Interstate 630 (Wilbur D. Mills Freeway) bisects the city of Little Rock along a 7.4 mile course while providing connections between I-430 and I-30 near Downtown. Replacing the once proposed Eighth Street Expressway, Interstate 630 was constructed during the 1970s but not completed until the mid-1980s.

Construction at the Big Rock interchange with Interstate 430 (Exits 8A-B) and Financial Centre Parkway revised the west end of I-630 to eliminate weaving traffic patterns and increase capacity.

Interstate 630 East
Interstate 630 east begins its 7.4 mile trip across Little Rock at an interchange with Interstate 430, locally dubbed the Big Rock interchange. Modifications to the Big Rock interchange will result in improved access between the two freeways as well as traffic improvements on the approaches. The entire project is scheduled for a summer 2015 completion. 05/07/12, 05/20/14
Some of the major changes to the Big Rock interchange will be the addition of high speed flyover ramps between Interstate 630 and 430 to replace existing loop ramps. The loop ramps will remain for local traffic between Shackleford Road and Baptist Health Drive (Exit 7). Other modifications include additional travel lane capacity along Interstate 630. Use I-430 north to reach Interstate 40 west of North Little Rock. 05/07/12, 05/20/14
