Entailment: The construction of the Haifa-Damascus railway and the massive new harbour transformed it into the vital trading and communications centre it is today; before, the city had a farily nondescript history.
Contradiction: The massive new harbour was supposed to be built in the city, but they suspended the construction indefinitely.
