Interstate 894 (I-894) is a auxiliary Interstate Highway in Milwaukee County in the US state of Wisconsin. The route serves as a bypass of downtown Milwaukee, connecting with I-94 at the Zoo Interchange west of downtown and the Mitchell Interchange south of downtown. The route runs concurrently with three other highways for its duration, following US Highway 45 (US 45) from the Zoo Interchange to Hale Interchange as the Zoo Freeway, where it separates from US 45 to follow I-43 heading east to the Mitchell Interchange as the Airport Freeway. In local traffic reporting and casual conversation, it is known simply as "the bypass" or "894", with "41" also being more recently used, as I-894 is entirely concurrent with I-41/US 41. The east–west portion is also concurrent with I-43. I-894 is part of what was proposed to be an extensive freeway network around the Milwaukee area. The Zoo Freeway portion was completed from Beloit Road northward in 1963, and the Airport Freeway and remaining segment of the Zoo Freeway were completed in 1966. I-43 was routed concurrently with I-894 in 1988. Route description I-894 begins at the Zoo Interchange in Milwaukee with I-41, I-94, US 41, and US 45. The highway heads south as part of the Zoo Freeway from this interchange running concurrently with I-41/US 41/US 45. Traffic reports generally refer to this section either as 894 northbound (southbound) or the northbound (southbound) Bypass. North of the Zoo Interchange, I-41/US 41/US 45 continues separately as the north part of the Zoo Freeway. I-894 enters West Allis before its first exit after the interchange; this first exit is a junction with State Trunk Highway 59 (WIS 59), known locally as Greenfield Avenue. After the first three exits, I-894 enters Greenfield. Farther south, I-894 has interchanges with National Avenue, Oklahoma Avenue, and Beloit Road. This section of the bypass is usually congested during rush hour because of traffic on I-894 and merging traffic from the Rock Freeway (I-43). This stretch usually has travel times between 10 and 15 minutes during the rush hour (as opposed to five minutes during non-rush-hour times). The Interstate turns eastward at the Hale Interchange in Hales Corners. US 45 turns westbound at that point to follow I-43 (Rock Freeway) south, and I-43 north follows I-894 to the east. The highway becomes the Airport Freeway and reenters Greenfield after the Hale Interchange. Generally, this section is referred
