Mankato, MN (May 16, 2026) – Several vehicles were involved in a chain-reaction crash on Friday afternoon, May 15, on the northbound ramp from Riverfront Drive to Highway 169 in Mankato.
According to the Minnesota State Patrol, the crash occurred at approximately 2:01 p.m. when a Kia traveling northbound on the ramp slowed for traffic ahead. A Chevrolet Bolt traveling behind the Kia then collided with it.
Investigators said the initial impact contributed to a series of rear-end collisions involving multiple vehicles that were also stopped or slowing on the ramp. A Chevrolet Malibu was stopped due to an earlier crash ahead when it was struck by a Chevrolet Impala traveling behind it. A Ford was also stopped in traffic on the ramp when a Chrysler traveling behind it collided with the Ford.
Emergency units responded to the scene along with Mankato Police and Mankato Fire Department crews. Authorities confirmed that injuries were reported, though the number and severity of those injured have not been released.
Road conditions were reported as dry at the time of the crash. Vehicles remained in the roadway as responders worked to clear the scene and assist those involved.
The incident remains under investigation.
We are thinking of those injured as they recover.
What Often Leads to Chain-Reaction Crashes on Highway Ramps?
Chain-reaction crashes on highway ramps commonly occur when traffic slows suddenly, and drivers are unable to stop in time. Limited space on ramps can increase the likelihood of multiple rear-end impacts occurring in quick succession.
Investigators often review traffic flow, stopping distances, and driver reaction times when examining these types of collisions. Even a single initial impact can trigger additional crashes when vehicles are closely spaced. Ramp congestion, merging traffic, and reduced visibility can also contribute to sudden slowdowns. Vehicle damage patterns and roadway positioning help determine the sequence of impacts and how the collision developed across multiple vehicles.
