The Eau Claire–Chippewa Falls metropolitan area refers loosely to the urbanized area along the Chippewa and Eau Claire Rivers, in west-central Wisconsin, with its primary center at Eau Claire and secondary centers at Chippewa Falls and Altoona. At a ribbon-cutting for the opening of the final stretch of the newly 4-laned section of WIS 29 between Green Bay and Elk Mound, in 2005, Gov. Jim Doyle referred to the region, including Menomonie to the west, as "Wisconsin's Golden Triangle."
