UPDATE 6:30 p.m.
Ada County Sheriff's Deputies have reopened Highway 55 in both directions. Winds whipped flames from a car fire to a field just north of the Avimor development. After closing the road to traffic in both directions, eventually one lane was opened late Tuesday afternoon, and deputies finally determined that traffic could safely resume in both directions.
The 90-degree-plus temperatures plus high winds aren't making things any easier for fire crews currently battling a blaze along Highway 55, north of Avimor. Ada County Sheriff's deputies have shut down Highway 55 in both directions and drivers are encouraged to avoid the area.
Deputies and firefighters hope to move traffic as soon as it's safe but it will likely be reduced to one lane for a while.
