Structural specifications
The Sky Gate Bridge is a continuous truss bridge that measures 3,750 meters long, 29.5 meters wide (6 lanes), and 25 meters at its highest point in the center.

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

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. The bridge, being the sole link between the airport and the mainland, stranded approximately  passengers and  staff overnight at the airport. They were evacuated the next day via the  ferry to nearby Kobe Airport, later joined by buses over the undamaged half of the bridge.
The bridge was partially reopened to vehicle traffic on 7 March 2019 with four lanes open. The bridge's full capacity with six lanes of traffic was restored on 8 April 2019.

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