From here north to E. Alder Street in Leschi, the lakeside road is named Lakeside Avenue, and Lake Washington Boulevard diverts to a winding route through Colman, Frink, and Leschi Parks.

At E. Denny-Blaine Place, the road heads northwest, through Lakeview Park and the grounds of The Bush School, to the south entrance of the Arboretum at E. Madison Street.

The boulevard ends at the Montlake overpass of 520, where E. Montlake Place E. becomes Montlake Boulevard E. The road is popular among cyclists—indeed, it was originally conceived as a bicycle path before automobiles had become widespread[2]—and is closed to auto-traffic ten days out of the year for recreation.

[3] The road was listed on the National Register of Historic Places in 2017.

[4] The cities of Newcastle, Bellevue and Kirkland on the Eastside, as well as the city of Renton, also have roads along the lakefront with the same name; the Eastside road was once continuous and paved in 1932.
