Starting Monday, the Iowa DOT will move sanitary sewer repair work north to the 5th Avenue intersection, closing the intersection to 5th Avenue traffic from the east. The current closure at 3rd Avenue will be reopened to traffic when the 5th Avenue closure begins.
The repair at 5th Avenue will be the last sanitary manhole repair in the center lanes of Highway 146. Once this is complete, construction will shift to outside lane closures for water main work, storm intake replacements, sidewalk improvements, and street light installation..
Thank you for your patience as this project continues. Please use caution in the work zone and follow posted traffic control signs.
