Can infrastructure building be sped up?

Question

I was watching road construction and it seemed to me like adding more trucks wouldnt help the problem. The trucks were just backed up because only one could work on each lane. Adding more trucks in front would do nothing because there was only one road grader possible to ensure a single consistent grade. You could argue that multiple roads could be built in parallel to circumvent this linear process. But you need something specific to build a road towards. There are no such cases to my knowledge except a handful of urban areas with congestion, or some minor rural areas with unpaved roads. Is it even possible for more infrastructure spending to result in more roads?

Answer 1

Oftentimes, private companies are paid more if they work longer. The slower they work, the more money they are paid because the duration is longer. Because of this, construction workers are in no hurry to get a job done. Even when construction is finished, roadways do not open up right away as there are usually ribbon cutting ceremonies for the press.

Efficient planning as well as a set amount of money being paid to private companies to stop manipulation would allow for roads and other infrastructure to be built faster. I have seen where paving trucks pave patches of roads in sections until all is complete. If a two lane road is being paved, you pave two lanes until it is all the way complete. You don't do a whole lane and go back to the beginning to finish the second one.
