Interstate 164 (I-164) is a spur highway of Interstate 64, formerly between that route and U.S. Route 41 (US 41) in Evansville, Indiana. I-164, also known as the Robert D. Orr Highway, had a total length of 21.24 miles (34.18 km). Requested as an Interstate and approved in 1968, the freeway was opened to traffic on August 2, 1990.
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 US 41. West of US 41, 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 four miles after Veterans Parkway, I-164 turned north and almost immediately intersected SR 66, locally known as the Lloyd Expressway, which is another surface arterial through Evansville. After passing SR 64 (Morgan Ave), the route exited Evansville and continued through suburban area. Near the tail north end of the route, SR 57 started a brief concurrency with I-164. I-164 ended soon after at a cloverleaf interchange with I-64. At the time I-164 was built, SR 57 reverted to a two-lane surface highway but in the mid 2000s, construction of I-69 north of I-64 began.
