Kansas City’s Road Diet Projects: How Lane Reductions on Southwest Trafficway, 33rd Street, and Linwood Boulevard Will Affect You
Kansas City is undergoing significant traffic infrastructure changes as three major roadways—Southwest Trafficway, 33rd Street, and Linwood Boulevard—prepare to implement “road diet” projects aimed at improving safety and reducing congestion. While these projects promise long-term benefits, they will temporarily disrupt daily commutes, emergency response times, and local businesses. Here’s what drivers, residents, and businesses need to know about the upcoming changes.
What Is a Road Diet, and Why Is Kansas City Implementing It?
A road diet is a traffic-calming strategy that reduces the number of lanes on a roadway, typically converting four-lane roads into two-lane configurations (one lane per direction) while adding features like bike lanes, turn lanes, or median buffers. The goal is to:
- Improve safety by slowing traffic and reducing the severity of collisions.
- Enhance pedestrian and cyclist access by creating dedicated spaces for non-motorized travel.
- Reduce congestion by encouraging more efficient traffic flow and discouraging cut-through traffic.
- Support local businesses by prioritizing access for delivery vehicles and emergency services.
Kansas City’s projects align with national trends, as cities like Portland, Oregon, and Austin, Texas, have successfully implemented similar initiatives to modernize aging infrastructure and adapt to evolving transportation needs.
Key Road Diet Projects in Kansas City
1. Southwest Trafficway: A Critical Corridor Under Construction
Southwest Trafficway, a major east-west artery in Kansas City, is set to undergo a lane reduction from four to two lanes in each direction, along with the addition of a center turn lane and potential bike lanes. While exact start dates are still being finalized by the City of Kansas City, Missouri, preliminary plans indicate construction will begin in late May 2026 and last approximately 6–8 weeks.
This project is part of a broader effort to address chronic congestion along Southwest Trafficway, which serves as a primary route for commuters, freight trucks, and emergency vehicles. The city has emphasized that detour routes will be clearly marked, and real-time traffic updates will be provided via KCMO’s transportation portal.
2. 33rd Street: Balancing Safety and Access
33rd Street, another high-traffic corridor, will see a similar road diet conversion from four to two lanes, with plans to include a dedicated left-turn lane at key intersections. This project is particularly relevant for businesses along 33rd Street, including retail stores and restaurants that rely on customer drop-off and pick-up services.
Concerns have been raised by local business associations about potential disruptions to delivery schedules, particularly for services like UPS, FedEx, and USPS. The city has committed to coordinating with logistics providers to minimize delays during peak shipping hours.
3. Linwood Boulevard: A Neighborhood-Focused Approach
Linwood Boulevard, a mixed-use corridor with residential, commercial, and industrial zones, will also undergo a lane reduction and traffic-calming modifications. Unlike the other projects, Linwood’s road diet will include speed humps and widened sidewalks to prioritize pedestrian safety.
Residents in the area have expressed mixed reactions, with some welcoming the safety improvements and others concerned about increased travel times. The city’s Public Works Department has scheduled community meetings in early June to address specific concerns and gather feedback.
How Will These Changes Affect You?
For Daily Commuters
- Increased travel times: Expect 10–20% longer commutes during construction, particularly during rush hours (7–9 AM and 4–6 PM).
- Detour planning: Familiarize yourself with alternate routes, such as 39th Street or Broadway, which may experience temporary congestion as a result of rerouted traffic.
- Real-time updates: Use apps like Google Maps or Waze for live traffic alerts.
For Emergency and Delivery Services
While road diets are designed to improve safety, they can initially slow response times for emergency vehicles and delivery trucks. The city has assured that:
- Emergency lanes will be designated where possible.
- Priority signals will be installed at intersections to expedite passage for fire trucks, ambulances, and police vehicles.
- Logistics coordination is underway with major carriers to adjust delivery schedules and routes.
For businesses relying on timely deliveries, the Kansas City Economic Development Corporation is offering resources to help mitigate disruptions.
For Pedestrians and Cyclists
These projects are a major win for walkers and bikers, with dedicated lanes and safer crossings planned along all three corridors. However, temporary construction zones may limit access in some areas. The city encourages:
- Using marked crosswalks and pedestrian signals.
- Avoiding construction zones on foot or bike.
- Reporting unsafe conditions to KCMO Public Works.
Frequently Asked Questions About Kansas City’s Road Diet Projects
Q: When will construction begin, and how long will it last?
A: Construction on Southwest Trafficway is expected to start in late May 2026, with projects on 33rd Street and Linwood Boulevard following shortly after. Each project is anticipated to last 6–8 weeks, depending on weather and logistical challenges.
Q: Will there be traffic delays for emergency services?
A: The city has committed to minimizing delays by installing priority signals and designating emergency lanes where feasible. However, some slowdowns may still occur during peak construction hours.
Q: Are there alternate routes I should take?
A: Yes. For Southwest Trafficway, consider using 39th Street or Broadway as detours. For 33rd Street, 29th Street or 37th Street may offer alternative paths. Always check Google Maps for real-time updates.
Q: How can businesses prepare for disruptions?
A: Businesses are encouraged to:
- Coordinate with delivery services to adjust schedules.
- Communicate with customers about potential delays.
- Contact the Kansas City Chamber of Commerce for resources and support.
Q: What are the long-term benefits of these projects?
A: The road diets are expected to:
- Reduce traffic accidents by 20–30% (based on similar projects in other cities).
- Improve air quality by reducing idling and congestion.
- Enhance the livability of neighborhoods by making streets safer for pedestrians and cyclists.
- Support economic growth by improving access to local businesses.
Key Takeaways
- Three major Kansas City roadways—Southwest Trafficway, 33rd Street, and Linwood Boulevard—will undergo lane reductions and traffic-calming measures starting in late May 2026.
- Expect increased travel times, particularly during rush hours, with detours recommended for affected corridors.
- Emergency services and delivery companies are being coordinated with to minimize disruptions, though some delays are likely.
- Pedestrians and cyclists will see improved safety and access with dedicated lanes and crosswalks.

Looking Ahead: What’s Next for Kansas City’s Transportation?
These road diet projects are just the beginning of Kansas City’s efforts to modernize its transportation infrastructure. Future initiatives may include:
- Expansion of bike lanes and pedestrian pathways across the city.
- Investments in public transit and micro-mobility solutions, such as e-scooters and bike-share programs.
- Smart traffic management systems to optimize flow and reduce congestion.
