Blue River (Missouri River tributary)
The Blue River (also known as the Big Blue River) is a 39.8-mile-long (64.1 km)[3] stream that flows through Johnson County, Kansas, and Jackson County, Missouri, in the Kansas City Metropolitan Area.Along the Blue River can be found many miles of hiking, biking, and walking trails.The route was straightened in 1954 with the use of three high trestle bridges over the Blue River and one substantial cut.This improved line is now the Union Pacific - Kansas City Southern Mainline and generally parallels the Blue river into the bottoms railyard near Front Street in Kansas City.During the Civil War, the Blue River was the site of the Battle of Byram's Ford.
