Title

Mineral King Bridge (Historic Oak Grove Bridge) Replacement Project

Description

The purpose of the Project is to construct a replacement bridge on a new alignment. The new replacement bridge would be constructed immediately east (approximately 50 feet upstream) of the existing bridge to preserve views from the approach roadway. The replacement bridge would consist of an approximately 100-foot-long clear span steel plate girder bridge the same width as the existing bridge, approximately 19 feet wide from curb to curb. The total bridge width, with barrier rails, would be 23 feet (including a 19-foot travel way plus two 2-foot barrier rails). The new alignment would require cutting into the existing hillside at both bridge approaches as well as the construction of rock anchor retaining walls. The existing bridge will be rehabilitated and be used for non-vehicular usage by pedestrians, cyclists, etc. There are three potential staging areas being considered for the Project.
