One tower over the Jialing

Qiansimen was one of the nine open gates of the Ming wall, a water gate on the Jialing side, and the bridge keeps its name and roughly its line. The crossing begins at Shaanxi Road, runs through a tunnel under the peninsula, comes out beside Hongyadong and crosses the river to Jiangbei; the whole route is about 1.6 kilometres, and the tunnel is about 700 metres, four lanes wide. The twin crossing with the Dongshuimen bridge was planned as one road and rail link, and the pair opened in 2014.

The Jialing has a deep shipping channel that would not take a second tower, so the bridge was designed with a single one, set off-centre so that the 240-metre back span gives a second channel for boats. The main span is 312 metres and the main bridge 720 metres, in openings of 88, 312, 240 and 80 metres. The tower is 18 metres wide at the base, 35 metres at deck level and 7 metres at the top; the deck sits about 60 metres above low water and the tower top 100 metres above the deck. The longest stay cable is 256.85 metres. The towers are of cast-in-place concrete.

Two tracks of Line 6 run on the lower deck and four lanes of city road on the upper, with walkways cantilevered from the box girder. The two bridges share their design and were built in the same years. Rail traffic began in April 2014; the road opened at midnight on 29 April 2015. The design came from a competition held in July 2008 and won by a team led by Man-Chung Tang. Planning for the twin bridges goes back to 1947. An earlier Jialing cableway, opened in 1983, stood on the same alignment; it stopped in 2011 and was demolished in 2013.
