People heading to the beach, a festival or an outdoor event this weekend are being warned to plan ahead, as hot weather, road closures and major roadworks are likely to lead to widespread congestion.

One of the biggest disruptions will be in Amsterdam, where the long-planned “Op de Ring” festival is taking place on the A10 ring road to mark the city’s 750th anniversary.

From 9 pm on Friday until 3 pm on Sunday, the western, southern and eastern sections of the A10 will be closed to traffic, including the junctions with the A2 and A4. The infrastructure ministry warns the closures could add at least 60 minutes to journey times.

The Zandvoortselaan, one of only two roads into the seaside town of Zandvoort, is also closed until  Monday at 7 am. The closure, near Heemstede-Aerdenhout station, could make a beach trip difficult — especially with the temperature forecast to reach 30°.

Train services between Haarlem and Zandvoort are also cancelled from Friday night to Monday morning. NS will operate replacement buses, but delays are expected due to the large number of visitors heading for the coast.

In the south of the country, the Pinkpop music festival in Landgraaf is expected to draw 60,000 people per day from Friday to Sunday and could lead to congestion around the festival grounds, the local council said.

Traffic is also expected to be heavier than usual near the German border and in Zeeland due to Sacramentsdag, a national holiday in Germany. Many Germans are heading to the Netherlands for a long weekend.

Disruptions are likely to continue into next week as the Nato summit gets under way. From Sunday afternoon to Thursday, roads in and around The Hague, Amsterdam and Rotterdam will be severely affected.

Sections of the A5, A44 and N44 will be closed, while restrictions will apply to parts of the A4 and nearby provincial and local roads around Katwijk, Noordwijk, Wassenaar and Leiden.

Travel plans

A ministry spokesman told the Telegraaf earlier a snap survey found little enthusiasm for changing travel plans during the summit.

“Virtually everyone is aware of the summit and the potential problems, but only 16% expect to be affected, and fewer than 29% are willing to change their travel behaviour,” said Diederik Fleuren. “That’s far too low — really, half the traffic needs to stay off the roads. Otherwise, the Randstad will be gridlocked for four days.”
