BOISE, Idaho — Two people were taken to Boise hospitals after a driver crashed into nine other vehicles on the I-184 Connector Thursday afternoon, police said.

According to Idaho State Police, 19-year-old Brigham B. Anderson, of Meridian, was driving west in a Toyota Camry when he left his lane and struck nine vehicles.

The crash, reported to police at about 4:20 p.m., blocked westbound lanes near the Maple Grove overpass for a couple hours while crews worked to clear the scene. Westbound I-84 was backed up for miles and the Connector came to  a standstill.

Two people, including Anderson, were taken to the hospital to be treated for injuries.

The crash remains under investigation. At this point, there is no word on what caused Anderson to crash into the other drivers.

Just as traffic was beginning to move again, there were reports of two more crashes on I-184 near Chinden Boulevard. The two right lanes on the outbound Connector were blocked for more than an hour while crews cleared the scene.
