Idaho State Police are still trying to figure out what caused a flatbed trailer being pulled by a pickup truck to flip over on Interstate 84 Monday morning — but say all four lanes of westbound traffic are now open by the Locust Road overpass now that the wreckage has been cleared away

The crash occurred just after 10 a.m. ISP officials are not sure if slippery, snow-covered roads were a factor. At one point, three of the four lanes of I-84 near milepost 45 were blocked to traffic but all lanes were reopened shortly after noon.

It appears no one was badly hurt in the crash.
