Highway 141 Traffic Study Public Meeting

Thursday, May 13, 2021

The Cities of Grimes & Johnston, and Polk County are partnering with the Iowa DOT to prepare a traffic access management and operations review of the IA 141 corridor between the IA 44 (E 1st St/NW 70th St) and IA 415 interchanges. A map of the approximate three-mile-long IA 141 study corridor specific to this effort is shown in the accompanying exhibit. Each City has completed recent updates to their Comprehensive Land Use plans for the areas of influence on the corridor. The study will incorporate the Johnston Thrive 2040 Comprehensive Plan Update, the 2018 City of Grimes Comprehensive Plan, and the Polk County / Iowa DOT IA 141/415 Corridor Study (121st Street intersection improvements to the north). These plans along with continued traffic growth, crash history, and land use development have demonstrated the need for the agencies to evaluate short and long term needs for continued safety and efficiency of operation for the future.
