Unable to answer "What’s the height limit below the bridge?" – Service Road – way/1171263167 via StreetComplete 61.1:

Not a bridge?

Regarding expressway=yes for Milwaukie Expressway: according to OSM wiki, undivided highway without full access control shouldn't be tagged as expressway=yes. What do we think?

missing mountain biking and hiking trails in Thurston Hills NA. See e.g. https://www.trailforks.com/region/thurston-hills-natural-area-24154/ and https://cms2.revize.com/revize/willamalanepror/Documents/Parks%20&%20Trails/Park%20Maps/THNA%20Winter%20Closures_rev.pdf

Can we clarify the basis of giving the Oregon portion a Washington state route ref? I did a little digging and found conflicting evidence.

Evidence/argument for:
TIGER Lines assign the Oregon portion, between state line and the first intersection with US 30 ramps, as WA 433;
new ODOT overhead signage on EB US 30 signs the exit as "WA 433" instead of "To WA 433"

Evidence/argument against:
WSDOT GIS has WA 433 ending at state line;
ODOT GIS shows the Oregon portion as ODOT-owned and maintained, not part of signed routes, and as a connection rather than a highway route;
having a WA state route in OR is very unusual and I'm not aware of similar cases

Calling all Vancouver editors:

WSDOT has opened a new ped/bike bridge and sidewalk/crossing improvements here. Actual pictures and imagery are hard to find, so if anyone in the area wouldn't mind going for a walk/bike ride...

Interchange from NB WA-7 to NB I-5

Road opens May 30th

this section of Powell (13th Pl - 12th Ave, maybe up to Milwaukie) should be mapped as two-way highways to account for the central turn lane
