Via http://www.lukestubbs.com/index.php/78-blog/83-portsmouth-s-1970s-roads-plan comes this short article showing off the road plans for Portsmouth in the 1970s discovered while searching for references to famous Pompey landmark, the Johnson & Johnson Roundabout (not a roundabout; no Johnson & Johnson building; but those of us of a certain age know where it is). For me, at least, it’s quite weird to see what might have been, especially the route the Eastern Road would have taken all the way into the city centre.
The northern part of the Eastern Road was to be upgraded to full dual carriageway with flyovers. The southern part was to follow a completely different line that would have linked up with Winston Churchill Avenue. Departing from the old road just south of Portsmouth College, it would have hugged the coast, crossing open space that is now the University’s Langstone campus before turning in and following a line along the old canal just off Locksway Road. [...] The road would then have continued broadly along the line of Goldsmith Avenue. It is because of the safeguarding of this route that some of the industrial units around Fratton station remain to this day.
Clicking the image below will load a very high resolution image of the plan (over 7MB in size; you have been warned) or you can head along to Luke’s site via the link above to see a few close crops of areas of interest as well as some write-ups of the seventies’ proposed road plans for Portsmouth.
