Interstate 280 (abbreviated I-280) is a highway that makes up the western and southern portions of the beltway around the Quad Cities of Illinois and Iowa. The freeway starts at I-80 near Davenport, Iowa and ends at I-80 near Colona, Illinois; its eastern part runs concurrent with I-74 to return to I-80. I-280 forms the southern part of a circle around the Quad Cities as well as forming part of a bypass (along with I-80) for U.S. Highway 61 around Davenport. This road is 26.98 miles (43.42 km) long.[1]


Route description

Interstate 280 runs through the following states:



In Iowa, I-280 runs along a mostly rural area for 9.38 miles (15.10 km)[1]. The portion in Iowa begins at the junction with I-80 on the northwest side of Davenport, to the I-280 Bridge over the Mississippi River into Illinois. This segment runs mostly north–south, before turning southeast towards the Mississippi River.


In Illinois, I-280 runs for 17.60 miles (28.32 km).[1][2] It runs southeast from the I-280 Bridge to Milan, where it parallels the Rock River. I-280 joins with I-74 at the Quad Cities International Airport; this concurrency continues for 9.4 miles (15.1 km) before terminating at the I-74/I-80 interchange.


Interstate 280 has been at the center of a few debates regarding its routing. In the early 1990s, the state of Illinois suggested, via AASHTO and ISTEA hearings, swapping the I-80 and I-280 designations around the Quad Cities. The plan would have also changed I-74 to I-174. This was challenged by the state of Iowa, and the idea was dropped.[3]

One of the reasons Illinois pursued the matter was due to the configuration of the eastern terminus of I-280; as a simple cloverleaf interchange, through I-80 traffic (along the north and east branches) was required to exit on both directions. Thru I-74 traffic (along the west and south branches) is also required to exit on both directions. I-280 runs due west from the interchange.
