A local arterial road used as a connector from a number of Coralville neighborhoods to Northwest Junior High School has been closed pending construction of a new water main.

Coralville’s 20th Avenue will be shut down between Ninth Street and 20th Avenue Place because of the planned installation of a new water main, a Thursday news release said.

Residents who live in the area of construction will be allowed admittance through Ninth Street Place.

All traffic flow has been detoured to 20th Avenue Place.

Due to storm intake replacement and pavement reconstruction, the closure will last for several weeks. Following completion of this project, construction will be take place between 20th Avenue Place and 10th Street.

The 20th Avenue corridor is scheduled to reopen at the end of October, weather permitting.
