‘Taoyuan International Airport’ is a crucial gateway for people entering and leaving Taiwan. The landscape along the main connecting road, ‘National Highway No. 2,’ directly influences the primary impression left on domestic and international travelers passing through this section. The artwork needs to embody landmark and national gate imagery. To consider the emotions and feelings of inbound and outbound passengers, different images should be designed on both sides of the bridges to correspond to the mood transition of leaving and returning. These four overpass bridges are all located in Taoyuan County, so the artwork needs to consider the geographical and cultural characteristics of the local environment, such as the local flower industry, pond imagery, and green beautification.
