Hundreds of motorcyclists will roll down Interstate 84 from Meridian to Mountain Home on Sunday for the 8th annual Patriot Thunder ride.
The ride is a fundraiser for military families, through the Idaho Guard and Reserve Family Fund and Operation Warmheart.
It's expected to begin at 11 a.m., with riders heading on to I-84 at the Eagle Road interchange, and will continue to Carl Miller Park in Mountain Home.
Idaho State Police troopers will escort the bikers.
To safely accommodate those participating in Patriot Thunder, law enforcement will reduce speeds and temporarily block access to eastbound I-84 between Nampa and Mountain Home, where the ride will conclude at about 12:30 p.m.
On-ramps from Garrity Road to Exit 95 in Mountain Home will be temporarily blocked, as will Franklin Road, the Wye Interchange (I-84/I-184), and the I-184 connector between 13th Street and I-84.
As the motorcade approaches each on- and off-ramp, members of the traveling public will not be permitted to enter, join or pass the motorcycle procession.
Regular traffic flow is expected to resume by 1 p.m.
