The last section of the highway, between Olga Junction and Haifa, opened in 1969. When this section opened it was the first freeway in Israel. Deteriorating road conditions caused by years of neglect led to this section being downgraded from its original freeway status. Road signs on this section are still blue (as opposed to green on regular highways), however there are a few signs indicating an entrance or exit from a freeway and the maximum speed limit is 90–110 km/h, which makes it an Israeli freeway.
