BOISE -- Scattered snow showers and slick roads appeared to contribute to a wave of crashes Wednesday.
Vehicles began to crash and slide off Interstate 84 around 9 a.m. near the Ada and Canyon County lines.
At least three crashes, including a rollover, were reported to Idaho State Police in the area of Ten Mile Road to the Karcher Road exit on I-84.
Later in the morning, crashes near Eisenmann Road and Vista Avenue on I-84 also caused problems.
The Ada County Sheriff's Office reports from 7:30 a.m. to noon there were 59 crashes just in Ada County. Six of those were injury crashes.
A crash on Five Mile and Franklin roads Wednesday afternoon shut down the traffic signal in that area and caused some major backups.
Shortly before 4 p.m. there was a report of a crash on Eagle Road involving a school bus and a pickup truck. Authorities say the bus was waiting to turn west on Island Woods Drive when it was struck by the truck. There were children on the bus, but we are told everyone is OK. The driver of the pickup, a 32-year-old Nampa woman, was cited for driving too fast for conditions.
In Boise, near State Street and Glenwood a car slid off the road, knocking over a cable line. It happened on State Street near the Plantation Country Club.
Idaho's Chief Meteorologist Rick Lantz says the snow will continue to fall and temperatures will not get above freezing. This is just the start of a wet pattern. Two to five inches of snow is expected to fall in the Treasure Valley between now and Saturday morning. Twin Falls could get up to eight inches of snow, and some mountain locations could get a foot of snow.
A Winter Weather Advisory is in effect for Boise and the West Central Mountains. The snow is expected to continue falling through Saturday morning.
The Idaho Transportation Department has crews working around the clock to keep our highways safe.
"We've been out on the roads since this started this morning, and we anticipate that we'll be out all night, overnight, getting ready for the morning commute," said ITD spokesman Reed Hollingshead. "We have the resources to do that. We have more than a dozen maintenance sheds in our district to handle this."
Idaho State Police are urging motorists to reduce their speeds and give yourself more time to get to your destination. Expect slick conditions on the roadways for Thursday morning's commute.
