For the last seven years, researchers from the Israel Antiquities Authority have been involved in the removal of large amounts of debris that have accumulated in the largest water channel from the Second Temple period.
The route of this channel follows that of the Tyropoeon Valley. The channel is located beneath the main paved and stepped road which traversed Jerusalem in those days. The road passed next to the Western Wall in the north and down to the Siloam Pool in the southern portion of the City of David. At no point, does the route of either the road or channel pass beneath the Temple Mount.
