Milecastle 64 was located and excavated in 1962. It was found to be a short axis milecastle, and measured internally 17.8 metres by 14.6 metres. The walls had been extensively robbed of stone. The north gateway, which was 3 metres wide, had been blocked at some stage. A cobbled road 5 metres wide ran through the centre of the milecastle.
Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 64 are known as Turret 64A (grid reference ) and Turret 64B (grid reference ). None of the turrets between Milecastles 59 and 72 were sought or identified prior to 1961, and the exact locations of turrets 64A and 64B have not been found.
