Wara Jarso (Oromo: Warra Jaarsoo) is a woreda in the Oromia Region, Ethiopia. Part of the North Shewa Zone, Wara Jarso is bordered on the south by Kuyu, on the west by the Muger River which separates it from the [[West Shewa Zone]], on the north by the Abay River which separates it from the Amhara Region, on the northeast by the Jamma River which separates it from Dera, and on the east by Hidabu Abote. Towns in Wara Jarso include Filiklik, Gohatsion and Tullu Milki.
Wara Jarso is connected to Dejen in Amhara by the Abay Bridge, which also carries the Addis Ababa-Bahir Dar highway; before the bridge was erected, the Abay was crossed at the Shefartak ford (at 10° 5' N 38° 17' E). A new bridge, the Hidasie Bridge, was dedicated 10 September 2008 at the presence of senior government officials and other guests. Funded by the Japanese government at a cost of 319.3 Birr, the Hidasie Bridge is 303 meters long and part of the new Addis Ababa-Dejen road.[1]
