Recreation

Along the Blue River can be found many miles of hiking, biking, and walking trails. Portions of these trails trace the path of a former steam railroad track of the Missouri Pacific Railroad line that ran from Dodson, Missouri south to Martin City, Missouri. This rail bed followed the Blue River and had many curves. 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 / KC Southern Mainline and generally parallels the Blue river into the bottoms railyard near Front Street in Kansas City.

History

On the high bluffs overlooking the confluence of the Blue River and the Missouri River can be found a large Native American mound structure, designated as Indian Mound Park in the Indian Mound neighborhood of Kansas City, Missouri.

The three western trails, the Santa Fe, Oregon, and California trails crossed the river just north of Red Bridge Road and Minor Park. Mountain man/ fur trapper Jim Bridger had a trading post at this location.

During the Civil War, the Blue River was the site of the Battle of Byram's Ford.
