The most prominent success of the project includes impeding the further development of alluvial deposit by accelerating the circulation. “Westward expansion” project also realize the image of ancient Westlake once only can be envisage.
	However, the truth of Westlake is far more than the superficial flourish. Since the restoring of Yanggong causeway, previously served as a main traffic vein from north to south of the city. the traffic system was facing enormous pressure. To alleviate this, a underlake tunnel was digged up, which is obviously a potentially fatal damage to Westlake. The tunnel will cause the leaking, settlement, etc.		However, the truth of Westlake is far more than the superficial flourish.
