Highway 20 (Israel)

Highway 20 (Israel), also known as Ayalon Highway (Hebrew: נתיבי איילון, Netivei Ayalon, lit. Ayalon Routes), is a major controlled-access highway in Israel. It runs along the eastern border of Tel Aviv from north to south and connects all major highways leading to the city. The Ayalon Highway is Israel's busiest highway and is a central component of the country's road network.

The highway follows the route of the Ayalon River, situated between the river and the eastern neighbourhoods of Tel Aviv. It is typically eight to ten lanes wide for most of its length, with wider sections in specific interchanges.

Its construction began in the 1970s and continues in phases, with ongoing projects aiming to improve traffic flow and capacity. The Ayalon Highway is a critical artery for commuters traveling to and from the Tel Aviv metropolitan area and plays a vital role in the Israeli economy. The highway features sophisticated traffic management systems including cameras and variable message signs providing real-time traffic information to drivers. Numerous interchanges connect the Ayalon Highway to other major roads and urban areas.
