Missouri Set to Increase Interstate Speed Limits
The Missouri Department of Transportation (MODOT) has announced new changes to speed regulations on several rural interstate highways. As revealed by MODOT Director Ed Hassinger, certain stretches of interstate roads in Missouri will soon feature increased speed limits, aiming to streamline travel for motorists across the state.
Over 150 New Speed Limit Signs to Be Installed
MODOT expects to install more than 150 new speed limit signs before the end of the year. These signs will officially raise the speed limit to 75 MPH on designated sections of several key interstates. The updates are part of an initiative to modernize speed regulations in rural areas while maintaining safety standards for all drivers.
Interstates Impacted by the Speed Limit Increase
The interstates scheduled for the new 75 MPH speed limits include:
- I-29 in northern Missouri (i29 speed limit)
- I-35 also in the northern region (i35 speed limit)
- I-55 in the southeast part of the state (i55 speed limit)
- I-49 in southwest Missouri (i49 speed limit)
Each of these highways passes through mainly rural areas, making them prime candidates for higher speed limits under current transportation and safety assessments.
Additional Advisory Signs to Enhance Safety
In addition to the new interstate speed limits, MODOT crews will place warning and speed advisory signs at specific curves along affected interstates. These advisories will indicate a recommended speed of 70 MPH in areas where roadway conditions may require extra caution. This approach balances increased speed with continued highway safety.
Implementation Timeline
All new signs—both 75 MPH and advisory warning signs—are projected to be installed by the end of 2026. MODOT crews have started preparations to ensure a smooth transition to higher limits, as part of ongoing efforts to support efficient travel on Missouri highways.
Overview of Missouri’s Approach to Speed Limits
This move comes as part of a broader evaluation of modot speed limits on rural interstate highways. By focusing on stretches of highways with well-maintained infrastructure and less congestion, MODOT aims to provide a more consistent driving experience for motorists crossing long distances in Missouri.
Looking Forward
Missouri drivers traveling via I-29, I-35, I-55, and I-49 can anticipate faster travel times on routes where the new missouri speed limits take effect. For those navigating curves on these highways, the addition of speed advisory signs will serve to highlight recommended safe speeds without altering overall travel efficiency.
