A couple questions ...
1) why, when resurfacing a highway, do they skip over overpasses ? They've "munched" the road surface on both sides of the overpass, but left the overpass decking. This noticed on the 401 in Toronto.
2) why do they use concrete as the top surface on highway on ground level, but bitumen for overpasses ? This noticed on the 407, north of Toronto.
another day in paradise, or is paradise one day closer ?
