Project Description: Pine Lake State Park has a popular beach area that is connected to its parking lot via a trail and tunnel under a county highway. This concrete box culvert is in good condition and will remain in place. However, the retaining walls and stone archway on both sides of the tunnel are in poor condition. This project will remove these retaining walls and archway and replace them with concrete retaining walls with stone veneer applied to the face of the concrete. The adjacent concrete walk and steps shall also be replaced to match the existing elevations.
