It is difficult to relate all of John Rocque's routes to modern roads, except in a general way. But the track that will give rise to Bellevue Road is clearly shown wandering north-eastward across the Common from Burntwood Lane (named, left) towards the future Nightingale Lane (not named, right).
Is Rocque faithfully representing what he mapped, within the limits of the techniques available to him and the need to get the job done fast? Or is it largely impressionistic?
The ur-Bellevue is not shown at all on the Corris maps of Wandsworth and Battersea in 1787 - the track must have been insignificant at this time. However, the (approximate) route of the future St James's Drive is indicated by parallel dotted lines.
Notice, incidentally, Earl Spencer's encroachments (outlined in red) along the future Bolingbroke Grove.
See also the "Ghost Road" crossing and re-crossing the parish boundary - it is not the future Trinity Road. The parish boundary and the "ghost road" would have emerged more or less exactly half way between the future Wiseton and Althorp Roads [today's building numbers 22 and 23? [23 and 24? Check].
[Later [date?], the parish and parliamentary etc boundary were shifted 20 yards or so slightly to run down the middle of Wiseton Road - see the 1950s map below - hence the former dead-straight parish boundary now has a little dog-leg in it.]

Looking across the Common you might be able to see in perfect alignment the remaining parish boundary posts on the Avenue and on the corner behind the backs of the houses on Routh and Baskerville Roads.
The approximate route of the future Bellevue Road is indicated by parallel dotted lines on Milne 1800, though still as a simple rough track.
Notice also the northbound track that will become St James's Drive heading towards the bottom of Nightingale Lane as soon as the fields (bottom right) are cleared. (These are fields in Streatham Parish that Earl Spencer did not own - the field edges here relate to today's Boundaries Road.
Actually, not quite the course of St James's Drive - which will be built slightly to the west of this old track, probably to reach Five Houses Lane (Bolingbroke Grove) more directly. Notice also that the future Bellevue and St James's do not cross - they meet at the foot of Nightingale.

The course of the future Bellevue and St James's is here represented rather differently from Milne. Travelling north-westward from Tooting, the track follows the parish boundary between Wandsworth and Battersea [hence may be part of what I've called the "Ghost Road" along the parish boundary travelling between Tooting and Battersea, or is it?] until it meets the future Bellevue, then veers slightly towards the Five Houses Road (the future Bolingbroke Grove). Very interesting.
I have digitally combined the tithe maps for Battersea and Wandsworth. They do not meet exactly - indeed, although the route of Bellevue Rd is shown in Battersea, there is only a short suggestion of its future route on the Wandsworth side, and it does not connect with the top of Burntwood Lane [CHECK original maps]. Earl Spencer had built both Bellevue and St James's in the 1820s, so they are clearly shown [CHECK original maps].
Of course the railway line would not be in existence for another 20 years or more. Hence notice St James's crosses Bellevue and continues a few hundred yards over the Common before turning slightly to join the future Bolingbroke Grove.
The (as yet unnamed?) Bellevue Road is flanked on its southern side by a row of trees marking the boundary of McKellar's Triangle - but there are no houses. A railway interrupts St James's Road/Drive, but Bellevue itself is carried over the track by a bridge. At this point, there is no railway station. The area to the south ("McKellar's Triangle") appears to be a large undivided triangular field. ].
Once the railway appeared, both roads were interrupted - the roads no longer crossed but met and a bridge had to be constructed over the line. However, you can still see the course of St James's to the north of the crossing pint [where the Hope was built c.1865] - represented today by a short section of path on the Common (which then turns slightly to run along the railway line to today's lake - there was no lake here until the 1860s and later). For a while, this stub of the old road provided an access route for carts collecting gravel.
[The ?20-acre field formed by Bellevue, St James's Road/Drive Wandsworth & Tooting Lane (Trinity Rd) is often called McKellar's Triangle. McKellar had lived at Wandsworth Lodge, at the southernmost end of St James's Road, and acquired the land ... from Earl Spencer in [date?] ....He used it for agriculture but on his death...things changed very quickly...[FINISH].]
[The view over the Common was still mainly of furze bushes. But what a difference a decade has made to McKellar's Triangle. There are now roads crossing it, and of course numerous houses.]
[The view over the Common was mainly of furze bushes.
Most of the shops and houses that we still see today have been constructed (or at least their descendants on the same plots), and (most of the) building numbers have been firmly established.
Where exactly was the abattoir on Wiseton Road? It looks as though it could have fitted into the large garden on the north side of Wiseton Rd, but in fact I think it was on the other side - behind where Sainsbury's Local is today.
These had been built speedily to house some of the many people who had been bombed out during the war. Along with other prefabs on the edge of many parts of the Common, including nearby Bolingbroke Grove, they were demolished around [1955?].
[Notice the little dog-leg in the parish and parliamentary etc boundary at the corner of Wiseton Road - the dead-straight ancient [Anglo-Saxon] boundary ran 20 yards or so to the north - it passed between what are now ? and ? Bellevue.]
