The National Bikers Roundup, one of the country’s largest motorcycle rallies, is going to take place Aug. 2 through 6 at Thunder Valley and Valley Speedway in Grain Valley.

The five-day rally is expected to attract approximately 20,000 members of motorcycle clubs from around the United States. The Roundup offers a variety of entertainment including concerts, games, DJ tents, parades, stunt shows and drag racing.

The cost to attend is $30 for the entire week, which includes an arm band that will be worn for admission to the events and activities. Organizers of the event will be collecting monetary donations and non-perishable food items to be donated to the Grain Valley Assistance Council and Harvesters.

The Grain Valley Police Department advises that residents should anticipate some traffic congestion throughout the duration of the Roundup. They are in coordination with other law enforcement agencies to assist in traffic control. It is likely that there will be officers from Missouri State Highway Patrol, Jackson County Sheriff, Oak Grove Police Department and other agencies present in the community throughout the week. 

During the event, Old Highway 40 East of Buckner-Tarsney Road to Monkey Mountain will be closed to all through traffic except emergency vehicles. Additionally, on-street parking will not be permitted on Harris Street, east of Main Street.
