The intervention is due to start tonight at 10pm and will last until 6am tomorrow morning.

Drivers circulating on the road tonight are asked to take special care while on the six-kilometre stretch undergoing work.

The A5 motorway is one of the busiest in the country and used every day by some 120,000 drivers on their way into Lisbon. The work is to resurface the road between kilometre 18 and 23.
