Yes, please! To me it feels like 90% of road works I pass actually has nobody there working at all. Some go on for years it seems.

Another option is what they do in Japan - just get 10X the number of people on it, with all the tools for the entire job and then do it all overnight.

Also, nice to see good old "dude with shovel" in there, a tool that would have looked the same back in the 19th century.
