Oregon Roads - US 730
All photos are eastbound on the highest numbered US highway left in circulation. Only its brother US 830 was higher.
This is how Oregon signs a highway that gains a striped median. Since stripes aren't a hazard, the sign is unnecessary.
Original "guiderail" marks the 1917 Columbia River Highway, which started out as US 30 in Portland until the Columbia River turns north into Washington. Since that deviates from 30's east-west orientation, US 730 was born to fill in the gap to US 12. This history explains why a 42-mile highway - total, including Washington mileage - can have a Mile 203. That's the mileage of the named highway, which is how Oregon does things.
