Project Title & Location
- SR 240/I-182 to Richland Y – Add Lanes, - SR 240/Richland Y to Columbia Center Interchange -Tri-Cities

Project Description
This project constructs additional lanes on SR 240 between Richland and Kennewick, linking Interstate 182 with the US Department of Energy's Hanford site, the Columbia Center commercial areas, and east Kennewick's industrial zones. The project will save travel time for auto and vanpool commuters and expand the bicycle corridor. There are currently four general purpose lanes; there will be six lanes when the project is completed.

Environmental Impacts / Compliance
The environmental staff is actively looking for additional mitigation credit resulting from unsuccessful attemps by the WDFW to complete negotiations for a stream enhancement project on Amon Creek. We have been working with WDFW, Ecology, the City of Richland and local conservation groups to find alternatives to meet our mitigation shortfall of approximately 3 acres. We have two potential options that we are looking to partner on. We have not yet completed this commitment. Sediment and erosion control BMP's are in place and performing effectively.

Impacts to Traffic
SR 240 lanes were closed between Thursday Dec. 1, 6:00 a.m. eastbound, 9:00 a.m. and reopened on Sunday, Dec. 4 at 10:30 a.m. allowing time for the contractor to construct Phase 1 traffic alignment tie-ins. Lane closures continued during non-peak hours for embankment haul and asphalt paving. During girder erection at the I-182 bridge, the interstate was closed between 11:00 p.m. and 5:30 a.m. with traffic routed through a signed detour. The same procedure was used at the SR 240/15 bridge when girders were placed over Columbia Park Trail at the Richland Y.
