Varina-Enon Bridge carries Interstate 295 across the James River near Dutch Gap between Henrico County near Richmond and Chesterfield County near Hopewell, Virginia. It was opened to traffic in July 1990. The Varina-Enon Bridge has six lanes (three lanes each way) with full right and left shoulders, and is a cable-stayed bridge with 150 feet (46 m) of vertical navigational clearance and 630 feet (192 m) of horizontal navigational clearance. The bridge spans the shipping channel that leads to the Port of Richmond. The overall bridge length is 4,680 feet (1426 m). The bridge is owned and maintained by the Virginia Department of Transportation (VDOT). It was named for Varina, the original county seat of Henrico County which was located near the north end, and Enon, a small community near the south end in Chesterfield County. This bridge was also affected by the 1993 tornado that destroyed half of the Historic District of Petersburg, Virginia, a Wal-Mart in nearby Colonial Heights, and portions of the city of Hopewell. == Concrete cable-stayed bridge: a new design == The replacement bridge for the Sunshine Skyway across Tampa Bay south of St. Petersburg, Florida, was completed in 1988 and was the first major concrete cable-stayed bridge project in the United States. The Varina-Enon Bridge became the second. The design was selected because a high level was needed to clear a shipping channel, but there was a strong desire to avoid a drawbridge configuration following the collision of the SS ''Marine Floridian'' into the Benjamin Harrison Bridge at Jordan Point, a few miles downstream, in 1977. That complex bridge structure was out of service for over a year. At 157 feet (48 m) tall, the Varina-Enon Bridge is the second tallest bridge in Virginia after the Wilson Creek Bridge at 175 feet (53 m) which carries the Virginia Smart Road over Wilson Creek in Montgomery County. 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「Varina-Enon Bridge」の詳細全文を読む スポンサード リンク
