About this file
This document is a Coring Plan for Bridge BR 08306, specifically the New Youngs Bridge located on US101 (Highway 009) at Milepost 4.91, prepared for the Oregon Department of Transportation (ODOT). The plan details a comprehensive core sampling strategy for the bridge, requiring 16 total cores to be extracted across the bridge deck, with specific instructions for core placement, including one core in the wheel rut for every 10,000 square feet, not exceeding 12 cores total. The cores are to be 4 inches in minimum diameter and at least 4.5 inches long, with a maximum coring depth of 5 inches.
The bridge, built in 1964, has a deck measuring 4,208 feet in length, 35 feet in width, and 6-7 inches in depth, with a total surface area of 147,280 square feet and no previous overlays. The coring plan provides precise locations for 16 core samples, with recommendations to take cores near drains, old core locations, and to log the actual extraction points. Each core will be labeled with the bridge number and a specific core number. The geographical coordinates for the coring site are 46.176180, -123.868472, and the plan includes detailed span measurements and previous coring locations near bent #20 and bent #30.
