Two crashes on northbound Interstate 5 in Federal Way caused lengthy back-ups Thursday morning.
All lanes have re-opened to traffic.
The crash on South 272nd Street happened just before 4:30 a.m., according to the Washington State Department of Transportation. The collision blocked several lanes and caused a 10-mile back-up at one point. It took nearly five hours to clear that crash.
A second crash involving five vehicles happened about 9 a.m. north of South 317th Street, about one mile south of the earlier crash.
The suspect vehicle reportedly sped up the left shoulder before the crash, according to Washington State Patrol Trooper Rick Johnson. Both people inside the car fled after the crash and were since taken into custody.
Two people had minor injuries, and one person has serious but non-life threatening injuries, according to Johnson. One person was extricated from a vehicle, according to South King Fire & Rescue.
Several agencies responded to the second crash, including South King Fire & Rescue, Puget Sound Regional Fire Authority, Valley Regional Fire, Federal Way Police, and Washington State Patrol.
