In the late 1990s, the Israel Ministry of Transport planned to construct Highway 45 from
Highway 1 near
Ben Gurion International Airport through the
West Bank north of the Modi'im Stream passing slightly north of
Beit Horon and
Beit Ur al-Fauqa to the Atarot Industrial Park in Jerusalem. The current Route 443 just south of these towns as well as political considerations has made that plan irrelevant, leaving the small portion of Highway 45 between Giv'at Zeev and Atarot completed in 2003. Excavations in the hillsides performed in the 1990s can still be seen just northwest of Givat Ze'ev junction. Furthermore, an easterly extension is still envisioned which would continue from Atarot and connect with
Route 437 and the
Eastern Ring Road. The construction of the
West Bank security barrier along the right of way of Highway 45 east of Atarot and the Qalandia security checkpoint places limitations on that plan. A possible solution would involve tunnels and bridges. In 2017, the Israel Ministry of Transportation announced a five-year plan which includes just such an extension of this section with grade separation at the Qalandia Checkpoint. In the meantime, the completion of
Jerusalem Road 20, further south, provides an alternate route to 437. Further east, 45 is intended to eventually reach the border with
Jordan north of the
Dead Sea to connect with the road to
Amman. ==Junctions and Interchanges (West to East)==
