(KAIR)--A major Atchison traffic route is set to close Thursday.

That word is delivered in a release from the City of Atchison, which says the 14th Street Viaduct will be closed for the entire day, and possibly part of Friday.

The reason for the work is ongoing fiber line installations.

According to the City, the viaduct will remain open for the Thursday morning commute, closing at 8:30, "to minimize impacts to school/work commutes."

The 14th Street Viaduct will remain closed until the work is complete, expected by late Thursday or early Friday morning.
