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 its 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.
The primary objective will be the development of a master plan for the IA 141 corridor from the north IA 44 interchange to the IA 415 interchange. The plan will include short-term and long-term build-out needs of the corridor including access management, safety performance, major intersection location form and function. The plan will provide the basis for future access management coordination and potential roadway improvement project planning.
A public open house will be held on Wednesday, August 18th, from 5:30-7 p.m. at Johnston City Hall, 6221 Merle Hay Rd, Johnston, IA 50131. During the meeting, no presentation will be given. Rather it will be an open house format to encourage attendees to express their views and opinions and to ask questions regarding the proposed amendments. You may provide any questions or comments regarding this draft plan either orally at the meeting or by submitting written comments to email@example.com.
