During my lifetime, I've lived near a great deal of Oregon State Highways. When you live in eastern Marion County, Silverton-Mollalla-Mount Angel-Stayton and the like, State Highways are like the Force (insert lame joke here). They do bind the world together, and since one seems rather distant from an Interstate and even moreso from a US highway (none of those run through Marion or Polk counties), they define existence to a degree (I was born on a bluff overlooking State Highway 213).
One thing that might happen to the native Oregonian and map lover (myself, to be precise) is that one notices the subtle differences in usage and attitudes in the common arena. For instance I noticed, long ago, that surrounding states either called thier signed highways "State Route" (like SR 14 in Washington-I don't hear "Washington Hwy 14" often) or affixed the state name ("Califonia 1"). I also noticed a certain cachet about certain route numbers that migrated into the names of businesses along the route. When I was small, a lot of business along the Coast Highway called themselves "Hwy 101 [this or that]"; an old tavern on Portland Road in Salem just north of the Hazelgreen Rd-Chemawa Rd junction called itself "Flight 99" (even though it was adjacent to the old bed of Lake Labish-no airport in sight); the famous drive-in in Newberg still calls itself the "99w".
I also noticed that there is no signed Oregon State Highway 1.
That was not always the case. The early Oregon highway system not only had a State Highway 1 but also a State Highway 2. Highway 1 was roughly congruent to today's Pacific Highway (99, 99E, 99w) and Highway 2 was, at least in part, the highway west from Portland to Seaside, today's Sunset Highway.
In Oregon, highway numbers have a strange double life. There are two systems of highway numbers in Oregon; the numbers on the signs (what the average Joe Motorist things of as a State Highway number and what ODOT calls a "Route" number) and a so-called "secret" highway number, though I prefer to think of it as an inventory number (kind of like the stock inventory numbers grocery stores use on things they sell). For instance, US 26 and I-84 are still designated Highway 2 in the state inventory. Likewise, signed State Highways 99, 99E, and 99W are inventoried as Highway 1, 1E and 1W respectively.
Latterly, the state is resigning some unsigned state routes to give them state highway signs agreeing with these inventory numbers. For instance, the highway cutoff from the south end of the Boone Bridge in Wilsonville has a new name: State Hwy 551. And not many know this, but the route described by North Marine Drive past the Expo Center and North Portland Road leading to the Fessenden Six Corners in north Portland is a State Hwy: the Swift Hwy (named for the old meat-packing concern), State Hwy 120. When that one will get a shield is anyone's guess.
Anway, my point (and I do have one) is that if we can designate and mark these routes, why not establish the ultimate state highway cachet address: Oregon State Hwy 1.
Highway 1's are cool. Look at US 1, California 1. People remember these routes. It' be very fine indeed to give directions to a place and be fortunate enough to say "I'm just off State Hwy 1".
The only problem I see is choosing which roads to designate. Oregon is a place with great variety. Also changing route numbers is a tricky proposition; people know the current route numbers very well indeed.
I do have a suggestion: Hwy 99E would make a marvelous Hwy 1. We'd still have Hwy 99 (shifted from 99W) which is a cachet designation in itself. South of Junction City it could duplex with Hwy 99 to Eugene, then dance around I-5 through southwestern Oregon. That's just my idea, anyway.
I think it's time we had an Oregon State Hwy 1.
