The route begins at a new junction on Highway 1 west of the Sha'ar Mizrah Junction with Highway 60. Traveling northward, the road includes new entrances to Ramat Shlomo and Shu'afat reaching an altitude of 810 m. It continues along the western slopes of Shu'afat and Beit Hanina above the valley of the Atarot Stream as far as Helet Sinad St. From there the road will proceed northward, intersecting with the new Jerusalem Road 20 and continue through north-west Beit Hanina, finally ending at the Atarot Industrial Park. Rather than through cutting and bridging to cross the many draws along the hillside, the road's alignment will follow a curving route while maintaining a relatively stable grade with minimal engineering.
History
Plans for the road were advanced in 2002 when Moriah Jerusalem Development Corporation approved designs and published tenders for its construction. In 2005, the Israel Ministry af Transport approved financing for more detailed designs and initial clearing and fencing along the route. In 2010, the Jerusalem Municipality announced its intention to purchase land for that purpose. When the road was first proposed, the stated official purpose was to provide an alternative to part of the existing north-south route in the area. Specifically, Shuafat Road suffers traffic congestion during rush hours as a result of the Jerusalem Light Rail which runs along its median. This will be alleviated by several access points to the new road from the west side of Shuafat and Beit Hanina. Palestinian groups point to an additional phrase in the stated purpose which says the new road would provide additional access to Ramat Shlomo and future neighborhoods which are considered illegal settlements by the international community. Construction began in early 2013 beginning at the southern end at Highway 1. During the initial stages of clearing, Moriah Corporation unearthed a previously unknown stone quarry and stonecutters tools dating from over 2000 years ago. According to Irene Zilberbod, excavation director on behalf of the Israel Antiquities Authority, the size and type of cuttings indicated that this particular quarry probably supplied stones for magnificent public buildings. The section from Highway 1 to the first traffic circle opened September, 2014. The next section to the second traffic circle opened November, 2014. The final section of the southern part of Road 21 from Yekutiel Adam Blvd. to Shomaan Street was completed in June, 2020.
