NS 4307 26 - NS 430 730. A causeway 7.2m wide runs north from the Longhaugh Lodge-Old Bishopton track to curve through the river dyke and pass as a recognisable mound through river eroded carse to the beach. Beyond this, through silt, it proceeds as a 10.7-10.9m wide gravelly mound, over which has been built a cobbled way leading to the Longhaugh Light (NS 4286 7335). It aligns with a recognisable road mound on the north bank.
NS 425 724 A band of small cobbles in gravel 15.3m wide between kerbs with on each side shallow 'ditches' 1.3m wide lies on the north side of the railway cutting 100m east of the stream flowing from Slateford Lodge. If this is a road it is running from the region of Whitemoss Fort Annexe ( ) to the junction of the Longhaugh beach road with
the Old Bishopton track (NS 435 725).
