The construction and installation work for the oil pipeline branch to the Komsomolsk Refinery involved building a route road, access roads to oil spill response sites, and four overpasses over the Selgon, Kharpi, Alkan, and Khevchen rivers. The overpasses have improved the transportation accessibility of the branch pipeline, especially in the off-season, while also raising the safety levels of its operation, maintenance, repair, and protection.
