It carries U.S. Highway 58 and operated without tolls until February 1, 2014. == History == The two-lane Midtown Tunnel was completed September 6, 1962, supplementing the Downtown Tunnel and the Berkley Bridge. It was the second fixed crossing directly between Portsmouth and Norfolk across the Elizabeth River. It was financed and built by the Elizabeth River Tunnel Commission with toll revenue bonds. In 1988 and 1989, during an expansion of I-264, the Downtown Tunnel and the Berkley Bridge were rebuilt and expanded. Tolls were also removed from the Midtown and Downtown tunnels at that time. Prior to 2007, the westbound lane of US Route 58, right before the tunnel's entry, had an HOV lane that spanned a total of 25 yards. Until its removal during construction in 2007, this lane allowed HOV traffic to merge in right at the tunnel entrance. There is some speculation that this might have been the shortest HOV lane in the United States, and possibly the world. 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「Midtown Tunnel (Virginia)」の詳細全文を読む スポンサード リンク
