Here's a table of the Washington State Primary Highway System in 1938. This is based on a Rand Mc Nally atlas of that year-a reasonably reliable source, since Rand Mc Nally did the maps issued by the state. Besides the roads shown here, there was also an alphanumeric system for secondary roads.(P- a, b and so on; the highest letter used was "U"). A number of these roads had more than one branch, indicated by a horizontal line or  tablseparatee cells 


Distances shown are distances between main points on the road-according to the 1938 atlas. Distances shown with "*" are approximate and based on the 1997 AAA Atlas. Active US highways are shown in RED -bear in mind that the roads shown as "active" may not follow the 1938 alignment.

Where Are They Now?

The above table is not much use unless it's put into a modern context. Unless you have a 1938 atlas or have a good knowledge of Washington State, you're prolly wondering which road is which. Following is a list of the roads and their modern counterparts.  Significant turns are orange.


NOTE: The following directions are as accurate as possible, given my sources, however, they are very general and approximate(that means if you get lost, don't blame me!!!!). If you want to go prospecting for single slabs, you should have a map(AAA Washington makes some good ones) and a GOOD compass. If you want to go super techie, get a GPS thingie. But then a map and a compass don't have battery faults....

Well, I hope this has all been fun and educational. If there are errors in this bit, please e-mail me. I hope you'll get to actually physically go and look for these roads, besides some old and spiffy concrete, you'll also be treated to some really beautiful scenery.
