and Interstate 88 for most ground transportation, but the original route remains. In Sterling, IL 2 begins as a one-way pair. Near the Sinnissippi Mounds, the two one-way roads merge into a two-way road. From Sterling to Dixon, IL 2 largely follows a portion of

and then back southeast to IL 2 just northwest of Dixon. Just north of Dixon, both routes run concurrently with US 52 and IL 26. They then cross the Rock River to get to downtown. In downtown, IL 2 branches off northeast from the other two routes. At Grand Detour, IL 2 transitions from following the south/east bank of Rock River to the north/west bank via a bridge. Further north, it passes through Castle Rock State Park, IL 64 at the

, IL 2 turns north. At this point, it largely parallels IL 251 for the rest of the route which is east of the river. It then meets US 20 at a diamond interchange (formerly a cloverleaf interchange). As IL 2 gets closer to downtown Rockford, another split occurs. Northbound traffic continues on Main Street, then east on Chestnut Street (US 20 Business), then north on Wyman Street, then west on Park Avenue near the site of Beattie Park Mound Group, and then back north on Main Street before merging. Southbound traffic has to turn west onto John Street, then south on Church Street, and then east on Cedar Street before merging. In Rockton, IL 2 transitions from the west side of the river to the east side again. Further north, IL 75 runs concurrently with IL 2 from Rockton to South Beloit. Before IL 2 transitions into WIS 213, IL 75 branches out to the east. Then, IL 2 crosses a railroad crossing and then Turtle Creek. It continues further until it reaches the Wisconsin state line.
