Westbound I-84 traffic between the Centennial Way and Franklin Road interchanges will shift to new lanes on Saturday, Oct. 31. This change follows an earlier requirement for the right lane to exit at 10th Avenue beginning Wednesday, Oct. 28.
Why it matters
The project serves as a key logistical update for highway infrastructure in the Caldwell area, necessitating significant adjustments for daily commuters. Drivers must prepare for restricted access points and revised traffic routing during this transition.
Construction crews will execute ramp and lane closures nightly from 10 p.m. to 7 a.m. to facilitate the transition. These modifications affect access between the Centennial Way and Franklin Road interchanges.
The players
Idaho Transportation Department
This state government agency is responsible for the design, construction, and maintenance of Idaho's state transportation system.
The details
As part of the shift, the 10th Avenue westbound on-ramp and the Franklin Road westbound on-ramp are scheduled to close. Traffic in the right lane on westbound I-84 is required to exit at 10th Avenue to accommodate the ongoing work.
Timeline
The right lane requirement begins Wednesday, Oct. 28.
The traffic shift to new lanes occurs Saturday, Oct. 31.
Nightly ramp and lane closures occur from 10 p.m. to 7 a.m.
Market Landscape
This project aligns with the infrastructure expansion goals outlined in the Idaho Transportation Department's statewide long-range transportation plan. It represents a broader regional push to modernize highway throughput and safety standards across major transit corridors.
Commuters should expect delays and are encouraged to plan alternative routes due to the scheduled nighttime ramp closures. Access to the highway will be restricted, particularly at the 10th Avenue and Franklin Road on-ramps.
The takeaway
Drivers navigating westbound I-84 through Caldwell should prepare for significant changes to their typical transit routes. Monitoring local traffic alerts will be essential to avoiding congestion during the transition period.
