Wan Ban Bridge originally named Hsizang bridge which located at downstream of Hsintien creek in Tamsui River, is a very important bridge due to connect with both Wanhua District in Taipei City and Banqiao District in New Taipei City. Its main bridge is a 5span (55+110 +110 +110 +55) continuous prestressed concrete arch bridge, with total 440m long. The 2 half arches at ends and 3 full arches in the middle with upside down triangular shape pier supports has created a very elegant, natural and esthetic configuration.
