With apologies to AECOM, we would like to correct a mistake in the article on page 6 of the November 2017 issue in which we stated that the traffic forecast for Sydney’s Lane Cove tunnel was done by AECOM. In fact, it was done by Parsons Brinckerhoff, now WSP. It’s important because PB, not AECOM, is reported to have settled a lawsuit stemming from Lane Cove forecast mistakes for $121 million.
