The Greenville Bridge is a cable-stayed bridge over the Mississippi River carrying US 82 and US 278 between Greenville, Mississippi and Lake Village, Arkansas. When it opened in 2010, it was the fourth longest cable-stayed bridge in North America. The Benjamin G. Humphreys Bridge, the first bridge to connect the two towns, had become functionally obsolete. Its narrow road had only two lanes with no shoulders. Because of its location near a sharp bend in the Mississippi River, the bridge had become a hazard to river traffic; barges and towboats frequently collided with it. In 1994, a study concluded that a new bridge was needed and the old one should be torn down. Construction was begun in 2001 and the new bridge opened in 2010. In 2011, the process of removing the old bridge began. ==Description== Opened in 2010, the Greenville Bridge carries US 82/278 over the Mississippi River between Greenville, Mississippi and Lake Village, Arkansas.
