Archaeological investigations along the Cross-Israel Highway were conducted in several stages. First, the main tells along the projected route were marked and the route was planned to bypass them; then, comprehensive surveys commenced, during which all sites were documented, including recommendations as to which of them should be excavated and to what extent. Trial excavations followed, in cooperation with the archaeological institutes of the universities. Subsequently, salvage excavations were conducted in accordance with the data retrieved from the surveys and trial excavations. The intensive surveys and excavations along the Cross-Israel Highway revealed sites that had been hitherto unknown and, in addition, provided important data concerning previously documented sites.
