According to the new Modern Railways, the existing A13 is going to be
buried as it goes near Barking Reach to create room for more housing.
Meanwhile, the entire new railway to Barking Reach is built on a
viaduct. They say that the water table is pretty high there, but while
that would create problems for tunnelling, I don't think it would be too
much of a problem for cut and cover.
