Don't worry bro. Being part of Shanghai city, Chongming Island is well taken care of! Since 2009 we have a new infrastructure:
Shanghai Yangtze River Tunnel and Bridge
Shanghai Yangtze River Tunnel and Bridge - Wikipedia, the free encyclopedia
It is a
bridge-tunnel complex across the south fork of the
Yangtze River near the river mouth in Shanghai. The tunnel connects the
Pudong District of Shanghai on the south bank of the river with
Changxing Island, while the bridge connects Changxing Island with
Chongming Island. In combination with the
Chongqi Bridge (opened in December 2011), which connects Chongming Island to the north bank of the Yangtze, the bridge-tunnel complex forms the final crossing of the Yangtze before it empties into the
East China Sea. Built from 2005 to 2009 at a cost of 12.6 billion
yuan (US$1.84 billion), and opened on 31 October 2009. Their combined length is 25.5 km, forming part of the
G40 Shanghai–Xi'an Expressway.

Cross-River Tunnel Section
It is 8.9 kilometres (5.5 mi) in length, and has two stacked levels. The upper level is for a motorway, and has three lanes in each direction. The lower level is reserved for a future
Shanghai Metro line. The tunnelling was completed using four world's biggest
tunnel boring machines, the largest of which was 15.43 metres in diameter, 135 metres long, and weighed 2,300 tonnes.

Cross-River Bridge Section
It consists of two long
viaducts with a higher
cable-stayed section in the middle to allow the passage of ships. The total length is 16.63 kilometres, of which 6.66 kilometres (4.14 mi) is road and 9.97 kilometres bridge. The overall shape of the bridge is not
linear but slightly
sigmoid ("S" shaped). The central cable-stayed
span is about 730 metres, the longest span of any bridge in Shanghai, and the
10-th longest cable-stayed span in the world. The bridge has three road lanes in each direction, Room on both flanks of the bridge is reserved for a future
Shanghai Metro line, so total deck width is 35.3 m.
