response from another friend

The southern is O.K. but below standard of most new highways in Guate
or El Salvador - worse, it is degrading as no maintenance is being
done.

As it was done with the old-style tar poured over crushed gravel it is
not holding out. Many patches are worn out and slick in the rain.

I have no idea why they are still using the old method to build new
highways - unless commissions for the pols are better to hide in the
books this way.
