exist in this location. From the 1820s onwards, the earlier lines of road were upgraded and although short sections of Cox's Road were later adopted as parts of the local road network (eg. part of Burke Road, Linden and Old Bathurst Road, Woodford) most of the original Cox's Road appears to have gradually gone out of use in the Linden area during the 1830s Description William Cox had been instructed by Governor Macquarie only to open a rough cart road, so that the new lands found in the western plains would be symbolically open. The road from Emu Ford to Bathurst, a distance of was completed in only six months. Macquarie's instructions specified that the road should be at least wide in order that two carts would be able to pass each other, and that the timber should be cleared on each side so that the road corridor was wide. Stumps were to be grubbed out and any holes should be filled in. This was the method adopted in relatively easy terrain, although later travellers reported that the stumps had not always been removed and the surviving physical evidence shows relatively few locations where the extant road conforms with the dimensions specified in the instructions. The Tollgate Drive section of Cox's Road is the first of the more intact surviving sections of the 1814 road which are encountered within the Blue Mountains LGA. The 1814 road occupies the crest of the ridge. It extends for over beside and overlapping with an unsurfaced access road along the top of the ridge and also partly within adjoining private properties. The modern roughly formed vehicular access track with some subsidiary diversions, leads off Tollgate Drive/Railway Parade. The modern unsurfaced tracks themselves cross, and in some places partly overlie, the earlier Cox's Road formation. The western end of the access track commences at Railway Parade where it climbs a short steep rise surfaced with loose stones. Where there are rocky outcrops beside the road it features several sections of low hand-cut gutters and kerb-lines (). The cuttings are between in height and where they mark both sides of the road they are apart, roughly conforming with Governor Macquarie's requested width of "". Most of the cuttings have vertical faces and feature sharp pointed marks indicating the use of chisels or pick-axes during construction. Other marks suggest the use of a long round iron spike
