Extended roadworks on the A44 highway toward Amsterdam have caused severe traffic congestion on the alternative A4 route, with delays exceeding one hour for commuters on Tuesday, June 30, 2026.
Omroep West reported a 25-kilometer traffic jam between Den Hague and Leimuiden at 8:15 a. m.

, marking the second consecutive morning of major disruptions on the A4 corridor.
Rijkswaterstaat extended the maintenance project by two days because extreme summer temperatures prevented crews from working around the clock.
The highway is now expected to reopen on Friday, July 3, 2026, at 6:00 a. m.
Viaduct Replacement Underway
The current phase involves replacing the 90-year-old Lisserweg viaduct, requiring a full closure of the Amsterdam-bound A44 from the Noordwijkerhout exit to the Burgerveen junction.
Rijkswaterstaat representative Dick van der Kolk explained that schedule adjustments were necessary to ensure crew safety during peak daylight heat.
"It has everything to do with the weather," he said. "We must protect our people.
So we will carry out as much work as possible outside peak times, at the edges of the day.
It is not possible to work 24 hours a day."

Van der Kolk noted that the historical structure had deteriorated over decades of heavy use. "That is very badly needed.
We are talking about a 90-year-old viaduct that even survived the war. Due to intensive use, it is now really due for replacement."
