The Idaho Transportation Department is designing improvements to Interstate 84 between Caldwell and Nampa. This project is necessary to improve safety and mobility on I-84 in Canyon County. The existing interstate can no longer accommodate current traffic volumes at peak periods of the day. As the Treasure Valley continues to grow, congestion in this corridor will increase.
The planned improvements include:
In addition, ITD completed an environmental evaluation to help determine the needed improvements that will benefit long-term safety and capacity on the corridor while minimizing impacts to the environment and adjacent properties
The environmental evaluation included field work, analysis, surveying and mapping, environmental research and reports, geological reconnaissance and materials report, preliminary hydraulic assessments, roadway drainage analysis and public involvement.

Community input will play an important role in shaping the long-range plan for I-84 in Canyon County. Please watch for more information on a Public Meeting. To request text or email updates about this project, text 84CORRIDOR to 47177.
