Drivers leaving The Hague’s Wateringse Veld for the N211 have faced long morning queues since a new roundabout and fly-over opened.
Where the route towards the A4 once had three lanes, there is now one, plus a traffic light at the end of the fly-over.
Drivers complain the trip now takes at least half an hour longer, despite millions spent on the rebuild.
The province of South Holland says the temporary light is needed to let traffic merge safely, because the flow on the N211 from the Westland and The Hague is heavier than the traffic out of Wateringse Veld.
The light will go once the N211 has three lanes, but the single lane from the Laan van Wateringse Veld is permanent.
Provincial traffic models indicate one lane will be enough when the lights on the N211 are gone and traffic flows continuously across three lanes.
The temporary signals will only disappear when the whole project is finished, including the widening to three lanes each way and a sunken section at the auction route, which the province puts at the end of 2027.
The province says it is monitoring the lights and traffic flow daily to improve the settings.
