Regional Project Information

Kempton Bridge & NW 66th Avenue Improvements - A Polk County project involving the city of Johnston.

Project Update (8/6/18):
Work on Phase 3 of the NW 66 Ave. Reconstruction project continues. The flash flooding and resulting high water table on the project site has caused some delay in the project schedule, but we are hopeful favorable weather this fall will allow the project to still be completed in December of this year. Stage 4B (see the Project Information sheet on the website for details) will hopefully be completed by September 1st with the temporary detour removed shortly thereafter.

Once the temporary detour is removed- work will begin on Stage 5, which includes reconstruction of the south half of NW 66 Ave. between NW Toni Dr. and NW 26 St. We wish to thank motorists for their cooperation and patience during the recent period of adverse weather conditions.
