中国大学最长的桥—川大长桥。418米,桥的设计者川大校友,为纪念大学初恋女友。毕业她出国了,没有承诺。多年之后她已嫁人,他也为人夫父。长桥的设计只为纪念他大学时纯真遗憾的爱情。桥上418块砖刻着英文字母,是她曾念给他的情诗《whenyouareold》 WHEN you are old and gray and full of sleep. And nodding by the fire, take down this book. And slowly read, and dream of the soft look Your eyes had once, and of their shadows deep; How many loved your moments of glad grace. And loved your beauty with love false or true; But one man loved the pilgrim soul in you, And loved the sorrows of our changing face. And bending down beside the glowing bars, Murmur, a little sadly, how love fled And paced upon the mountains over head,And had his face amid acrow do face stars.
