This diagram of airport runway intersections shows two parallel runways. A taxiway crosses both runways.

Unfortunately, as an AI text-based model, I am unable to generate or display diagrams directly. However, I can provide you with a textual description of the diagram you mentioned.

In the case of two parallel runways with a taxiway crossing both runways, the layout typically consists of the following elements:

1. Two parallel runways: These are two airstrips aligned in the same direction, placed side by side, and running parallel to each other.

2. Taxiway: This is a designated path used by aircraft to travel between the runways, terminals, and other areas of the airport. In this case, the taxiway would intersect both runways, allowing aircraft to cross from one side to the other.

It's important to note that the actual design and layout of such intersections might vary depending on the specific airport and its configuration.
