Project Summary
The purpose of this project is to improve safety and operations along the Route 67 corridor, a four-lane divided highway, from the Missouri River to just north of St. Charles Street in Street Charles County. Based on the existing intersections design, traffic volumes and motorists frequently speeding along the corridor, serious crash risks are possible as motorists cross the intersections.
Why is this Project Needed?
From 2017-2022, there were 227 reported crashes in the study area, including 7 fatal injury and 11 serious injury crashes.
- Approximately 65% of the crashes were associated with intersections.
- Right angle, turning, and rear-end crashes are the most common at Route 94/Richard Drive.
- Right angle and turning crashes are the most common at Red School Road.
- Several wrong way crashes were also noted along the corridor.
Based on a recent speed study, prevailing speeds are 12-15 mph above the 55 mph posted speed limit.
A Road Safety Assessment (RSA) was conducted in December 2022. The RSA was performed by a multidisciplinary team, independent of the project, to review existing crash trends and identify potential safety issues, as well as opportunities for improvements considering all roadway users. The safety strategies evaluated during the RSA included improvements to the existing signalized intersection, roundabouts, median restrictions, offset left turns and J-Turns.
Project Milestones
The RSA process consisted of data collection, data analysis, and a field review. Data collection and data analyses included speed data, traffic volumes including turn movement counts, crash history, and input from agency stakeholders. The field review included intersection-by-intersection detailed review of existing conditions, traffic and crash data, observations, and potential opportunities for safety improvements.

What are the existing trends along the corridor?
In the six-year period from 2017-2022:
- There were 227 reported crashes in the study area including seven fatal injury crashes and 11 serious injury accidents.
- Right angle, rear-end, and turning crashes are common at Route 94/Richard Drive.
- Right angle and turning crashes are common at Red School Road.
- Several wrong way crashes occurred.
Based on a recent speed study, prevailing speeds are 12-15 mph above the 55-mph posted speed limit.
What strategies to reduce crashes were identified in the RSA?
The RSA team identified several potential crash reduction strategies including the following:
- Geometric improvements such as adding or expanding deceleration and acceleration lanes, and flattening the southbound Route 67 curve north of Route 94
- Intersection improvements such as improvements to the existing signalized intersections, roundabouts, median restrictions, offset left turns, and J-Turns
- Corridor improvements such as improved signing, lighting, guardrail, guard cable, and slope modification
Input from public meetings #1 and #2 was also used to validate problem identification and gather additional data and viewpoints to be considered in the development and selection of future improvements for the Route 67 corridor.
What is the next step in project development?
MoDOT has developed proposed design improvements along Route 67 which will be presented during its March 6 public meeting.
What is the anticipated project cost?
The cost of the project is $19 million.
Is MoDOT purchasing property from landowners?
MoDOT is still evaluating whether any right of way will be needed to make improvements along the Route 67 corridor.
