Does anyone have an example of a stretch of road that has two simultaneous wrong-way concurrencies, such that the road has all four cardinal directions signed on it at the same time? Has this ever happened, either in the United States or elsewhere?
My guess is no, this situation doesn't exist anywhere, but I was curious. I've been looking around for an example and have found plenty of places where the road has three directions signed at once, but never all four.
I've heard it happened decades ago in Long Beach CA, though I don't recall details or which four highways were involved (I think US 6 and CA 1 were two of the four).
Before the '64 renumbering, PCH in Long Beach, for a while, featured "North US 91", "South Alternate US 101", and "East SSR 18" shields east of Atlantic Ave. (itself SSR 15 before 1958) and "North Alternate US 101" and "US 6" (unbannered) to the west of Atlantic Ave. Curiously, the Division of Highways kept most of US 6 unbannered within the state (it certainly was that way through my hometown of Glendale), probably because while the route was nationally an east-west route, it was definitely north-south within the state. Occasionally D7 would post a "north" or "south" banner above the shield, most often along the Harbor Freeway as it was extended south from 1954 to 1961, co-signed with SSR 11; these didn't last long, since the US 6 shields were removed at the beginning of 1964. On the multiplex with US 99, the shields were more often than not arranged vertically, with US 99 on the top and US 6 on the bottom with an occasional "NORTH" or "SOUTH" banner above the US 99 shield. In my hometown, much of the length of the pre-freeway route on San Fernando Road was shared with SSR 134; here the shield arrangement was a US 99 and US 6 shield side-by-side on the top and a SSR 134 shield centered below; if memory serves me correctly, there were no directional banners applied to that combination in either direction. The "99" on top of "6" arrangement with a single directional banner above the US 99 shield was carried over to the first section of the Golden State Freeway opened in 1957 (a section built pre-Interstate funding; it didn't get I-5 shields until the adjoining section south to the Pasadena Freeway was opened in early 1961).
But getting back to the OP premise: the "four routes" in Long Beach that were mentioned were likely a combination of the four (five, counting SSR 15 on Atlantic Ave.) that converged on that intersection; no more than three were on any single stretch of street at any time -- and SSR 18 was itself eventually cut back to the corner of Carson St. (E-W, US 91/SSR 18) and Lakewood Blvd.: N-S, SSR 19, with US 91 and SSR 18 multiplexing south over it to the traffic circle at PCH, where SSR 19 terminated and, for a time, US 91 and SSR 18 turned west with north Alternate US 101. When the Long Beach Freeway was completed in 1958 and SSR 15 moved over to its alignment, the co-termini of US 6 and US 91 was moved to its interchange with PCH/Alternate US 101 (also the southern terminus of SSR 15; the freeway was unsigned south of there). At that time SSR 18 was truncated as previously cited; its multiplex with US 91 was cut back all the way to San Bernardino by 1962.
