Technological Advancements - Innovative construction techniques and smart technologies are being employed in bridge and road projects to ensure safety and efficiency, such as the use of intelligent sensors in bridge construction [12][13]. - The implementation of a heating system in high-altitude roads aims to improve winter travel safety by quickly melting snow [13]. Environmental Considerations - Sichuan's transportation projects prioritize ecological protection, with measures taken to minimize the impact on wildlife habitats and promote environmental sustainability [13][14]. Tourism Integration - The development of transportation infrastructure is closely linked to tourism, with new highways connecting major tourist attractions, enhancing accessibility and promoting regional tourism [14].
