The Idaho Transportation Department is conducting a traffic study and environmental analysis of I84 between Caldwell and the Karcher Interchange in Nampa. Improvements are needed because this stretch of interstate can no longer accommodate current traffic volumes at peak periods of the day.

A preliminary traffic analysis estimates traffic east of the Franklin Road interchange in Caldwell will increase by over 60% by 2040.

Safety

Rear-end crashes are the most prevalent type of crash and represent 30% of all crashes within the study area. Contributing factors for rear-end crashes include unexpected lane changes and unexpected stops, which are often associated with congestion.

Traffic study

The traffic study helps ITD confirm today’s traffic volumes and estimate future traffic volumes on the interstate. The results will help identify interstate improvements and determine how far west into Caldwell improvements vare needed.

Environmental evaluation

In compliance with the National Environmental Policy Act (NEPA), the environmental evaluation provides an environmental document and clearance for addressing the traffic needs on the interstate. The document evaluates potential improvements that will improve long-term mobility while minimizing impacts to the human and natural environment. The evaluation will consider potential impacts to adjacent properties, minority and low-income populations, noise, floodplains, wetlands, air quality and many other factors. Public input is an important part of the environmental study. Several opportunities to provide input and help identify improvements will be provide throughout the study process.

Schedule & Funding

ITD has allocated $193 million to complete the environmental study, traffic analysis, preliminary design and construction of projects on I-84 between Caldwell and the Karcher Interchange in Nampa. If ITD is granted environmental clearance quickly, design and construction could begin as early as 2020.
