Project Title & Location

Attalia Vicinity – Add Lanes – Tri-Cities

(Phase 3)

MP 302.14 to MP 305.49

Project Description
Attalia Vicinity is the third phase of five phases that will reconstruct US 12 as a four lane divided highway from SR 124 to the Walla Walla River, and develop a plan for future four-laning from Wallula to Walla Walla.

Contractor/Consultant
 Project not yet advertised or awarded. 

Recent Progress
Design work continues on the project.  Design of the railroad bridge is underway.  The Findings and Order package was published on March 10, 2005 and is out for the required 30-day review period.

Design Construction Impacts

The ending point for this project has been changed slightly.  The new end point and lane configuration will better accommodate any possible rerouting of US 12 if determined necessary by the ongoing Phase 4 Planning Study.  At the same time, this change will provide for a safer operation of Boise Cascade's main entrance and minimize impacts and improve safety at their trucking facility.

Early estimates indicate that the design and construction of this project will be over budget.  The exact amount is currently being determined.  A change from the initial alignment and the construction of frontage roads account for some of the cost increase.  Under-estimating of a few bid items along with an increase in construction costs accounts for the balance of the increase.

Environmental Impacts / Compliance

There are no environmental impacts anticipated that would affect the delivery date.  The Environmental Assessment is being updated to evaluate project specific areas not covered in the original report.

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

Impacts to Traffic

We anticipate limited one-lane closures and brief delays to allow for the contractors'  truck operations during the construction phase.
