Recent Progress
Geotech is completing the drilling for the bridges and retaining walls and will begin work on the Geotechnical Report. HQ Bridge has completed their preliminary bridge design and have begun the final design work. The Interchange Justification Report has been submitted for review and work continues on the Design Documentation Package. Design work has begun on the stage construction plans and work zone strategy.

Design Construction Impacts
Construction of the proposed retaining wall on the northeast side of the project, for SR240 westbound traffic, would require a right of entry permit from the US Army Corps of Engineers. Procurring the permit could take up to a year and would likely delay the ad date. We have moved the wall to an alternative location 10 feet away from the right of way line to eliminate the need for the right of entry. The project is moving along with no anticipated change to the ad date.

Environmental Impacts / Compliance
Environmental Documentation is on schedule for completion. Shoreline Management permit is required due a portion of the project within 200 feet of the Columbia River.

Impacts to Traffic
There were several lane closures during the drilling of the bore holes in areas adjacent to the existing road which resulted in minor impacts to traffic.
