Isn't SR 20 the north end? Either way, I'm also wondering why it's north–east and not west–east. Did the DOT sign it like that?
Huge blunder on my part. Fixed.
Route description
Located is used twice in the first sentence. You ought to change one of these.
"The highway travel east" Self-explanatory
History
"ending at U.S. Route 99.[15][16] US 99" US 99 needs to be used in parentheses before being used in the following sentence as an abbreviation.
"SR 20 was extended west to Whidbey Island and the Olympic Peninsula over SR 536 and SR 525 in 1973, shortening the highway" Which highway? I know you mean SR 536, but you mention three highways before the comma, so you should specify.
I'll pass the article, but I forgot once again to mention that there is no info regarding pavement other than the repaving in 2009. Great work! –
