Expansion and Safety Projects


Road expansion (new road construction or added travel lanes) and safety projects require the preparation of detailed design plans.  These projects are more expensive than road maintenance and surface treatment projects and often require the County to leverage State or federal funding to offset the design and/or construction costs.  When federal funding is utilized, the project development process takes much more time due to the additional requirements and approvals that must be met with the expenditure of federal funding.  The list below highlights the road expansion and safety projects that are already in or will soon be in the project development process.
