The Patterson Pass Road Safety Improvement Project is intended to improve roadway safety along an approx. 1300 feet section of that road, approx. 7 miles east of Livermore. It would reconstruct both lanes and widen the roadway and shoulder adjacent to the eastbound lane approximately 8 feet. The project would include the following components: (1) removing and relocating an existing barbed wire fence approximately 20 feet to the south; (2) placing and compacting soil fill with a 2:1 slope leading from the new gravel shoulder; (3) excavating and reconstructing the road shoulder; (4) placing and compacting aggregate base for the new road section; (5) placing and compacting new asphalt concrete surfacing, (6) placing an aggregate base layer along the road shoulder; and (7) installing a 400 foot long metal guard rail between MP 6.50 and MP 6.58.
