According to Prof. Ronny Reich, “In the Second Temple Period, pilgrims would begin the ascent to the Temple from here. This is the southernmost tip of the road, of which a section has already been discovered along the western face of the Temple Mount.”
The current excavation has been concentrated in a very narrow strip (1-2 meters in width) in the western sections of the road. Essentially, the excavation work removed the earth that had been filled in by previous excavators over the sections they already discovered. This section of road is built in the Second Temple style, which comprises alternating wide and narrow steps.
