This is from 'Mothers and Sons' by Colm Toibin.
It was March and a thin frost was beginning to settle. The road had been widened for stretches, and the car lights beamed on wooden fences instead of the old ditches. The road was no more the hidden, almost guilty thing it had been, huddled away from the land around. There were fewer accidents now, she supposed.
I looked up the definition of stretch and still not sure which one. Is the road widened in terms of a width only or a continuous length?
