Overview
ITD is proactively seeking to improve operations by building an eastbound auxiliary lane and shoulder. This is an additional lane on I-84 connecting the entrance and exit ramps of the Meridian and Eagle interchanges designed to facilitate smoother traffic flow by providing drivers with an opportunity to speed up or slow down in a space not used by high-speed through traffic.
Modifications to the single lane on-ramp at the Meridian Road Interchange and the single lane off -ramp at the Eagle Road Interchange will convert them to two-lane entrance and exit ramps to be compatible with the new eastbound auxiliary lane.

Background
Continued development, growth, and traffic have strained I-84 during the morning commute. The on-ramp from the Meridian Road Interchange to eastbound I-84 has significant congestion during the commute and highway users accessing I-84 often back up onto Meridian Road. The Eagle Road Interchange eastbound off-ramp has similar congestion issues during the morning commute, including at the intersection with Eagle Road. This causes vehicles to back up along the ramp and sometimes onto I-84. The congestion slows traffic and causes safety concerns. This project was developed to address these concerns.
Typical section
The design will add a new 12-foot-wide auxiliary lane and 10-foot-wide shoulder to the eastbound lanes of I-84.
Retaining walls will be provided along the corridor, as needed, to reduce impacts to adjacent property and keep the improvements within the existing right of way.

Lane shifts during construction
Construction activities are anticipated to begin in 2031. During construction, all four lanes of eastbound I-84 will remain open during daylight and heavy traffic volume hours. These lanes will be shifted between Meridian Road and S. Locust Grove Road toward the median. A barrier between traffic and the work area will be added to provide adequate safe space for auxiliary lane and shoulder work. The construction work zone will be separated from traffic by temporary concrete barriers.
There will be some overnight lane closures and detours to remove and replace sign structures along I-84 and perform other activities where extra room is needed.
The eastbound Meridian Interchange on-ramp and Eagle Interchange off-ramp will remain open at all times. Limited ramp closures during non-peak traffic times may be necessary for construction activities.
