Interstate 164 (I-164) was a spur highway of I-64, between that highway and U.S. Highway41 (US41) in Evansville, Indiana. I-164, also known as the Robert D. Orr Highway, had a total length of 21.24 miles (34.18km) and was the only auxiliary route of I-64 in Indiana. Requested as an Interstate and approved in 1968, the freeway was opened to traffic on August 2, 1990.[citation needed]
Currently signed as I-69, I-164 was signed north–south as it wrapped around the east side of the metropolitan area and then east–west as it curved to meet US41. West of US41, the freeway became Veterans Memorial Parkway, an urban surface arterial which provides a direct connection with Evansville's central business district. The highway paralleled the Ohio River as it passed around the south side of Evansville. About 4 miles (6.4km) after Veterans Parkway, I-164 turned north and almost immediately had an interchange with SR66, locally known as the Lloyd Expressway, which is a mostly limited access surface arterial through Evansville with several at grade intersections. After passing SR62 (Morgan Ave), the route exited Evansville and continued through suburban area. Near the northern end of the route, SR57 started a brief concurrency with the Interstate Highway. I-164 ended at a cloverleaf interchange with I-64, and SR57 continued north as a two-lane surface highway. However, in the mid-2000s, construction of I-69 north of I-64 began, and now continues north on a concurrency with SR57.
