the city's southern border, according to WTHR.
Crash rates spiked at the intersection soon after it opened, prompting Fishers to add lane markings, signage, and night lighting that weren't part of the original project, according to Indianapolis Business Journal. Drivers had complained about confusing multi-lane entry points and poor visibility, the outlet reported in January 2025.
Fishers Scraps A Second Roundabout After The Fallout
The spike in wrecks was serious enough to reshape the city's broader road-engineering plans. IndyStar reported in 2025 that Fishers scrapped plans for a similar roundabout further north at 116th Street and Allisonville Road, opting for standard lane improvements instead.
The intersection remains one of Hamilton County's heaviest commuter corridors. Roughly 58,000 vehicles pass through 96th Street and Allisonville Road every day, and that volume jumped about 20% in late 2024 as drivers detoured around Interstate 465 construction, per Indianapolis Business Journal traffic data.
Construction Still Active Along The Corridor
The roundabout also sits inside an active work zone. Fishers launched a $12.4 million infrastructure investment package for the 2026 construction season that includes corridor and safety improvements along Allisonville Road running through October, WTHR reported in June.
As of the week of August 3, the City of Fishers Department of Public Works listed several active roadwork projects and lane restrictions along Allisonville Road, including single-lane restrictions at 116th Street and temporary restrictions near 111th Street. The city publishes those updates weekly to warn commuters of potential delays.
Countywide Crash Numbers Underscore The Stakes
The fatal crash adds to a grim countywide trend. Hamilton County recorded 8,246 total vehicle crashes and 25 traffic fatalities in 2023, up from 18 fatalities the year before, according to Indiana University Public Policy Institute data.
State and local agencies have been working to address that risk. The Hamilton County Prosecuting Attorney's Office participates in state-funded Traffic Safety Division programs that target high-risk intersections, speeding, and aggressive driving, according to the Indiana Criminal Justice Institute's FFY 2025 Annual Report. Hamilton County's sheriff's office has also run a targeted crackdown further up Allisonville Road in response to high crash volumes.
What Investigators Still Don't Know
Fishers police haven't said what caused the two vehicles to collide inside the roundabout, whether speed or impairment played any role, or whether the crash will trigger a formal review of the intersection's design. Those questions remain unresolved as the investigation continues. Should the crash lead to civil litigation, serious motor vehicle cases originating in Fishers fall under the jurisdiction of the Hamilton County Government's Superior Court, located about 12 miles north in Noblesville.
