US 99 prior to the Aurora Bridge

[Max Rockatansky]

Does anyone have any solid map data on where the hell US 99 was north of downtown Seattle prior to the Aurora Bridge opening in 1932?  The AASHTO database didn't have any information in filed for Washington State and topographical maps jump from 1909 to 1949.

The only solid map I've ever found is a 1931 edition from Richfield Oil Company.  Said map shows US 99 following Eastlake Avenue towards the University of Washington and Bothell Way towards Bothell.  That seems to make sense based off previous research I did for the Everett and Marysville areas but I was hoping for a better data set.

WSDOT has the 1931 official state highway map online which shows US 99 close to its current routing. This could be referring to the Fremont Bridge, which is close to the Aurora Bridge, but completed earlier in 1917.

That looks like it followed Westlake, the Fremont Bridge, and 15th Ave. NW.

Interestingly the 1925 Rand McNally edition has Pacific Highway on the UW/Bothell alignment and PSH 1 on Fremont Bridge alignment:

The full story can be found on the bridge's Wikipedia page. It should come as no surprise that it opened on George Washington's 200th birthday, given that his name is also that of the state.

Not really, the Wikipedia page is kind of vague about where US 99 was and sort of insinuates the Fremont Bridge.  We're all coming up with contradictory information, it could have been the Fremont Bridge but there isn't enough to say that was original alignment just yet.

This section on the State Route 99 article is more clear. The Fremont Bridge was likely the actual routing given it was historically the shortest path from what is now Shoreline to Seattle, whether by automobile or interurban/streetcar.

Got a scan of citation 45 by chance?  Is that an article which references US 99 being on the Fremont Bridge or just PSH 1?
