US 12/SR 124 to McNary Pool – Add Lanes –
Tri-Cities (Phase 2)     MP 295.2 to MP 299.3

Contractor/Consultant
 Steelman-Duff, Inc.  

Recent Progress

The Contractor began work on January 3, 2005.   The Contractor and WSDOT forces worked diligently on the project for months, building approximately 10 lane-miles of new roadway.  On May 31, 2005 the two new US 12 eastbound lanes were opened to traffic.  Work continued through June constructing intersection channelization and resurfacing the existing pavement on the (now) westbound US 12 lanes.

Progress slowed through the months of July and August due to the Contractor being heavily committed to work on other projects, and contract requirements that seeding operations not be done until October.  Work resumed, in earnest, around the end of August.  The new signals were in place and functioning by September 14, 2005.

It is anticipated that Physical Completion will be attained by October 21, 2005, which is right on the original schedule.  It is anticipated that we will be within the original budget of $7,203,785.39.

Design Construction Impacts

Minor cost overruns, based upon quantity variations, are anticipated.  The predicted additional costs will be covered by the contingency funding.

Environmental Impacts / Compliance

An Environmental Assessment, a Section 106 study and a noise study were completed.  There were no adverse impacts created by this project. 

The US Army Corps of Engineers has confirmed that the "Talent Ruling" will not affect this project.  

A National Pollution Discharge Elimination System permit has been acquired for construction of this project.

Regional Construction staff, with support from Regional Environmental staff, continue to work with Contractor personnel to ensure compliance.

Impacts to Traffic

WSDOT, WSP, and Steelman-Duff have worked with local businesses and schools, to minimize traffic impacts by adjusting work activities during peak hours.   One lane of traffic in each direction will be maintained at all times during construction.    All parties continue to communicate and work together to minimize disruptions to the traveling public and to provide a work zone that is as safe as possible.
