By the 1980s, Northern Virginia and the Hampton Roads region had achieved the greatest growth and prosperity, chiefly because of employment related to Federal government agencies and defense, as well as an increase in technology in Northern Virginia. Shipping through the Port of Hampton Roads began expansion which continued into the early 21st century as new container facilities were opened. Coal piers in Newport News and Norfolk had recorded major gains in export shipments by August 2008. The recent expansion of government programs in the areas near Washington has profoundly affected the economy of Northern Virginia whose population has experienced large growth and great ethnic/ cultural diversification, exemplified by communities such as Tysons Corner, Reston and dense, urban Arlington. The subsequent growth of defense projects has also generated a local information technology industry. In recent years, intolerably heavy commuter traffic and the urgent need for both road and rail transportation improvements have been a major issue in Northern Virginia. The Hampton Roads region has also experienced much growth, as have the western suburbs of Richmond in both Henrico and Chesterfield Counties.
