Project Title & Location

- SR 240/I-182 to Richland Y – Add Lanes,

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.

Contractor/Consultant
ICON Materials, Kent, Washington

Recent Progress

The contract was advertised for bids on December 20, 2004,  and awarded to ICON Materials on February 23, 2005.

Design Construction Impacts

Site preparation activities will begin during the last week of March.  The contractor will place high visiblity construction fencing, start demolition of building structures located in the vicinity of the Richland Y Interchange, decommission existing utilities and start placement of eastbound roadway embankment.

Environmental Impacts / Compliance

Environmental staff identified native vegetation to be preserved within the wetland mitigation creation site, and coordinated with maintenance to remove Russian Olive from within the preserved vegetation boundary.

Environmental staff  facilitated the contaminated soil and groundwater issues along Columbia Park Trail.  This included meetings, conducting file reviews at Ecology, reviewing contractor work plans and reports, working with HQ Hazardous Materials staff and being on site during sampling.

Administrative projects include tracking progress of the Amon Creek Mitigation Project agreements and funding issues with Meadow Springs Country Club and WDFW, compiling the commitment tracking spreadsheet, developing Environmental Construction Manuals, preparing for environmental pre-construction meeting, and securing Northwest Archaeology as the cultural monitoring consultant.

Daily compliance monitoring will begin on March 28th with the start of construction.

Impacts to Traffic
Two lanes of traffic will be maintained in each direction during peak traffic times. It is likely there will be two total roadway closures, each 3 to 4 days, to reconstruct connections to ramps and bridges. Closures will be scheduled over weekends to reduce impacts to traffic. Detour routes will be maintained during these closures.
