Eastlake Avenue E

Like NE Northlake Way, Eastlake Avenue E is so named because it runs along the shore of Lake Union — in this case, obviously, the eastern one. It, too, was earlier named Lake Avenue (in part), but this was changed as part of the Great Renaming of 1895. Ordinance 4044, Section 6 reads

That the names of Albert Street, Waterton Street, Lake Avenue and Green Street from Depot Street [changed by the same ordinance to Denny Way] to the shore of Lake Union at the northerly point of the Denny–Fuhrman addition, be and the same are hereby changed to Eastlake Avenue.

Today, Eastlake, at 2⁹⁄₁₀ miles in length, extends slightly farther north and south than the roadway mentioned in the ordinance. It starts in the south at the intersection of Court Place and Howell Street as Eastlake Avenue, then becomes Eastlake Avenue E a block north as it crosses Denny Way. From here to just south of E Galer Street it divides the Avenue: E; Street: E section of town from the Avenue: N; Street section. Just north of Portage Bay Place E it crosses Lake Union as the University Bridge, then continues on as the one-way–northbound Eastlake Avenue NE to 11th Avenue NE just north of NE 41st Street. (Southbound, it is fed by Roosevelt Way NE at NE Campus Parkway.)

Eastlake, like Fairview and Boren Avenues, is one of the few north–south streets in Seattle to have three different directional designations.

Portage Bay Place E

This street, which runs ³⁄₁₀ of a mile from Fuhrman Avenue E to E Allison Street, was established as an alley in 1890 as part of the Denny–Fuhrman Addition to the City of Seattle, but only received a name in 1936. It was named for Portage Bay, the eastern arm of Lake Union, which it parallels. Portage Bay was in turn named for the portage from Union Bay (part of Lake Washington) to Lake Union over the Montlake Isthmus, which is today the Montlake Cut of the Lake Washington Ship Canal.
