Document Description
The proposed project would replace the existing single-lane bridge with a new two-lane bridge and widened roadway approaches. The new bridge would be approximately 147 feet long and 27 feet wide, which would be 27 feet longer and 9 feet wider than the existing bridge. The horizontal alignment of the new bridge would match that of the existing bridge, which is approximately perpendicular to the normal stream alignment of Mill Creek. The new bridge would be similar in character to the existing bridge, namely a single-span , steel truss structure. In addition to the new bridge, approximately 200-foot section of the eastern roadway approach and 300 feet of the western approach prior to the bridge would be improved with two 10-foot wide travel lanes with 2-foot wide shoulders to accommodate the new bridge deck elevation, width and location.
