Title

Porter Creek Bridge Replacement Project

Description

The proposed project would replace the Porter Creek Road Bridge over Porter Creek, located on Porter Creek Road near the intersection of Franz Valley Road, in the Mark West Springs area. The bridge is 158 feet long and 28 feet wide and has four spans across Porter Creek. The proposed replacement bridge is a two-span concrete box girder bridge that would be approximately 160-feet long with two twelve-foot travel lanes and a twelve foot wide center-turn lane, and two 10-foot wide shoulders. The traveled width of the bridge would be 56-feet. The bridge would be built in two stages with the first stage consisting of one-lane bridges built upstream and downstream of the existing bridge. The second stage would be to remove the existing bridge and build a fill-in bridge between the two one-lane bridges. In this way, uninterrupted two-way flow of traffic through the construction zone would be maintained.
