Workers yesterday started construction on the world's biggest power-transmission expressway.

When completed, the connection - which will bring in hydro-generated power from 2,000 kilometers away in southwest China - will meet one fifth of the city's electricity needs and curb sulfur emissions, Shanghai Daily reported.

The ultra-high voltage direct current (HVDC) power transmission project, the longest and the biggest in the world in terms of transmission capacity, will go online in 2011.
