What is the world's longest straight road without any corners or bends going from point a to point b directly?

The world's longest road without bends is in Saudi Arabia, the road connects Harad area with Badha on the UAE boarder. The road is about 260 km, 160 miles, and at night you can see cars coming on the opposite direction from very far distance. But when you drive, watch for camels that cross the road. See the link to it.

Or is it this one?

Australia - The "90 Mile Straight" nearly 1,000km to the east of Perth on the Nullabor Plain, Australia. This road is 90 miles or 146km long and while it goes up or down a bit, following the contours of the land, it does so without any bend, kink or deviation.

And

The record for the longest straight section of railway in the world (478 km) is the Trans-Australian Railway, upon which runs the Indian-Pacific passenger train that crosses the Nullarbor from Perth to Sydney via Adelaide.
