North 17th Street Bridge Replacement Project
Project Name
North 17th Street Bridge Replacement Project

General Area
NE Quadrant


Project Description
  • The scope of this project includes the construction of a new bridge over a branch of Spring Creek and the re-alignment and replacement of the roadway approaches to that bridge.  
  • In addition, the Mahaska Community Recreation Trail will be incorporated into the new bridge as a shared use path.

Project Benefits
The existing bridge on North 17th Street was built in 1936 and is in need of replacement.  When it was inspected in 2015, it was given an estimated remaining life of 2 years, which means that failure of the bridge is imminent.  In addition, the existing bridge height is not adequate for flood events and may not withstand significant rainfall events.  Currently, this bridge provides access to the Northeast Wastewater Treatment Plant and the Stephen Memorial Animal Shelter.  This project will allow for the construction of a new bridge meeting the current flood height requirements.  In addition, the Mahaska Community Recreation Trail will be incorporated into the new bridge as a shared use path.
  
Project Location
  • North 17th Street north of Carbonado Road and southeast of the Wastewater Treatment Plant.
