The 54-year-old driver of a semi truck was taken to Harborview Medical Center with a broken leg and lacerations after he rolled his truck on the onramp to southbound Interstate 5 from the West Seattle Bridge this morning.

The State Patrol said that it appears the truck was going too fast around a curve, causing his 18-wheeler to tip over and wedging the truck's trailer in an triangle-shaped opening between the ramp and the roadway at 10:34 a.m.

No one else was injured in the crash, said Seattle Fire Department spokeswoman Helen Fitzpatrick.

Right after the crash, the onramp and the two right lanes of southbound I-5 were closed at Spokane Street. The state Department of Transportation reopened the center lane at 11:47 a.m., said spokeswoman Myly Posse. Traffic was backed up for approximately four miles, she said.
