石門和石門圩兩個村莊位于松陰溪兩岸。“石門圩”原來是石門村的農田，過去村民過河種田，后來慢慢就在河對岸建房建村，形成新的石門圩村。連接兩個村莊的石門大橋建于1974年6月，為無筋無肋混凝土雙曲拱橋，全長263米，該橋曾經是松陰溪南北交通的重要通道。2010年12月齋壇連接線橋建成貫通，石門大橋及王（村）齋（壇）線幾乎廢棄。由于年久失修且有安全隱患，當地政府一度考慮拆除這座大橋。

2016年松陰溪景區建設給這座大橋帶來了新的可能性。我們結合松陰溪沿岸綠道的游覽路線，提出保留石門大橋改造為步行廊橋和電瓶車觀光游覽停留點的策略， 提供了在松陰溪上觀其縱深的新視點：這段風景還包括了旁邊的千年古堰壩午羊堰，成為松陰溪景區的一個重要景觀節點。新建的廊橋也成為兩個村莊村口的共享公共空間，如同過去的風雨橋。

石門廊橋采用木裝配結構，外形借用當地建筑形態，和橋頭的石門驛站以及村莊的民居形成連貫性。廊橋沿著263米的大橋的展開，在橋拱處廊頂開放，呼應大橋的結構韻律，也形成線性路徑上光影交錯的節奏。橋中央放大的平臺，保留70年代建橋時的石刻欄板， 木裝配廊橋在這里斷開，空間驟然放大，視野開闊，平臺上的行列式綠樹繼續延續橋拱結構的韻律，也暗示到達松陰溪中的開放綠島。

石門廊橋作為一種指引，將人群引入周邊村落，不僅連接起松陰溪兩岸村莊，也進一步把人流量帶入到鄰近的村落里。 一公里外，王村的王景紀念堂以及周邊的村莊建設，和石門廊橋串點連線：廊橋所處的自然山水與王景紀念堂中的建筑歷史敘事，建構起這個區域獨特的 自然人文景觀。

The two villages on both banks of Songyin River, Shimen village and Shimen-yu village, were once one village. The name of Shimen-yu means farm land of Shimen. In ancient time, villagers of Shimen had to cross Songyin River to farm land and eventually they built houses on the other side and separated into a new Shimen-yu village.

With Wuyang Dam between two villages as the most ancient water dam in Songyang, this area became an important section for development of Songyin River Scenic District. An abandoned 260 meters long Shimen bridge right next to the Dam was again under discussion whether to be demolished: it was replaced by a new bridge in 2010 due to rapid increase of vehicle transportation and has been closed since then.

We proposed to convert the old Shimen bridge into a viewing platform for Songyi River and Wuyang Dam. A covered wooden structure with a pitched roof representing local buildings is introduced with openings to echo the structure rhythm of the existing bridge arch. This could serve as resting lounge for visitors as well as pedestrian connection for two villages. The wooden structure stops at the center to respond to the enlarged bridge platform with tree rows as a floating island on the river.

The new lounge bridge will also become a common public space uniting two villages once again. It could also be used in many different ways such as a weekend bridge market or for a holiday parade. Together with Wangjing Memorial and Wang village, this area will become an important culture and tourism node along Songyin River.
