Traffic is flowing freely again on westbound I-694 in Vadnais Heights, but that was not the case earlier.
Commuters faced long delays Thursday morning as crews worked to clear a crash in which a semitrailer truck rolled over on westbound I-694 in Vadnais Heights.
The semi tipped over and spilled diesel around 4:30 a.m. near Edgerton Street and had the right three lanes closed for most of the morning rush hour, Minnesota Department of Transportation traffic cameras showed.
For a while, the ramp from southbound I-35E to westbound I-694 was closed, but that reopened around 8 a.m. The crash and ramp closure caused a four-mile backup that had traffic stacked up to Hwy. 36.
It was not immediately clear what led to the crash, but roads were partially snow covered at the time of the wreck.
