| 摘要： | The area of the country known as the Quad Cities has long been a key transportation hub for national commerce: first as a port on the Mississippi River, then as a critical railroad crossing (and the site of the famous court case in which then-lawyer Abraham Lincoln defended the railroad's right to cross the river), and finally as an integral part of the nation's highway system in the Midwest. For the Quad Cities region - Bettendorf and Davenport in Iowa and Rock Island, Moline, and East Moline in Illinois - that integral link is Interstate 74, which has been carried across the Mississippi by two iterations of the I-74 bridge. The first, a twin-span suspension bridge built in the 1930s (westbound to Iowa) and the 1950s (eastbound to Illinois), was a shoulderless, four-lane bridge (two lanes per span). Because the lanes were substandard in width and there were no shoulders, cars traveled right next to the stiffening trusses - an uncomfortable driving experience for some. As the Quad Cities population increased, it became evident that traffic demands would soon outgrow the bridge's capacity and it would need to be replaced. |
