98040 MERCER ISLAND WA
Mercer Island is a city in King County, Washington, United States located on an island of the same name in the southern portion of Lake Washington. Mercer Island is in the Seattle Metropolitan Area, with Seattle located to its west and Bellevue located to its east.
Mercer Island is connected to the mainland on either side via bridges carrying Interstate 90. The Lacey V. Murrow Memorial Bridge and the parallel Homer M. Hadley Memorial Bridge are floating bridges that span Lake Washington and carry, respectively, eastbound and westbound lanes of Interstate 90 and connect Mercer Island to the northern portion of Seattle’s South End (more specifically, I-90 has Leschi to the north and Mount Baker to the south). I-90 traverses the northern portion of Mercer Island and is then carried from the island to Bellevue over the East Channel of Lake Washington by the East Channel Bridge. Mercer Island is located closer to Bellevue than it is to Seattle, and is therefore often considered to be part of the King County’s Eastside.
