Highway 4 (Israel) is a north–south arterial route along the Mediterranean coastal plain of Israel connecting the southern coastal city of Ashdod with the northern border area near Rosh HaNikra. The road serves as an alternative to the Coastal Highway and links or parallels sections of Highway 2 (Israel), Highway 20 (Ayalon Highway), and Highway 6 (Trans-Israel Highway). Highway 4 traverses major urban centers including Tel Aviv, Herzliya, Netanya, and Haifa, and intersects rail corridors such as the Tel Aviv–Haifa railway.

Route description

Highway 4 begins near Ashdod railway station and proceeds northward through the municipality of Ashdod before entering the metropolitan area of Gush Dan. In the south-central segment it passes through or adjacent to Rishon LeZion, Holon, and Tel Aviv-Yafo, intersecting the Ayalon Highway and the Ben Gurion Airport access routes. In the northern coastal plain it runs near Herzliya Pituah, Herzliya, Netanya, and Hadera, then continues to the Haifa Bay area, skirting neighborhoods such as Bat Galim and industrial zones including the Haifa Bay. The highway climbs the Carmel range toward Haifa and proceeds northward past Kiryat Haim, Kiryat Bialik, and Akko suburbs before terminating near Rosh HaNikra at the Israel–Lebanon border approach. Major interchange links include connections to Highway 2 (Israel), Highway 20 (Ayalon Highway), Highway 1 (Israel), and local arterial routes serving the Port of Ashdod and the Port of Haifa.

History

The corridor now occupied by Highway 4 traces historic coastal routes used during the Ottoman Empire and the British Mandate for Palestine. During the Mandate period infrastructure projects formalized the road network connecting Jaffa, Haifa, and Acre. After the establishment of Israel in 1948, the road was upgraded to accommodate growing civilian and military traffic, with successive expansions during the 1950s and 1960s that paralleled national development plans led by authorities such as the Israel Ministry of Transport and Road Safety. The emergence of the Hadera power station and expansion of the Port of Ashdod influenced realignment and widening works. In later decades intersections were modernized to interchanges during administrations that included major public works under the National Infrastructure Plan.

Major junctions and interchanges

Key junctions on Highway 4 include the southern terminus at the Ashdod Port access, the interchange with Highway 41 (Israel) and Highway 42 (Israel), the Ayalon/Highway 20 (Ayalon) complex near Tel Aviv Savidor Central Railway Station, the junctions serving Herzliya Pituah marinas, the Netanya central interchanges, the crossing with Highway 2 (Israel) near Hod HaSharon approaches, the Hadera interchange complex linking the road with access to the Hadera West railway station, and the approaches to Haifa Bay including the connections to roads serving the Technion – Israel Institute of Technology and the Rambam Health Care Campus.

Traffic and usage

Highway 4 functions as both a commuter arterial and freight corridor, carrying passenger vehicles, buses operated by operators such as Egged and Kavim, and heavy goods traffic serving the Port of Ashdod and Port of Haifa. Peak-hour congestion is pronounced in the Gush Dan segment around Tel Aviv and on approaches to Haifa, especially where the highway parallels rail lines used by Israel Railways. The route is part of strategic logistics chains linking industrial zones like Kiryat Ata with distribution centers in Lod and southern Israel. Traffic management involves coordination among bodies including the Israel Road Company and municipal traffic departments of Tel Aviv-Yafo and Haifa.

Infrastructure and upgrades

Over time Highway 4 has been subject to grade-separation projects, carriageway widening, resurfacing, and the installation of modern traffic signaling systems funded by national agencies. Projects have included conversion of busy intersections into interchanges, construction of pedestrian bridges adjacent to urban centers such as Rishon LeZion and Netanya, and the addition of auxiliary lanes to improve freight flow to the Ashdod Port. Some upgrades were coordinated with national initiatives like the expansion of Highway 6 (Trans-Israel Highway) to redistribute traffic. Engineering works have required environmental assessments due to proximity to sensitive coastal ecosystems near Nachsholim and historic sites such as Caesarea.

Incidents and safety issues

Highway 4 has experienced traffic collisions ranging from minor incidents to multi-vehicle accidents influenced by congestion, high-speed segments, and complex junction geometries near urban centers. Safety campaigns by the Israel Police and road-safety NGOs have targeted enforcement of speed limits, seatbelt use, and commercial-vehicle standards. Sections near industrial ports have additional risks associated with heavy truck traffic and hazardous-material movements overseen by agencies including the Ministry of Environmental Protection. Some stretches have been identified in government road-safety audits for further engineering interventions and enforcement enhancements.

Cultural and economic significance

The highway serves as a spine connecting cultural, educational, and economic hubs such as Tel Aviv University, the University of Haifa, the Carmel Market, and museum districts in Jaffa and Haifa. It supports tourism flows to heritage sites including Acre (Akko), Caesarea, and the Rosh HaNikra grottoes, while underpinning economic activity at the Port of Ashdod and the Haifa Bay Industrial Zone. The route figures in urban planning discussions about sustainable mobility in metropolitan areas like Gush Dan and coastal development strategies affecting municipalities such as Netanya and Herzliya.
