E Interlaken Boulevard

The establishment of E Interlaken Boulevard — the first of Seattle’s Olmsted parks and boulevards we’re covering — was first proposed, according to Seattle parks historian Don Sherwood, in 1903 as Volunteer Hill Parkway. Two years later, the current name was adopted. There is speculation, but no documentation, that it was named for the Swiss resort town of that name. Ask a Seattleite how to pronounce “Interlaken” and you may hear either lake or lock, the latter being more common according to an informal Twitter poll I ran (but the former being the one I grew up with).

Text of a Twitter poll by me, reading "Seattleites! How do you pronounce “Interlaken,” as in Interlaken Drive, Interlaken Boulevard, Interlaken Place, and Interlaken Park?" LOCKen 55.8%, LAYKen 34.7%, something else (comment) 2.7%, results only 6.8%. 147 votes total

Note: On July 10, 2024, I began converting embedded tweets on this website to screenshots because of issues with how they were integrating with WordPress, which began not too long after Elon Musk purchased Twitter and changed its name to X. Here is a screen shot of folks’ comments.

Interlaken Boulevard runs for about 1⅔ miles west to east from Delmar Drive E, by Seattle Preparatory School on Capitol Hill, to Lake Washington Boulevard E, in the Washington Park Arboretum. The middle section, between 19th and 21st Avenues E, is closed to motor vehicles and functions as a pedestrian and bicycle trail. The name also appears on Interlaken Drive E and Interlaken Place E — and should not be confused with Interlake Avenue N, a street in North Seattle.
