Caijiagou Railway Bridge Yifu
渝万高铁蔡家沟特大桥
Liduzhen, Chongqing, China
(623) feet high / (190) meters high
551 foot span / 168 meter span

Caijiagou Railway Bridge Yifu is the third of three massive parallel high speed railway viaducts that cross Caijia Creek between Fuling and Chongqing Cities. All 3 of these colossal structures are arguably the largest high level railway viaducts ever built with most of their two kilometer lengths measuring over 100 meters high.
The pier on the third Caijiagou Railway Bridge on the HSR line between Wuhan and Chongqing is 165 meters tall surpassing the older Caijiagou Railway viaduct's pier height of 139 meters and the Caijiagou Railway Bridge Yuwan pier height of 150.5 meters. Only the 164.5 meter pier of the Xiangjiang Railway Bridge, the 154 meter pier of the Yuanjiang Railway Bridge and the 150 meter pier of the Luozehe Railway Bridge are comparable. The side piers are also very tall at 161.5 and 144.5 meters supporting the 3 main spans of 168 meters.
There are 20 piers with a height of more than 50 meters and 5 piers with a height of more than 100 meters on the Yifu railway viaduct.
The Yifu span arrangement is 2x32 meters simply supported box girder + 2×44 meters of T-span, 2x72 meters + 92+3×168+92 meters main rigid frame spans + 3 x (2x62) meters T-span + 72+128+72 rigid frame + 2×62 meters T-span + 2x80 meter T-span + 2x32 meters simply supported box girder.
The main bridge pier pile foundations are 2.8 meter bored cast-in-place piles with a maximum pile length of 49.5 meters.
The Yifu viaduct measures 2005.788 meters in length while the second Caijiagou Yuwan Railway Bridge has a length of 2,133 meters while the Yuli line crossing is 2,105 meters long.
The entire Chongqing to Wuhan HSR line has approximately a dozen bridges that exceed 90 meters in height.

These are six of the largest high level railway viaducts on earth!
