Project Facts

MP 41.5-42.5
Project Number: A009(815)
Key Number: 09815

The Idaho Transportation Department (ITD) has constructed a new I-84 interchange at Ten Mile Road in Meridian. The new interchange opened to traffic in May 2011. The project will relieve congestion at the existing I-84 Meridian Road Interchange and improve access to the growing area west of Meridian Road.

Background:

ITD and the Community Planning Association of Southwest Idaho identified Ten Mile Road as the highest priority for a new interchange in the 2001 I-84 Corridor Study. The study recommended increasing interstate access between Caldwell and Meridian.

Description:

This project included a new interchange at Ten Mile Road and several improvements to the surrounding roadways. Improvements include:

New I-84 on- and off-ramps at Ten Mile Road.
Extending Tasa Drive to Overland Road with an underpass at Ten Mile Road.
Widening Ten Mile Road from two to four lanes between Overland and Franklin roads.
Building an underpass and intersection on Ten Mile Road for future local roads north of I-84.

The new interchange is a Single Point Urban Interchange (SPUI). A SPUI has one traffic signal at the center that allows for protected left turns in each direction. Click here to download a map and driving directions.
