In the UK, Transport for London (TfL) has published a report on the impacts arising from the construction of the London Underground Jubilee Line Extension (JLE). The main findings are that the JLE has delivered substantial benefits to London. These include helping maintain the city’s financial position by allowing further development of Canary Wharf, increasing the proportion of commuters using the Underground in the route corridor and saving an estimated 14.4M hours of travel time in its first year of full operation.
