Local reports said that formwork caught fire at one of the towers. State information agency ITAR-TASS reported that firefighters managed to suppress the fire, which spread to an area of 500m2. It took some 11 hours, 38 fire-fighting equipment units and 167 people to bring it under control, according to the reports.
The bridge will cross Golden Horn Bay and is intended to reduce congestion in the city. It will have a 737m-long main span and splayed H-shaped towers supporting two planes of cable stays that carry a steel orthotropic box girder deck.
The Golden Horn Bridge is one of two major cable-stayed crossings that are being built in Vladivostok and are due for completion in time for the Asia-Pacific Economic Cooperation, which will be held next year on Russky Island.
The other crossing is the record-breaking Russky Island Bridge, which is being built over the Eastern Bosphorus Straits. Its 1,104m cable-stayed main span is set to be the world's longest.
