MERIDIAN, Idaho — A serious crash involving a dump truck caused major traffic problems in Meridian for most of the afternoon Friday.

The wreck happened around 12:15 p.m. on eastbound Interstate 84 at mile marker 46, just west of the Eagle Road offramp.

The two left lanes and the far right lane of eastbound I-84 were blocked, as was the far left westbound lane. The lanes were reopened just before 6 p.m.

ISP issued an update Saturday morning on the investigation into the truck crash:

Brian C. Smith, 35, of Boise, was on the left shoulder of eastbound I-84 in a 2019 Ford van with a flat tire. He tried to exit the interstate, crossing several lanes of travel.  

The van was struck by a 2008 Kenworth semi-truck and trailer traveling eastbound on I-84. The truck, driven by Lonnie R. Caldwell, 59, of Boise, hit the median jersey barrier and overturned, spilling a load of sand.

Caldwell was transported by ground ambulance to St. Luke's in Meridian.  

Smith and Caldwell were wearing seat belts.

MAP: Treasure Valley traffic 

The area was very congested, and traffic moved very slowly. Emergency responders were contending with multiple separate crashes between Locust Grove and the Cloverdale Overpass. 

Side streets also became congested as drivers try to find a way around the blockage. 

This is the second dump truck crash on I-84 in two days. A dump truck rolled near the Franklin/Caldwell exit Thursday morning, blocking lanes for hours and sending the driver to the hospital.
