News Summary
Missouri is undergoing its busiest construction season, with over 1,000 active work zones statewide. The Department of Transportation is focusing on major projects like Improve I-70 and Forward 44, which aim to enhance traffic flow and safety.

MoDOT is taking steps to manage disruptions and prioritize worker safety amidst these initiatives.
Missouri is experiencing its busiest construction season this year, particularly noticeable as the last holiday weekend of the summer approaches. Currently, there are over 1,000 active work zones state-wide on any given day, significantly impacting traffic patterns and driver convenience.
The Missouri Department of Transportation (MoDOT) is embarking on its most ambitious construction projects to date, notably the Improve I-70 initiative and the Forward 44 project. The Improve I-70 project alone will cover over 200 miles and is making rapid progress through simultaneous operations across multiple sections of the highway. The overarching goal is to enhance the highway by adding a third lane between St. Louis and Kansas City, which is essential for accommodating the growing traffic demand across this major route.
Drivers Advised to Exercise Caution
With such extensive construction underway, MoDOT has emphasized the importance of following posted speed limits and exercising caution in construction zones. Ongoing projects are expected to extend over the next few years, with significant disruptions anticipated, particularly near major urban centers such as St. Louis, Columbia, and Kansas City.
Project Details and Traffic Management
Travelers should be especially mindful of potential delays when traveling between critical areas such as Columbia to Kingdom City, Wentzville to Warrenton, and Blue Springs. MoDOT is strategically scheduling much of the construction during off-peak hours, including overnight work, to diminish traffic disruptions. Moreover, adjustments will be made to accommodate game days for college football fans beginning in August, ensuring that lane closures are minimized during major events.
Safety and Worker Support
Amidst these extensive projects, MoDOT faces staffing challenges for its workforce, though recent pay raises have bolstered recruitment and retention efforts. These adjustments are meant to maintain a robust team to manage the dual challenges of increasing work zones and the need for safety. With safety at the forefront, MoDOT aims for zero fatalities during the construction period, especially given the dire statistics from last year that reported 10 fatalities and 83 serious injuries during the Memorial Day holiday.
Future of I-70 Construction
The completion target for the entire Improve I-70 project is set for the end of 2030. The improvements are part of a broader vision to enhance infrastructure across the state, acknowledging that a safer, more efficient I-70 will support both tourism and local traffic. MoDOT is committed to ensuring the cooperation of motorists to create a safe working environment for highway workers and road users alike.
