Chinden Boulevard has been reopened in both directions between Eagle Road and Discovery Way after a crash at Chinden and Park Meadow Way, Boise police say.
Six vehicles were involved, and there were minor injuries, police said. Four cars sustained enough damage that they needed to be towed.
The report was called in at 4:50 p.m.
There was also a minor rear-ender, with no injuries, on Chinden near Eagle.
All lanes of Interstate 84 are back open at Exit 42 - between the Meridian and Ten Mile Road exits - after a crash reduced travel to three lanes in both directions.
Drivers are no longer being asked to avoid Cloverdale Road and Hickory Drive in Boise after a three-car wreck.
