Frontage Road , Oakland 2023

Cooper Construction and Engineering was commissioned to install road bollards on this roadway to delineate the perimeter or circumference of the island. These plastic bollards offer several advantages in this context:

  1. Clear Boundary: The bollards serve as a clear boundary marker, defining the limits of the island and preventing vehicles from encroaching onto it.

  2. Traffic Guidance: They help guide traffic around the island, ensuring drivers maintain a safe distance and follow the designated path.

  3. Enhanced Safety: By clearly indicating the island's boundaries, the bollards enhance safety for both motorists and pedestrians, reducing the risk of accidents and collisions.

  4. Improved Visibility: The high visibility of plastic bollards makes them easily noticeable, even in low-light conditions or adverse weather, further enhancing road safety.

  5. Traffic Calming: Bollards can act as traffic calming measures, encouraging drivers to slow down and navigate the area more cautiously.

  6. Aesthetic Appeal: Plastic bollards are available in various colors and designs, allowing for customization that complements the aesthetics of the island and surrounding area.

  7. Cost-Effective: Plastic bollards offer a cost-effective solution for marking island perimeters and traffic control when compared to traditional materials.

  8. Durability: These bollards are durable and capable of withstanding harsh weather conditions, making them a reliable, long-term solution.

Cooper Construction and Engineering's installation of plastic bollards to mark the island's circumference demonstrates our commitment to providing effective and efficient solutions for road safety, traffic management, and the clear delineation of roadway features.
