Man, i wish i had the foresight to take pictures of US 26 eastbound a couple miles before the Vista Ridge tunnel when i was still very young. Not only were the BGSs unusual in the fact that the reassurance shields were posted above the signs, but all the route shields for I-405 and US 26 were cutouts with the state names! Well, the first gantry after the zoo exit had the classic US 26 with state name, but the next four gantries used California style US shields. Even the gantries after the tunnel before merging onto I-405 or exiting to downtown were set up in such a way. The new signs that replaced these several years ago still have the reassurance shields posted over the BGS itself, but now feature the square back US shield and non-state name Interstate shields. If there were any roadgeeks in Portland whom have snapped pictures of the gantries before they got updated (prior to the late 90's), i'd love to have copies!
