Porter Creek Bridge Replacement Project
NOE - Notice of Exemption
The project is limited to constructing the new bridge in such a way that the final alignment would be roughly centered on the existing bridge placement but would be wider to accommodate a center turn-lane. The replacement bridge is a single span concrete box girder bridge approximately 160-foot long with one 12-foot wide traffic lane in each direction of travel, a 12-foot wide left-turn channelization lane and two 10-foot wide shoulders. The center left-turn channelization lane would be used for vehicles accelerating onto Porter Creek Road from Franz Valley Road and residential driveways.
