Discussion:
After completion of the McKenna Road reconstruction near Eagle Creek Boulevard, a speed limit was not established for McKenna Road between Eagle Creek Boulevard and Tintaocanku. Prior to the reconstruction of McKenna Road and the construction of the roundabout, the speed limit was posted at 55 mph, which is the statutory speed limit for this section of roadway. With an existing speed limit of 30 mph on McKenna Road south of Tintaocanku, the Traffic Safety Committee determined that an appropriate speed limit should be determined for this section of road.
The process of having a speed study conducted involves adopting a resolution requesting a speed zone investigation by MnDOT. In order to proceed with a speed zone study, the City Council must adopt a resolution requesting the Commissioner of Transportation to conduct a speed zone investigation.
A MnDOT speed study involves collecting vehicular speeds and reviewing the roadway geometrics and other roadway factors. Using the data that is collected during the study, a speed limit will be set by MnDOT and frequently is based on the 85th percentile speed. Once determined, the city would then install the appropriate speed limit signs.
