By Friday November 11 the new bridge was installed over Pierce Creek and the road bed was filled and rebuilt. Guard rails were added to the bridge and the water was turned back into Pierce Creek. Here are some photos:
When Pierce Creek was temporarily dewatered for a few days the Forest Service biologist checked for fish in the section of stream below the culvert and he found 50 rainbow trout. This is good news because it shows at least below the culvert and to the South Fork Boise River that Pierce Creek has been serving as rearing habitat.
The stream under the bridge is four feet lower in elevation than the invert (bottom) of the culvert that was previously in place. Pierce Creek is a high gradient stream, especially in the section from its mouth to the road. The culvert interrupted the normal channel characteristics and elevated the stream bottom. In fact, when excavating the culvert an 18-inch metal culvert was found plugged and buried beneath the 48-inch pipe.
