States in the path of totality for the solar eclipse have been hit with “major traffic delays” thanks to an influx of travelers to the areas. 

Roads and highways in Texas, Ohio, Illinois, Michigan, Indiana, Vermont and New Hampshire were reportedly experiencing a flood of motorists from out of state, reported USA Today.

Oklahoma officials reported that a 7:30 a.m. crash on Interstate 40 at mm 261, west of Checotah in McIntosh County, was blocking traffic in southeastern Oklahoma near several state parks that were hosting eclipse viewing events in the path of totality.

“Crews estimate cleanup will take the majority of the day. Expect delays in the area and use extra caution,” the Oklahoma Department of Transportation wrote on social media. 

Multiple crashes along Interstate 35 in Waco, Texas near FM 1242 and CR 2341 were also blocking traffic by Monday morning, causing traffic jams near more eclipse events due to lane shut downs. 

“Expect major traffic delays in this area,” the Texas Department of Transportation wrote. 

Some state governments banned oversize loads from traveling on the day of the eclipse, and others advised truckers to take a ‘holiday’ to avoid the delays. The 2017 solar eclipse saw backups last for as long at 13 hours after the event.
