I went down to the Barapullah Nala (drain) to photograph the progress of the elevated road, and found the nala in spate because of today's heavy rains. Here are a few photos.
The first photo is of the nala at the railway line near Nizamuddin Railway Station. There is no gap between the water and the railway bridge's girders, and all kinds of flotsam is accumulating at the girder. The water level has reached the settlement at the right of the image. Construction work on the elevated road to the left is continuing despite the spate.

These next images are from the elevated road construction site at Mathura Road. Construction-related vehicles that were in the nala have at least half their wheels submerged!
A truck, earth-mover and large crane inside the swollen nala. Next to the truck is a large pre-cast segment of the road. I don't think there is any danger of any of these washing away, though!
Here are images of the elevated road construction, which I'd gone to photograph.
