This project improves connections to the interstate and encourages economic growth and development for both Union Gap and Yakima. The interchange reconfiguration will provide increased motorist safety, additional capacity, and help free up movement on and off the interstate to connect smoothly with the expanding local road system.

Recent Progress
A surveying consultant is currently surveying the project to show the anticipated right-of-way impacts the project will require. Access plans are currently being worked on to prepare for the design/access hearing, which is scheduled for late winter/ early spring of 2008. Individual meetings are being scheduled to update adjacent property owners on the project.

Design Construction Impacts
Early comments from resource agencies center on impacting the floodplain and fully allowing possible future flood waters to flow through the new interchange. This risk cannot be quantified until the discipline reports and consultations with resource agencies are complete. To improve Level of Service (LOS) a loop ramp for the westbound on-ramp was added to the roundabout alternative. This addition required the design team to evaluate the replacement of the I-82 mainline bridges for vertical clearance. Preliminary results of this evaluation show the need to adjust the I-82 profile. Although these additions will increase the cost of the roundabout alternative the total project cost is within budget at this time.
