At the foot of the tell, Fields L and N were opened to study the Nabataean and Early Roman structures, which formed part of an extensive settlement running south from the bank of the wadi. A regional survey was also conducted during each field season in an attempt to locate new sites, document the remains of sites previously known, and study the evidence for land use and water management in antiquity. The gate complex included a small tower located north of the east end of the gate, and two units of three rooms, one on each side of the central roadway. The gate's total length is approximately 15.30 m, and it was 15.00 m wide, somewhat smaller than gates of the same style at Gezer, Megiddo, Hazor, and Lachish. A stone paved ramp leads into the gate and forms the threshold.
Benches run along both the east and west sides of the central roadway between the gate rooms.
Work done in 1999 revealed a stone-lined drain, and a second stone threshold at the inner, or southern end of the gate. All of the gate rooms and the central roadway at Khirbat Mudayna were roofed and supported second storey rooms. Evidence for the presence of these rooms was in the form of several layers of collapsed ceiling material and wall plaster that had fallen into the lower rooms. An interesting feature of this six-chambered gate is the fourth wall of each chamber on the side of the road. From a study of its construction techniques, it appears that this building was originally built as a new structure, since the piers that formed the main walls were founded on bedrock.
