Structural specifications

The Sky Gate Bridge is a continuous truss bridge that measures 3.75 km (2.33 mi) long, 29.5 m (96 ft 9 in) wide (6 lanes), and 25 m (82 ft) at its highest point in the center.[1][4]

History

The bridge commenced construction in June 1987, and was completed in March 1994.[1] On 21 April 2009, management of the expressway portion of the bridge was handed over to the West Nippon Expressway Company.[3] This expressway was numbered E71 alongside the Kansai-Kūkō Expressway in 2016.[5]

Typhoon Jebi

The bridge was damaged on 4 September 2018 by Typhoon Jebi. A 2600-ton tanker lost power and was blown into one side, severely damaging half of the automobile lanes and the rail lines.[6] The bridge, being the sole link between the airport and the mainland, stranded approximately 3000 passengers and 2000 staff[7] overnight at the airport. They were evacuated the next day via the Kōbe–Kankū Bay Shuttle (神戸-関空ベイ・シャトル) ferry to nearby Kobe Airport,[8] later joined by buses over the undamaged half of the bridge.[7] The bridge was partially reopened to vehicle traffic on 7 March 2019 with four lanes open.[9] The bridge's full capacity with six lanes of traffic was restored on 8 April 2019.[10]

Junction list

The entire expressway is in Osaka Prefecture. The sequence of kilometer posts continue from the Kansai-Kūkō Expressway.
