FARGO, N.D. (AP) — Voters in Fargo and Cass County have approved extending sales taxes to help pay for a $2.2 billion Red River diversion channel around the Fargo-Moorhead area.

Unofficial returns from Tuesday’s election show the measures got 63 percent approval in the county and 66 percent approval in the city.

Fargo originally passed taxes for flood protection in 2009 and 2012. Cass County first approved a tax in 2010. The taxes will now extend through 2084.

The 30-mile long diversion channel is estimated to be completed by the year 2024, but construction hasn’t started yet.
