Secondary Roads

Weather permitting, closure on West Penn Street is expected to begin the week of April 15. Penn Street will be closed to all traffic during phase two of West Penn Street just east of the James Avenue intersection to Herky Drive. Travelers should use the posted detour route. Phase one of the Penn Street/James intersection is slated to begin in late summer 2024. This is a joint project between the City of North Liberty and Johnson County.  

Construction is expected to be substantially complete by the end of August 2024. Peterson Contractors, Inc. of Reinbeck, Iowa is the prime contractor and can be reached at 319-345-2713. 

Please slow down and drive defensively within the project corridor. Your patience and understanding are greatly appreciated while we work to complete these improvements as quickly as possible.
