Kirker Pass northbound Truck Climbing Lane Project No. 0662-6R4052, CP #15-04

The Contra Costa County Public Works Department (PWD) proposes to provide a truck climbing lane along Kirker Pass Road between Clearbrook Drive in the City of Concord and the northernmost Hess Road intersection. Kirker Pass Road is a four-lane principal arterial and route of regional significance between Central and East Contra Costa County. The roadway connects the City of Concord on the southwest end, through the Meridian Hills, to the City of Pittsburg on the northeast end. The purpose of the project is to provide a northbound truck climbing lane and paved shoulders for future Class II bike lanes. The project is needed to improve safety for motorists and bicyclists along this stretch of road. The road is frequently used by commuters and has heavy truck traffic. with sustained grades steeper than 8 percent, trucks are unable to match the speed of other vehicles on the roadway, causing significant congestion and creating a safety hazard. project elements will include roadway widening for the truck climbing lane, paved shoulders for future Class II bike lanes, relocation of drainage features, retaining wall construction; installation of signage and striping; construction of two bioretention areas; roadway conforms due to change in grade; and relocation of other existing roadside features. An open grade asphalt concrete (OG AC) overlay will be placed on the southbound and northbound lanes as part of the project, within the project limits. Standard construction equipment will be used, including but not limited to: excavators, graders, scrapers, loaders, sweepers/scrubbers, plate compactors, rollers, backhoes, cranes, drill rigs, and pavers. Disturbed areas will be stabilized following construction to ensure appropriate erosion and sediment control. Construction activities will generally be limited to the hours between 7:00 a.m. to 5:00 p.m. with noise-generating activities focused between 8:00 a.m. to 5:00 p.m.; however, there will be limited night work as necessary. Construction is expected to begin in 2018 and may require two construction seasons. Real Property transactions, including right-of-way acquisition may be necessary in support of this project. General Plan Conformance may be necessary from the City of Concord.
