The A1 becomes a moving work zone today

A navigation app may still show the A1 as open, yet the first narrow lane and a chain of braking cars can consume a small morning buffer. The trap is treating today as one closure: this is a sequence that changes direction, section and access point through the autumn. Westbound traffic between Apeldoorn-Zuid and Kootwijk narrows first, with eastbound measures following and separate night closures layered over them. Some ramps and service areas remain unavailable longer. Rijkswaterstaat advises that extra travel time can reach thirty minutes, while incidents and peak demand may add more. A new Barneveld–Apeldoorn phase starts today, combining 70 km/h narrow lanes, night closures and changing Hoenderloo ramp access on different dates.

• Westbound narrow lanes begin at 05:00 on 18 August.
• Some sections operate at 70 km/h.
• Officially advised delay can reach thirty minutes.
• Night closures continue in later phases through December.
• A new Barneveld–Apeldoorn phase starts today, combining 70 km/h narrow lanes, night closures and changing Hoenderloo ramp access on different dates.

Hokimi field note:Before leaving, match the calendar date to your direction and intended junction. Build a thirty-minute margin into a cross-region commute. For Hoenderloo, verify the exact numbered on-ramp or off-ramp instead of assuming an open main carriageway means access is open.
