Expanded Lanes On I-84 Near Nampa Could Soon Become Reality

Jun 8, 2018

Traffic on Canyon County’s main highway could get a little bit lighter in the near future.

This week, the U.S. Department of Transportation announced I-84 could soon be widened to three lanes in the Nampa area. The project is a finalist for a $90 million federal grant that’s undergoing Congressional review.

If approved, lanes would be expanded along nearly three miles of I-84 between Franklin Road and the Karcher Road underpass. Interchanges along the way would also be improved.

More than 80,000 vehicles travel in both directions on that area of the freeway on an average weekday and it can get congested at times.

State and local governments would have to chip in about $60 million to help fund the project.

According to the Idaho Statesman, the Idaho Transportation Department spent hundreds of millions of dollars widening I-84 from Boise to the western border of Nampa between 2007 and 2015.

Congress has 60 days to sign off on the grant.
