The following I sent to RallyChris, PDX neighbor AM, and he provided his insight but also agreed that getting outside opinion would be good too.
Give me your thoughts on the start of I-405 N.ODOT says I-405 (Stadium Freeway Hwy 61) starts hereHere is the starting point in PapyrusHere's how it looks in GMaps
My dilemma comes from the fact that the start of I-405 N here is also Exit 299B. Is it appropriate to have a Freeway road type named "Exit ..."? And I am not sure how the road type affects the routing instructions, if at all.
Part 2: The next split in the road is for Exit 1A headed downtown whereas I-405 heads to the right and then sweeps around north into town. The signage above the Exit 1A for Naito Pkwy etc is fine, but the signage for the more ramp-like I-405
is "I-405 / Hwy 26 W/ City Center / Beaverton". Should that segment be named just "I- 405" or should that segment be named as if it were an exit and how the signage reads?
I'm trying to straddle the naming standards, but also what does a driver unfamiliar with the roads need to know to make comfortable turns.
