The Chesapeake Bay Bridge-Tunnel runs across a large water expanse with the Chesapeake Bay on one side and the Atlantic Ocean on other.
Before the bridge (build), ferries (渡船) carried 50 to 60 cars a time across the almost 18 miles of water. It took 90 minutes, and bad weather or rough waters sometimes delayed the ferry. As time went by, more people wanted to get across the bay quickly and on a (rely) schedule. So in 1960, thousands of people began work on the engineering wonder.
The bridge was completed in 1964. But you could say that it's never really complete. Johnson, who (work) on the bridge for 20 years, and his crew go out daily (inspect) the bridge structure, making sure it's safe and functioning. Between 1995 and 1999, more roadway was added, making the bridge two lanes (车道) in each (direct). In the next few years, a new tunnel (隧道) will be added to one of the (original).
To some, the bridge is beautiful, inspiring and a symbol of people can do. But to people such as Johnson, the bridge is (simple) something necessary. It's for someone who might need to go to the doctor's office, buy school supplies or visit a friend.
