PLATTE COUNTY, Mo. — The Missouri Department of Transportation will be working in Platte County next week. Drivers should expect crews to close North Platte Purchase Drive, between 88th Street and Northwest Tiffany Springs Road, as well as the Missouri Route 152 ramps to North Platte Purchase Drive, starting Tuesday, September 7, and lasting through Sunday, May 18, 2022 for road construction work. Some ramps will need to be closed through November 22, 2022. This is all part of a project to install a new DDI, or Diverging Diamond Interchange, to provide safer traffic flow in Platte County. All work is weather-permitting.
