Highway 23, more-commonly known as the "Carmel Tunnels", are a set of toll tunnels in Haifa, Israel. The tunnels' purpose is to reduce road congestion in the Haifa area and to provide an alternative route for reaching the eastern and central parts of the city, Haifa Bay and the Krayot area to and from Israel's central coastal plain without having to travel through traffic-congested downtown Haifa, having to drive up and across Mount Carmel, or bypassing Haifa from the east – along the edge of the Jezreel Valley. The tunnels cut the travel time from the Haifa South interchange in the west to the Checkpost interchange in the east from 30–50 minutes down to 6 minutes.

Highway 2 is an Israeli highway located on the coastal plain of the Mediterranean Sea. It begins as a major arterial road within Tel Aviv, becoming a freeway as it exits the city northward, continuing to Haifa. North of Tel Aviv, the highway is also called The Coastal Highway.
