CASCO TOWNSHIP, MI — A stretch of northbound I-196 in Allegan County remained closed Monday afternoon after a crash involving a semi-truck and a Michigan Department of Transportation truck. The collision happened in Casco Township just north of the 109th Avenue exit, and deputies said cleanup work was still underway.

According to the Allegan County Sheriff’s Office, the crash happened around 2:40 p.m. No injuries were reported, but the semi jack-knifed into the median after hitting the MDOT vehicle. Drivers were being urged to avoid the area while crews worked to reopen the roadway.

Crash happened during MDOT patch work along the highway

Deputies said an MDOT crew was patching the highway when the semi hit the agency truck. That detail suggests the work zone was active at the time of the collision, although authorities have not said what led to the impact.

The truck involved in the state road work was part of a crew handling maintenance on the interstate. The semi’s movement after the impact left it jack-knifed in the median, adding to the shutdown on the northbound side.

MDOT crews and other responders were focused on clearing the scene so traffic could resume. No additional details were released about damage to either vehicle.

Allegan County deputies said no one was hurt

The Allegan County Sheriff’s Office said the crash did not leave anyone injured. That included workers at the MDOT site and the driver of the semi-truck, based on the information released Monday.

Even without injuries, the crash created a significant traffic disruption because the semi came to rest in the median and the northbound lanes were blocked. Incidents like this often require a full closure until the vehicles and debris can be removed safely.

Deputies did not immediately provide any report of citations, charges, or other enforcement action tied to the crash.

Northbound traffic was diverted while cleanup continued

By Monday afternoon, northbound I-196 was still shut down as crews worked at the scene. Officials asked drivers to steer clear of the area rather than try to approach the closure, a common step when responders need room to clear wreckage and complete cleanup.

The closure affected travelers heading through Casco Township in southern Allegan County. The location near the 109th Avenue exit meant motorists in the area had to look for alternate routes until the interstate could reopen.

Authorities did not give a timeline for reopening, saying only that the road would stay closed during cleanup.

What drivers in the area needed to know

The crash involved a state transportation vehicle working on a highway patching project, which made the closure especially disruptive for traffic on the busy interstate. Because the semi jack-knifed, the blockage extended beyond a simple lane issue and required more extensive scene management.

For drivers, the most immediate advice was to avoid northbound I-196 near the 109th Avenue exit until officials finished clearing the roadway. No detour details were provided, so motorists in the region had to make their own alternate plans based on local traffic conditions.

Authorities had not said whether the closure would last into the evening.

No further details released on cause of the collision

The sheriff’s office said the crash happened while work was being done on the interstate, but officials did not say why the semi struck the MDOT truck. At that point, the focus remained on cleanup and reopening the highway rather than assigning fault.

Because the collision happened in a work zone, investigators may continue reviewing the circumstances surrounding the impact. For now, the confirmed facts were limited to the location, time, vehicles involved, lack of injuries, and the ongoing shutdown of northbound I-196.

Officials did not release any additional information about the drivers or the condition of the MDOT crew members beyond saying no one was hurt.

Interstate remained blocked as responders cleared the scene

The shutdown underscored how quickly a work-zone crash can affect a major highway. Even though the collision did not cause injuries, the jackknife and the presence of an MDOT vehicle meant the scene needed careful cleanup before traffic could safely move again.

Northbound I-196 remained closed into the afternoon while responders handled that work. Drivers in Allegan County were told simply to stay away from the area until the roadway was cleared and reopened.
