Document Description
The purpose of this project is to improve bicyclist safety by widening the roadway shoulder on a 200-foot segment of Livorna Road as identified in the Contra Costa County Transportation Authority's Countywide Bicycle and Pedestrian Improvement Plan. The project will widen the southern shoulder of the road segment to a uniform 5-foot shoulder for bicyclist travel, completing the bicycle accessibility from I-680 to the County boundary directly west of Serafix Road. The construction process for this project will include clearing and grubbing, roadway excavation, and aggregate base and hot mix asphalt pouring. Drainage modifications may be needed to conform the asphalt to the storm drain inlet. Ground disturbance and excavations up to 2 feet are anticipated. Appropriate best management practices for stormwater control (i.e. storm drain inlet protection) will be in place. Temporary traffic controls will be implemented during construction activities; emergency vehicles will have access at all times. Construction will take approximately 2 weeks to complete.
