After delays to coordinate with patches on the upper couplet and the discovery of a surprisingly large rock, construction of the new culvert on the lower couplet is complete. Notice how deep the concrete culvert frame is and then how little is exposed above the water in the last picture. The bottom is filled with natural stream bed material so fish can pass through easily.
Crews discovered a very large boulder that needed to be removed to install the culvert.
