Lake Washington Boulevard is a scenic, approximately , route through
Seattle,
Washington, that hugs
Lake Washington for much of the drive. There are views of the lake, small sections of rainforest, meadows, and views of the
Cascade mountains. At its northern end, Lake Washington Boulevard runs through the length of the
Washington Park Arboretum. The road begins at S. Juneau Street in
Seward Park, running thence along the lake to
Colman Park, just south of
Interstate 90. 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. Alder, the boulevard once again runs along the lake through
Madrona Park to just north of
Madrona Drive, where private residences occupy the shore. 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. It continues through the Arboretum to an interchange with
State Route 520. Just north of E. Roanoke Street, the boulevard turns due west and changes from Lake Washington Boulevard E. to E. Lake Washington Boulevard, following the
city's street name designation system. The boulevard ends at the
Montlake overpass of 520, where E. Montlake Place E. becomes Montlake Boulevard E.
