I-630  

It’s no secret that traffic demands at the I-430/I-630 interchange in west Little Rock, now referred to as the “Big Rock Interchange,” have dramatically changed over the years. The interchange opened in 1977 before there was a Chenal Boulevard or a Financial Center Parkway, and there was virtually no development west of I-430. Traffic volumes on I-430 and I-630 in the vicinity of the interchange have quadrupled since it opened.

Work is underway to modify the interchange to more efficiently accommodate current and projected future traffic volumes. This site was created to provide information about the project.

The name “Big Rock Interchange” is derived from the large rock formation in the southeast quadrant of the interchange that was uncovered during construction. Rather than use explosives or some other method to remove the unexpected feature, the decision was made to leave the unique and distinctive formation in place. Hence the name, the “Big Rock Interchange.”
