Arkansas Highway 612, known as the Springdale Northern Bypass, is the temporary designation of the future U.S. Route 412 (US 412) bypass around Springdale in the U.S. state of Arkansas. It currently consists of a four-lane freeway from a temporary at-grade intersection with Highway 112 in Springdale to an interchange with Interstate 49 (I-49) in Springdale.
Once completed, the highway is planned to act as a bypass of US 412 around Springdale, relieving traffic and improving travel between the city and Northwest Arkansas National Airport. The highway is planned to be a four-lane Interstate-standard divided freeway which will eventually be designated as I-42. There is no funding to complete the bypass entirely.
