[edit] Route description
Illinois 251 runs parallel to Interstate 39 and U.S. 51 for most of the length of I-39 in Illinois. Like Illinois Route 351, it can be considered a spur or loop of its parent route, U.S. 51. Illinois 251 terminates about 10 miles (16 km) north of the southern terminus of I-39.
The road parallels the Rock River through Rockford on the east side. Illinois Route 2 follows the west side of the Rock River.
[edit] History
Illinois 251 was established as U.S. 51 was moved onto various highways in Illinois. In the early 1970s, Illinois 251 was moved onto a former alignment of U.S. 51 north of Interstate 90 (Northwest Tollway) through the Rockford area; U.S. 51 then became cosigned with what was then solely Interstate 90. From 1984 to 1992, what is now Interstate 39 opened in segments south to Bloomington.[2] The initial designation of the expressway was U.S. Route 51. As U.S. 51 was moved, Illinois 251 was extended further south to take over the former routing of U.S. 51 from Rockford to near Kappa.
