Sustainable Practices for Road Tunnels
Tunnels are integral to the system of public roads and are vital to increase mobility and benefit the economy. The harsh tunnel environment accelerates the rate of corrosion and deterioration. Structural, civil, and functional systems are vulnerable to these aggressive degradation processes; this is especially true as tunnels age and their service lives are extended. When tunnels are closed to traffic, vehicles must detour along less efficient routes; and communities must bear significant social, economic, and environmental costs because of increased gridlock, noise, and vehicle emissions. Over prolonged periods, the cost of goods and service may also increase. Tunnels represent a sizable investment; and significant resources are needed to maintain tunnels in a safe condition and to provide reliable levels of service. Tunnel owners have limited resources; and cost-effective decisions must be made to ensure long-term viability. Tunnels that are not maintained adequately are more prone to extensive and costly repairs. Effective tunnel management practices make use of data-driven, risk-based analyses to evaluate life cycle costs, prioritize repairs to tunnel system, and preserve the levels of safety and reliability within the tunnel. Sustainability is achieved by the implementing a comprehensive management approach that optimizes tunnel operations, maintenance, inspection and evaluation.
