Frequently asked questions

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 to its west and Bellevue to its east.

The island is connected to the mainland on both sides by bridges carrying Interstate 90, with the city of Seattle to the west and the city of Bellevue to the east. 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. 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 King County's Eastside.

The population was 25,748 at the 2020 census. Mercer Island has the fifth highest per-capita income in the state of Washington and is one of the 100 richest ZIP codes in the US according to the IRS figures for Adjusted Gross Income.

The western side of the island was home to two Snoqualmie villages before white settlement in the Puget Sound region. Mercer Island, named for the Mercer family of Seattle, was first settled by non-indigenous people between 1870 and 1880. The Mercer brothers often rowed between the island and Seattle to pick berries, hunt, and fish. Those brothers, Thomas Mercer and Asa Mercer, were members of the Mercer family of Virginia. The first large settlement, East Seattle, was toward the northwest side of the island—near the McGilvara neighborhood. In 1889, C.C. Calkins built a large and gilded resort, the Calkins Hotel. The hotel was reached via steamboat between Madison Park, Leschi Park, and the Eastside. Guests included President Benjamin Harrison, of 1901, amongst other well-to-do dignitaries from Seattle to the East Coast of the United States. Burned by a mysterious fire, the hotel was razed in 1908.

The City of Mercer Island was incorporated from East Seattle on July 5, 1960, and comprised all of the island minus the 70-acre (280,000 m²) business district. Just over one month later, on August 9, the Town of Mercer Island was incorporated from that business district. The two aforementioned municipalities merged as the City of Mercer Island on May 19, 1970.
