Project Facts

Project Number: A010(939)
Key Number: 10939
MP 43.58-44.68

The Idaho Transportation Department will replace the interchange at I-84 and Meridian Road. The new interchange will reduce congestion, improve safety and make way for a fourth lane on I-84.

The interchange design is a Single-Point Urban Interchange(SPUI) similar to the Vista Avenue in Boise and Ten Mile Road in Meridian. The new design for the interchange will include:

Three through lanes in each direction on Meridian Road.
Widening I-84 to four lanes in each direction underneath the interchange.
Dual left-turn lanes on Meridian Road for each I-84 on-ramp.
Curb, gutter, sidewalks and bicycle lanes on Meridian Road.

In addition to the Meridian Road Interchange reconstruction, ITD will be replacing the Broadway Avanue Interchange and Gowen Road Interchange in Boise. For more information, click here.

Background

The current interchange at I-84 and Meridian Road was built in 1965. Since that time, interchange traffic has increased from 15,000 to 128,000 vehicles per day.

In 2008, ITD completed and environmental study of I-84 between Karcher Road in Nampa and Five Mile Road in Boise. The study recommended widening the interstate to four lanes in both directions between Garrity and Meridian interchanges. Many of the bridges over I-84 were replaced to accomodate additional lanes underneath. Replacing the Meridian Interchange will allow ITD to finish widening I-84.
