Very interesting; today’s view has little resemblance to the view that Jack Myers would have had as he made his way up the hill. The road surface is one major difference of course but the corners are also quite different.
Today’s road-building techniques include substantial cutting, filling and drainage; this was not done in early roads where horses and carriages simply followed the natural “flow” of the topography.
(Forest roads still do; that is why they are so satisfying to drive on).
The constructed road often pre-dated the laying-out of the cadastre (the boundary lines of land subdivision) so the original cadastre is angular as the surveyor followed the road alignment.
Motor cars brought-about a demand for less-winding roads; as cars became faster the demand for “easing” of corners grew rapidly. Sometimes two or more stages of “easing” can be seen to have been done over a long period. This easing is apparent on maps as the original (commonly 20-metre-wide) road reserve is no longer parallel-sided.
The corner in the Jack Myers photo has clearly been changed over the years; he is negotiating an S-bend that is now just a right-hander. Here is a “guesstimate” of how this happened;
The house visible in the photo is shown and the irregularity of the road boundaries indicates that much re-alignment has taken place.
There is another interesting example near the top, at the point from which the postcard photo was taken.
I have “ghosted” the airphoto in behind the cadastre; the present road and the lookout/monument at the top can be seen.
Given the topography (the bank would only have been cut away when the present road was built) there was probably not much "spare" road at the top for parking of cars; I would guess that, possibly, private land or just an extension of the road after the finish would have been used.
The original 20-metre road reserve can be seen; the present road departs from the reserve in the plan centre, probably because the Council built the road under a “Permit to Enter” and never got around to finalising the new boundaries (there are myriad examples of this).
A good deal of fill would have been required to ease this and other corners outwards along the gully; this would have come from banks such as the one at the top where the corner has been eased into the hillside.
There is evidence of the old road at this point in the final photo of my post, where the power/’phone pole can be seen.
The hill is an easy cruise for today’s Bowral Bulldozers; it would have been a considerably different story for Myers and others who fought their way up.
