World’s longest bridge closer to completion
The world’s longest bridge under construction moved one step closer to completion with building of the main structure finished.
With the final expansion joint laid down, the 55-km (34-mile) Hong Kong- Zhuhai- Macao Bridge marked a milestone on Tuesday morning.
The bridge is comprised of the offshore bridge and underwater tunnel, boundary crossing facilities in Hong Kong, Zhuhai and Macao and routes connecting the three cities.
The bridge’s main structure is made up of the 6.7-km (4.16mile) underwater tunnel and a bridge spanning 22.9-km (14.22 miles). Artificial islands are built at both ends of the tunnel to allow the passage of large ships.
The bridge, planned in 1983, is expected to be completed by the end of next year at the earliest. Once it is completed, the commuting times between Hong Kong and Zhuhai or Macao will be reduced from 3 1/2 hours to 30 minutes.
