Israel's infrastructure is modern and well developed. To cope with its growing population and to improve the functioning of the economy, Israel is making large investments to upgrade its infrastructure. Major projects include the construction of a new terminal at Ben Gurion International Airport; a tunnel through Mt. Carmel to provide a bypass route around Haifa; the Cross-Israel Highway, a major north-south artery; and mass transit systems planned for Jerusalem, Beer Sheva, and the Tel Aviv region.
