Dramatic moment 23-year-old mile-long bridge is reduced to rubble in seconds during a controlled demolition
October 01 2018, 5:11 PM
A mile-long bridge in south-east China was destroyed in a controlled explosion today to make way for the construction of a taller, wider overpass.

The busy Ji’an Ganjiang Bridge stretches over the Gan River in Jiangxi province and could no longer meet the traffic demands of the growing population. Local authorities approved plans to bring down the 23-year-old bridge after recent years of repairs and improvements failed to improve the structure’s safety, according to reports.

The multi-lane motorway was demolished at 10:18am local time as hundreds of residents watched on. Workers attached several tonnes of explosives on the bridge’s four main columns and 61 piers. Video footage filmed by witnesses show the massive motorway – spanning 1,577 metres (5,173 feet) across the river – being reduced into a cloud of smoke and debris. Following a large bang, the structure disappeared in seconds into the waters of the Gan River.

Construction for the Ji’an Ganjiang Bridge began in September 1993 and opened to traffic in December 1995. However, an increasing number of overweight vehicles crossing the bridge, among other factors, has been causing permanent damage to the structure. Years of repairs and improvement works failed to eliminate the damage to the bridge, which has been listed as ‘dangerous’ in a structural evaluation.

Plans to rebuild the bridge has been approved by the Centre for Urban Planning and Construction Committee last November. The new bridge will span 2,211 metres (7,253 feet) and will have six lanes and non-motorised access. Work on the new project will begin in January next year after the rubble has been cleared from the waters. The overpass is expected to open to traffic in June 2021.
