Interstate 74 is a north-south highway in Iowa. This highway forms the middle expressway artery in the Quad-Cities. I-74 enters Iowa from Illinois at Bettendorf and ends at Interstate 80 in Davenport.
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.*

BGS on EB I-80 for I-74. Due to construction on the Illinois side, I-74 is actually detoured on to local street. This being, most traffic is encouraged to stay on I-80 to by-pass the downtown areas. (April 2003)
