erected at village entrances, 59 were always closed. The checkpoint system did not ease up after the Oslo Accords, but was strengthened after them, which has been interpreted as suggesting their function is to assert control over Palestinians, and as a sign of an unwillingness to yield ground in the West Bank. According to PA Health Ministry statistics relating to the period from 2000 to 2006, of 68 Palestinian women who gave birth to their children while held up at checkpoints, 35 miscarried and 5 died while delivering their child there. Machsom Watch accumulated over a mere five years (2001–2006) some 10,000 eyewitness reports and testimonies regarding the innumerable difficulties faced by Palestinians trying to negotiate West Bank checkpoints. Transportation infrastructure is particularly problematic as Palestinian use of roads in Area C is highly restricted, and travel times can be inordinate; the Palestinian Authority has also been unable to develop roads, airports or railways in or through Area C, while many other roads were restricted only to public transportation and to Palestinians who have special permits from Israeli authorities. At certain times, Israel maintained more than 600 checkpoints or roadblocks in the region. As such, movement restrictions were also placed on main roads traditionally used by Palestinians to travel between cities, and such restrictions are still blamed for poverty and economic depression in the West Bank. Underpasses and bridges (28 of which have been constructed and 16 of which are planned) link Palestinian areas separated from each other by Israeli settlements and bypass roads" Israeli restrictions were tightened in 2007. There is a road, Route 4370, which has a concrete wall dividing the two sides, one designated for Israeli vehicles, the other for Palestinian. The wall is designed to allow Palestinians to pass north–south through Israeli-held land and facilitate the building of additional Jewish settlements in the Jerusalem neighborhood. , a plan for 475-kilometer rail network, establishing 11 new rail lines in West Bank, was confirmed by Israeli Transportation Ministry. The West Bank network would include one line running through Jenin, Nablus, Ramallah, Jerusalem, Ma'aleh Adumim, Bethlehem and Hebron. Another would provide service along the Jordanian border from Eilat to the Dead Sea, Jericho and Beit She'an and from there toward Haifa in the west and in also in a northeasterly direction. The proposed scheme also calls for shorter routes, such as between Nablus and Tul Karm in the West
