Removal and replacement of twin aging and undersized 6’ diameter corrugated metal culverts at the crossing of Bog Brook with a 40’ simple span bridge. Work also included stream bed restoration with strict oversight from Federal agencies due to the potential presence of Atlantic Salmon. Bog Brook’s crossing sits on a high‑use travel corridor relied on by residents, out‑of‑state visitors, and land‑management crews accessing the North Maine Woods making schedule a critical aspect of the job.
