It's been two weeks now.

They could leave it, we have some concrete roads around here.

I remember when major roads like the A34 between Oxford and the M40
were made up of concrete slabs, with tar expansion joints. Not a nice
road surface to drive on - very hard (tarmac is hard, but there's a bit
more give in it) and the thump-thump-thump of each joint gets very
annoying after a few seconds ;-) About the only thing in their favour
was that concrete roads were very hard-wearing and didn't need
resurfacing every few years.

There is a section of the M25 a bit like that Ashstead/ Reigate area.
