The Governor Thomas Johnson Bridge (also referred to as the Thomas Johnson Bridge and the Solomons Bridge) is a bridge in Maryland over the lower Patuxent River joining Calvert and St. Mary’s counties. The bridge, named for the first governor of Maryland, Thomas Johnson, was built in 1977, and officially opened in January 1978.〔(【引用サイトリンク】title=Development of Our Roadways )〕 The bridge, carrying Maryland Route 4 (MD 4), is one of two crossings of the Patuxent River in Southern Maryland (the other is the Benedict Bridge approximately 20 miles up river, where MD 231 connects Calvert County and Charles County). The north end of the bridge, on the Calvert side, is located in Solomons. Just prior to the bridge, MD 2-4 narrows from four lanes to two, and MD 2 exits the highway, passing under the bridge and heading toward downtown Solomons. MD 4 continues onto the bridge itself and over the Patuxent River. ==Description== The bridge, carrying two lanes and no shoulders, rises to a height of approximately tall, making a trip over the bridge in windy weather somewhat nerve-wracking for travelers. From the top of the bridge, one can see the entire town of Solomons, the runways at the Patuxent River Naval Air Station, and the Chesapeake Bay. The bridge begins in St. Mary's County, before even reaching the Patuxent River. It passes over Town Creek first, then crosses over the unincorporated community of Spencers Wharf on a viaduct. Once over the community, the bridge passes over the Patuxent River, entering Calvert County. Shortly after reaching land, MD 2 joins MD 4 and cross Calvert County together for a long concurrency on a four-lane divided highway. The Thomas Johnson Bridge itself can be categorized as both a beam bridge and an arch bridge. Massive concrete pilings hold the bridge up over the river. 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「Governor Thomas Johnson Bridge」の詳細全文を読む スポンサード リンク
