The City of Parkville is pleased to announce that a traffic study at the intersections of Crooked Road, River Hills Drive, and S. National Drive has been completed. The intersections serve the River Hills and Cider Mill Ridge subdivisions. The study, produced by TranSystems Corporation, makes recommendations to address operational and safety conditions at the two adjacent intersections. A public meeting has been scheduled for June 24 to present the results of the traffic study and to discuss other traffic related issues in the area.
In 2013, at the request of residents in the River Hills subdivision, the intersection was studied and at that time it was determined that a four-way stop was not warranted. The Board of Aldermen made a commitment that it would conduct a new study when the newer subdivisions started to build out and traffic volumes increased.
In 2018, when the last Plat of Cider Mill Ridge was approved and its construction began, the Board of Aldermen approved a new traffic study funded by a Transportation Engineering Assistance Program grant from the Missouri Department of Transportation.

In addition to determining the warranted traffic control devices at Crooked Road, residents and City staff were concerned about limited site distance and increased traffic volumes on S. National Drive due to the new homes being built in the 7th Plat of Cider Mill Ridge. City staff installed interim yield signs on the minor legs of S. National Drive to address resident safety concerns. The traffic study commenced and reviewed operational and safety conditions at both intersections and provided recommendations to address any existing deficiencies.
The study determined that a four-way stop at Crooked Road and River Hills Drive was not warranted and should continue to operate with stop signs on the north and south legs of River Hill Drive. The study further determined that the north River Hills Drive intersection with S. National Drive be modified to remove the existing yield signs and install a single northbound stop sign on River Hills Drive.
Mayor Nan Johnston said, “The traffic study makes recommendations that will help improve traffic flow at the intersection and improve vehicle and pedestrian safety. It is the City’s goal to provide citizens with safe access to all areas of the city.”
To hear the results of the study and to discuss other traffic related issues, the Board of Aldermen will have a work session on Monday, June 24, 2019, at 6:00 p.m. at Parkville City Hall, 8880 Clark Avenue. The public is invited to attend.
