{"product_id":"pittsburghs-bridges-9781531678289","title":"Pittsburgh's Bridges","description":"Pittsburgh is the \"City of Bridges,\" and what remarkable bridges they are  The area's challenging topography of deep ravines and mighty rivers--the Monongahela, Allegheny, and Ohio--set the stage for engineers, architects, and contractors to conquer the terrain with a variety of distinctive spans. Many were designed to be beautiful as well as functional. While other cities may have one signature bridge, Pittsburgh has such a wide variety that no single bridge can represent it. Pittsburgh's Bridges takes a comprehensive look at the design, construction, and, sometimes, demolition of the bridges that shaped Pittsburgh, ranging from the covered bridges of yesterday to those that define the skyline today.\u003cbr\u003e","brand":"Arcadia Publishing Library Editions","offers":[{"title":"Default Title","offer_id":50492790341906,"sku":"9781531678289","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_f0037eb6-3d45-4961-ba8f-2fc89c9950c3.jpg?v=1737214806","url":"https:\/\/surprise-castle.myshopify.com\/products\/pittsburghs-bridges-9781531678289","provider":"Surprise Castle","version":"1.0","type":"link"}
