Narrative Description Of Your Entry: 

The Town of Hillsborough’s 2017 El Cerrito/Crystal Springs Roadway Rehabilitation Project consisted of overlaying the existing roadways with Rubberized Asphalt Concrete (RAC). El Cerrito Avenue and Crystal Springs Road are two primary scenic thoroughfares in Town for both vehicular and bicycle traffic. The Town recognized the benefit of RAC Overlay on these roadways as compared to the traditional Asphalt Concrete Overlay for the improvement to the driving experience by creating a quieter and smoother ride, including for bicyclists; and for promoting the use of recycled construction materials. This project utilized a total weight of 156,762 pounds of crumb rubber, diverting approximately 13,000 Passenger Tire Equivalents. The Town received grant funding from Cal Recycle for the use of RAC, awarding the Town the differential cost of AC to RAC Overlay for the 12,000 linear feet project. In addition to the resurfacing, thermoplastic bicycle “sharrows” were placed to encourage multi-modal transportation routes. Within Town of Hillsborough’s City Limits, Crystal Springs Road is a Class III Bicycle Route as identified by The San Mateo County Comprehensive Bicycle and Pedestrian Plan. It connects a Class II Bike Lane from San Mateo down to El Camino Real. This particular roadway provides connectivity to cyclists traveling east/west from several Peninsula cities to the Sawyer Camp Trail, which is the busiest multi-use trail in the Peninsula with 300,000 visitors every year. The project improvements have assisted in promoting East to West multi-modal travel in an area where bicycle pathways are otherwise limited. The project was completed on schedule in August 2017 and has increased the PCI’s of these segments from as low as 66 to up to 100, successfully renewing the life of the pavement and improving public safety for all modes of transportation.
