The construction of the shorter of the two bridges, across Golden Horn Bay in central Vladivostok, began in July 2008.
In April, the final section was installed to complete the bridge across Golden Horn Bay.
The Golden Horn Bridge was officially opened on August 11, but only pedestrians were allowed to use it the first two days.
The larger of the two bridges, which is the world's largest cable-stayed bridge, is built across the Eastern Bosphorus Strait and connects Vladivostok with Russky Island.
In April, workers added the last panel of the 1,104-meter bridge to Russky Island.
The bridge to Russky Island has the highest pylons and longest stays of any bridge in the world.
The bridge to Russky Island (pictured) has been compared to San Francisco's Golden Gate Bridge.
