Gravel Switch is an area along the Paducah & Louisville Railway (PAL) between the Kentucky Dam on the Tennessee River and Grand Rivers in Livingston County, Kentucky, United States near the interchange of U.S. Route 62 and Kentucky Route 453.

[3] It remains a rail, barge, and transloading terminal for aggregates for Vulcan Materials Company's Grand Rivers Quarry.

[4][5][6] In the early 1900s PAL's predecessor, the Illinois Central Railroad, had a spur line (its Kentucky Division[7]) to this locale where rock was harvested for use as track ballast for the laying of track.

[9] After the Kentucky Dam was built and the Tennessee River basin filled (1955 maps), half of the Gravel Switch area and part of the rail line was submerged.

The rail line was re-routed over the dam[10] and through the Gravel Switch spur area, which was left above water level,[9] the elevation difference about 36 feet (11 m).
