Tianjin Economic and Technological Development Area

Tianjin Economic and Technological Development Area (天津经济技术开发区, TEDA) is an area in Tanggu District in Tianjin. It was formed in late 1984.

TEDA, pronounced nearly the same in Mandarin Chinese, is a vast area by the seaside. It contains a port, business buildings, urban residential areas, and an extensive transportation network.

The area's largest bridge is the Haihe toll bridge. It virtually links one end of the area to the other part.
