After over two years of closure and maintenance, Nanjing Yangtze River Bridge is set to re-open on Dec. 29. 

The Guinness Book of World Records bridge once listed it as 'the world's longest road-rail bridge.' 

The newly-renovated bridge surface gleams like new. 

All street lights on the bridge's surface have been replaced with light-emitting diodes. 

Cast-iron relief sculptures are embedded in the bridge railings.

The sculptures at the bridge's ends remind people of the years when the bridge was under construction. 

Unflappable red flags bracket the bridgeheads.
