I-35 is Harrison County's main artery and weather chokepoint

Interstate 35 runs north-south through Harrison County, passing Bethany and continuing through Eagleville toward the Iowa state line. It is the county’s primary long-distance route and the reason Bethany functions as a highway service stop. Because I-35 crosses open northern-Missouri farmland, winter storms can bring blowing and drifting snow, ice, and occasional closures, and a major interstate closure can ripple into local roads. Before traveling in bad weather, check MoDOT’s traveler information map for road conditions, work zones, and winter reports rather than relying on a single forecast. For long trips, knowing whether I-35 is open at the Iowa line matters as much as the local forecast.
