Lancaster County has the most covered bridges in Pennsylvania with 29 covered bridges. Parke County, Indiana has the most covered bridges of any county in the United States with 31 covered bridges〔(【引用サイトリンク】year=2008 )〕 All of the covered bridges in Lancaster County, except for the Hunsecker's Mill Covered Bridge, Kurtz's Mill Covered Bridge, and the Willow Hill Covered Bridge, are listed on the National Register of Historic Places. Most have been on the list since 1980.〔(【引用サイトリンク】 work = National Register of Historic Places )〕 The WGCB numbering prefix for the county is 38-36 The bridges are an important tourist attraction, both economically and culturally. This is due to both their historical significance and, being in the heart of Pennsylvania Dutch country, the frequent, iconic Amish horse and buggies bridge crossings. They are often visited in the form of covered bridge driving tours. == History == In the early to late 1800s there were approximately 1,500 covered bridges in the state of Pennsylvania. That number has decreased to just over 200 bridges, with more located in Lancaster County than any other county in the state. The remaining covered bridges in the county are a remnant of a time where most bridges in the United States were made from wood, since wood was relatively inexpensive and easy to acquire. Bridge making, however, was anything but easy and required significant cost, effort, and time. The cost of the building the bridges was covered by government funds or by private individuals building bridges across their land. Since the bridges were built from wood, they were covered to provide protection from the weather, dramatically extending the life of the bridges. Nevertheless, as floods and fires destroyed more bridges, they were eventually replaced or bypassed with more durable and longer-lasting reinforced concrete and steel beam bridges. Most of the existing bridges are owned by the county government which is responsible for periodic upkeep and maintenance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of covered bridges in Lancaster County, Pennsylvania」の詳細全文を読む スポンサード リンク
