Just admire the way they performed the work and the modern machinery used to complete the task. Here in our place we still use the pre- historic machines.What a great dedication to work. Hats off to those guys who are working.I recall about 30 years ago, my local city experimented with a something called 'glassphalt'. It was a way to use recycled glass, it was mixed into the asphalt. The roads it made were gorgeous, they actually glittered, especially at night as you drove along them. Sadly, they stopped doing it because crushed rock was much cheaper.
