Attachment 001 Boring Location Map.pdf

This file is a Boring Location Map attachment for a federal highway project. The map depicts the Winchester Creek Bridge Replacement project located in Douglas County, Oregon, under Project No. OR FLAP DOUGLAS 251(2), managed by the Western Federal Lands Highway Division based in Vancouver, Washington. The aerial image shows the bridge location relative to Winchester Creek, with two boring locations marked as BH26-01 and BH26-02, positioned along the roadway and near the waterway to facilitate geotechnical investigation. The map was prepared in August 2026 and includes a scale bar in feet (0-67-134 feet) and a compass rose for orientation. This attachment serves as a reference document for identifying subsurface sampling locations during the bridge replacement design and planning phase.
