Interstate 74

Interstate 74 is a east-west highway running across Central Illinois. Entering Illinois at the Quad-Cities and exiting just east of Danville, I-74 links several major metropolitain areas in Central Illinois.

Interstate 74 has recieved $67.4 million in federal funding to replace the twin-spans over the Mississippi River in the Quad Cities. In 2002 it was estimated that it would cost $650 million to replace the bridges. The first span was constructed in 1935 by the WPA. Span two was built in 1959. Landmark status was considored in 1999, but it woul cost $3 million a year to maintain the old bridges. The new bridge could have three lanes in each directions, a viewing platform, and a pedestrian trail.*

On Saturday, July 7, 2007, at tanker truck crashed into a bridge carring WB I-74 across the Kickapoo Creek, near Downs, in Mc Lean County. From mid-afternoon to midnight, all lanes of I-74 were closed while the fire and scene was cleared. The heat from the burning gas cause major damage to the WB bridge over the Kickapoo Creek bridge, and minor damage to the northside of the Kickapoo Creek bridge. At midnight, one EB lane of I-74 was re-opened to traffic, while all WB lanes we still closed. WB traffic was put on a temporary detour along U.S. Rt. 136 west to U.S. Rt. 51 north.
