A semitrailer truck rolled over Saturday morning on northbound Interstate 35W on the south edge of downtown Minneapolis, snarling traffic heading into downtown.

The truck was lying on its side under the Portland Avenue overpass, near where I-35W makes a sharp turn to the east to run alongside Interstate 94. The State Patrol closed northbound I-35W at the downtown exits, and traffic was backed up into south Minneapolis as far as 40th Street.

Demitrius Goudeau, of Gulfport, Miss., was driving the RWI Transportation truck. Goudeau, 38, was transported to Hennepin County Medical Center where he remains in satisfactory condition, hospital officials said.

By 4:15 p.m., MnDOT cameras showed traffic back to normal.
