Interchange 4/20 highway on Route 443 connects the neighborhoods of the north east of the Begin road. The investments in establishing the interchange are over 150 million ILS.
The project includes complex of infrastructure works: water, sewer, electricity, communication and road. The engineering of the road, bridges and ramps are complicated especially since the area is saturated with traffic.
Next steps in the project are North Begin Road (Highway 50), completed a bridge over Highway 50 and pave the ramps up and down the bridge. Another bridge will be built over the Atarot river to the east, and would be built for the continuation of Highway 20 approximately 1 km in length, to connect to the bridge over the Atarot river and the Beit Hanina junction. Highway shall appoint two lanes in each direction.
