How Did They Do It?

Last year, for an entire road construction season, a road that I use daily was closed so that a center turning lane could be added. It took the whole year to add one lane to about a one mile length of road. (Most of the time it seemed like they weren't doing anything).

So I did some figuring, just recently. At the rate that project was completed, it would have taken 1244 years to build Interstate 80 across Pennsylvania!

So I'm wondering...given the above calculation, and how long it takes to complete ANY road project these days, how did they actually ever build the interstate? Guess they must have worked faster back then, or something. Or they just did such a shoddy job that it's no wonder it has to be rebuilt EVERY YEAR!
