This street runs ¼ mile from 1st Avenue S in the west to 4th Avenue S in the east. West of 1st, it’s S Atlantic Street — its original name — and east of 4th, it’s the beginning of Interstate 90. It is part of State Route 519, a short highway that connects I-90 to Washington State Ferries’ Colman Dock.
Now — why is it Edgar Martinez Drive S instead of S Edgar Martinez Drive, since east–west streets in Seattle have their directional designators at the beginning? I asked Paul Jackson this in 2005. Jackson, who was then the Seattle Department of Transportation’s manager of traffic, signs, and markings, responded:
I appreciate your desire to see our City’s sign system remain consistent.… But ultimately, there is nothing requiring such a naming convention in the Seattle Municipal Code.… In this case, those proposing the street name change wanted to see Edgar Martínez’s name out front. Because this is only a three-block stretch of street (from 1st Avenue S to 4th Avenue S), and does not have any addresses along it, the decision was made to veer slightly from the typical naming convention. The term “drive” was agreed upon to evoke Mr. Martínez’s batting skills at the plate.
