According to Lisbon Town Hall, the work will last for three months, with a series of detours and closures expected to result from the renovations to the city’s road network. Areas affected include Carnide, Chiado and in particular the area between Belém and Alcântara, where the re-paving of sidewalks has been made a priority. Officials said police will be on all sites and signage will be extensive to minimise disruption.
