Depending on how you count it, the Causeway is still the big one. The span over Lake Pontchartrain is the longest bridge in the world, in terms of measuring over water from one point to another.

The Causeway is a straight line, after all. It’s competitor in China is technically longer, although that one is curved.

No matter that it spans less water than our Causeway.

The Chinese bridge is nevertheless another in a series of engineering marvels.

Their Great Wall of bridge-building is the 26-mile Jiaozhou Bay bridge, linking the port city of Quindao to an offshore island.

The new bridge in China was built over four years, but it is only one of many: Experts said seven of the 10 longest bridges in the world are in China, and an even longer sea bridge is under construction, linking southern Guangdong province with Hong Kong and Macao.

The point is that the Chinese are investing —heavily — in infrastructure to improve their economy.

While the average American is still far better off than the average person in mainland China, the economy there is a huge one that its communist government, unburdened by the complaints of the citizenry about taxes, believes can grow through investment in public works.

From high-speed rail to airports to bridges and other public works, the Chinese projects are becoming showplaces for civil engineering in the world.
