Interstate 555 (I-555) is an Interstate Highway that connects Turrell, Arkansas, at I-55 to Jonesboro at Arkansas Highway 91 (Hwy. 91). I-555 travels along what is currently U.S. Route 63 (US 63) for its entire route. That highway was upgraded in the 2000s to Interstate Highway standards. I-555 is the second Interstate with all three digits the same, to exist, the first to be signed as an Interstate (I-444 in Oklahoma is unsigned).
The road provides a limited-access highway corridor between Memphis, Tennessee, and Arkansas's fifth largest city, Jonesboro.
The I-555 route was approved on January 10, 2001, consisting of upgrading the section of US 63 between Turrell to Jonesboro to interstate standards.
According to the 2007 Arkansas state highway map, only a segment from Tyronza to Gilmore was not yet up to freeway standards. However, as of August 5, 2007 the Hwy. 135 interchange on that section, the last one remaining, is open, thus making the route a true freeway.
A few mainline bridges between Marked Tree and Turrell are from the original two-lane US 63 and are narrower than current Interstate Highway standards, but I-530 was approved in 1999 despite having a similar issue.
