La Porte County, IN – Drivers traveling through northwest Indiana are being urged to avoid U.S. Highway 421 today after a crash prompted a full road closure near the Indiana Toll Road and Interstate 94.
According to the La Porte County Sheriff’s Office, deputies are investigating a traffic crash near County Road 100 North on U.S. 421. The highway is closed between the Indiana Toll Road and I-94 as first responders work the scene. Authorities say INDOT Northwest is assisting with traffic control and road conditions.
Officials report near-whiteout conditions in some areas, raising safety concerns for motorists and slowing emergency response efforts. Drivers are being asked to seek alternate routes and delay travel if possible while the investigation and cleanup continue.
The closure impacts a key north-south corridor frequently used by commuters, commercial drivers, and travelers connecting between I-94 and the Indiana Toll Road. No estimated reopening time has been announced, and officials have not released details on injuries or the number of vehicles involved.
Weather conditions in the area may be contributing to hazardous driving conditions, and authorities remind drivers to reduce speed, increase following distance, and use headlights when visibility is low.
Traffic delays are expected throughout the surrounding area, including parts of northern La Porte County and nearby routes feeding into I-94. Motorists should monitor INDOT traffic updates and local law enforcement advisories before heading out.
