Oregon City to 21st and Columbia Blvd

[OldHouseMan]

My wife and I have been looking at houses in Oregon City, right above down town, and there's no way I'm driving that commute to work.

Here's the general route I'm thinking of...

River Rd
to
Sellwood
to
Possibly onto the Springwater trail
or
Through town on surface streets
to
15th (already ride 15th to work)
then
onto work

Something like 18-20 miles

Obviously there are a few connectors that need to be made that I did not list, but what I'd like to know, is there a bike friendly route from Oregon City to the Clackamas Towncenter Max Station? Or even the 205 bike path? I do not mind fighting traffic occasionally, but don't want to do it day in and day out.
