The
Interstate 184 journey
At just 3.62
miles, Interstate 184 is the shortest interstate in Idaho. Technically a spur
route of I-84, it is the only three-digit in the state. It serves as a primary
commuter route carrying traffic from I-84 into downtown Boise. The western terminus
is known as the Flying Wye near the Maple Grove Road overpass. The eastern terminus
is co-signed with U.S. Highway 20 and U.S. Highway 26, known locally as Broadway
Avenue.
During the
1970s, the interstate was known as I-189N (I-84 was then known as I-80N) and
was the only three-digit interstate in the nation to have a directional suffix.
Often referred
to as "the connector," I-184 has appeared in planning maps since the
1960s. After I-84 was commissioned and signed in 1980, I-184 in Boise was signed
as Business Loop I-84. This designation was eliminated in favor of I-184 by
the late 1980s or early 1990s. The business route signage is no longer present
along this route.
The Boise
West Connector was dedicated on Dec. 12, 1968. The last major construction project
– the WYE Stage II – was completed in 2004 adding new lanes, on-ramps
and off-ramps and a flyover bridge.
