Kansas City and St. Louis Road Quality
Our roads are crucial for commerce, safety, and daily life. Yet the state’s extensive road network presents challenges that have lingered for years. The Missouri Department of Transportation (MoDOT) oversees approximately 34,000 miles of highways, making it one of the most extensive state-maintained systems in the nation. This vast responsibility is coupled with a perpetual struggle for adequate funding and consistent maintenance.
Missouri’s roads are often a mixed bag. Urban areas, such as Kansas City and St. Louis, face heavy traffic loads that strain infrastructure, while rural areas contend with neglect stemming from budget limitations. Harsh weather conditions further exacerbate the wear and tear, leaving many roads riddled with potholes and cracks. Rural highways critical for agriculture and trade can quickly deteriorate without sustained investment.
A recent post by the blog Construction Physics contained a chart depicting the road quality of the top 19 cities. It depicts the percentage of non-interstate roads at different quality levels, measured by the International Roughness Index (IRI) and tabulated by the Bureau of Transportation Statistics and Federal Highway Administration (FHWA). I’ve added St. Louis and Kansas City for comparison using the same scoring system.
Missouri’s interstates, whose standards and funding largely come from the federal government, rank 15th out of 50th according to the IRI score. But our non-interstate roads rank 32nd, behind our neighboring state of Kansas (1st) but well ahead of Illinois (37th). Kansas has earned a reputation for relatively well-maintained highways, thanks to strategic funding and regular maintenance schedules. Illinois has committed significant resources to upgrading its aging infrastructure through recent legislative initiatives.
Importantly, both Kansas and Illinois employ toll roads to fund road maintenance. Missouri should, too. Show-Me authors have written extensively on tolling and road maintenance more generally. While Missouri recently increased its gas tax, it’s too soon to know how impactful it will be.
Improving Missouri’s roads requires more than patchwork solutions. Lawmakers and transportation officials must focus on sustainable funding mechanisms, better prioritization of projects, and more efficient use of resources. Policies that balance the needs of urban centers and rural areas will be critical in ensuring that all Missourians benefit from reliable roadways.
