A road is shown on maps accompanying the sales particulars for the Ynyslas Estate dating to 1910 (Cardiganshire Sales Particulars 51 and 51A, National Library of Wales) and is likely to have been installed as part of seaside resort development plans in the late 1890s. The road was upgraded and concreted by the military to service the rocket fuel research establishment.
