Middle Bridge is the crossing of Blue Mesa Reservoir (the Gunnison River) on U.S. Route 50 (US 50) within the Curecanti National Recreation Area in southwest Gunnison County, Colorado, United States, about east-northeast of the community of Sapinero. Prior to the construction of the Blue Mesa Dam, US 50 did not cross the Gunnison River there, and a portion of the old highway can be seen descending into the lake.
