==Extra Highways== 

 Does anybody know what the deal is with these extra highways?  I haven't been able to find if they are/were state highways or merely county highways: 

 Shaw Highway, Marion County 
 St. Paul Highway, Marion County 
 Mt. Angel Highway, Marion County (old Hill-Sil?) 
 Wilco Highway, Marion County (seems to be the portion of Hill-Sil from Woodburn to Mt. Angel) 
 Delta Highway, Lane County 
 Lorane Highway, Lane County (seems to share some routing with old Fox Hollow Highway and Terrtorial Highway) 
 Brownsboro Highway, Jackson County (based on old maps this is an old alignment of Lake of the Woods from Brownsboro to Eagle Point, but no idea whether it was retired to the county or retained by the state.) 
 Butte Falls Highway, Jackson County (AKA Butte Falls-Prospect Rd between those two towns.  Possibly an initial routing of Crater Lake Highway?  Same conundrum as Brownsboro Hwy)
