 The area remains an affordable area close to the high employment areas of Renton and Seattle.The name "Skyway" may be derived from the area's siting on a high ridge in western Washington's hilly terrain, a name that echoes the Welsh "Bryn Mawr" (also the name used for a village and several other places), which means "big hill".Skyway's main business districts lie along Renton Avenue South, with one center between 68th Avenue South and 74th Avenue South, including a small casino, bowling alley, and a grocery outlet, and another district between 75th Avenue South and 78th Avenue South, including a bank branch, the fire station, multiple churches, a 7-11, some auto shops, and the public library (a branch of the King County Library System).
