The five kilometre stretch of Highway 65 east towards Afula is called Kvish HaSargel, lit. 'the Ruler Road', since it is virtually flat and straight as a ruler.
This is currently a very important junction for the residents of the northern district of Israel, because it sits at the entrance to the Wadi Ara mountain pass which connects the North to the Trans-Israel Highway (Highway 6) and other highways in Israel's coastal plain and, by that, to the rest of the country. Its importance slightly diminished when Highway 6 was completed all the way to the Ein Tut interchange near Ramot Menashe in 2009. The junction and Highway 66 can now be used as an alternate route for reaching Highway 6 via another mountain pass, Wadi Milek, located northwest of Wadi Ara.
