From the aerial photo, it looks like two roads (Undercliff Road and
Halesworth Road) come out on Loampit Hill next to each other, with
a 6-8 foot wall between them. I'm not aware of a feature like
this anywhere else...

In Toronto we have a location where two main streets, of 4 and 6 lanes
(Fleet Street and Lakeshore Boulevard) run side by side for about
1000 feet with nothing between them but a sidewalk (footpath) the
width of a traffic lane or less. Both have two-way traffic and Fleet
also has streetcars (trams).

Here's their intersection with Bathurst Street, where Fleet ends:

Bathurst has streetcar tracks in both directions, with a double-track
triangular junction in the intersection. The tracks straight along
Bathurst are not used in regular service; The two routes serving the
area (509 and 511) both run along Fleet, turning opposite ways to/from
Bathurst. On both streets the streetcars share their lanes with road
traffic, but Streetcars are the only vehicles permitted to turn right
from Fleet onto Bathurst or left from Bathurst onto Fleet. Here's a
picture of one of them doing it, although it doesn't clearly show the
layout of the intersection:
