When will there be gritting?

Based on weather information, contact with a meteorologist (in some cases) and our own observations, we determine whether gritting is necessary. In the menu below you can see at what time gritting was done and which route was driven.

Gritting routes

There are 2 routes for gritting. Which route is driven depends on many different aspects, such as frost, humidity and cloudiness.

Limited route

When the limited route is gritted, the route passes main roads, major thoroughfares, on- and off-ramps and critical points that freeze quickly. These include some bridges, overpasses and roads along water. We also call these the 'coldspots'.

Full route

In the full route, main major thoroughfares, roads, access roads from neighborhoods, driveways and exits, main bicycle paths and coldspots are gritted.

There is no gritting on footpaths, smaller bike paths and streets in residential areas. There are several reasons for this. For example, because the gritters cannot get everywhere and because there is limited time to grit. So always pay extra attention in these places when you go out on the road.

To map of gritting routes

What can you do yourself?

When it snows, it is best to clear the sidewalk of snow. Remove the snow with a shovel and throw a small layer of road salt on the sidewalk or street. Together with your neighbors, this will keep your street safe and accessible. You can buy road salt and a snow shovel at one of our city's hardware stores.

Helpful tips

  • Leave home on time. This will prevent time constraints and dangerous situations.
  • Keep in mind that some places may be extra slippery. For example, bridges, overpasses and places where the pavement changes.
  • Scrape all your car windows thoroughly with an ice scraper. Also check that your headlights are free of snow and ice.
  • Remove snow from the roof of your car. This way, it will not fall off while driving. 
  • Park your car in gear and don't use your handbrake. This way the handbrake can not freeze stuck.
  • Beware of fast steering, fast acceleration and heavy braking.
  • Slow down for turns and don't take them too fast.
  • Wear shoes with a good tread pattern.
  • Remember that it can be slippery even though it has been gritted.

Frequently asked questions about slippery conditions and gritting

Why is it sometimes still slippery, even though grit there has been gritted?

It may take a while for the road salt to take effect. This is because it needs to be driven over a few times. Roads that are less frequently used may therefore still be slippery. So even if we gritted the roads, take care when driving.

Why does the municipality sometimes grit when the weather forecast does not indicate that it will freeze?

This is because the temperature of the road surface is sometimes colder than the air temperature. It is possible that there is a lot of cold in the road, even though it is not freezing above the road. In that case, we still spread grit as a precaution. It is also possible the other way around. So the road has still enough warmth in it, even though it is freezing in the air. In that case, we do not need to grit.

Why doesn't the municipality grit residential streets and footpaths?

There are several reasons for this, but these are the most important ones: There is a strict time frame in which gritting can take place. This means that the most important roads have the highest priority. These are the main roads and access roads. In addition, footpaths are not gritted because gritting trucks cannot be driven on them.

Are bike paths always gritted?

No, the bike paths are only gritted when we ride the entire route, and then only the main bike paths. So please take care when cycling in slippery conditions.

Why are the posts in the middle of bike paths removed when it freezes?

We are removing the posts so that the gritting trucks can also reach the bike paths.

Can I spread road salt around my house myself?

Yes, you certainly can. You can clear the snow from the sidewalk in front of your house and sprinkle a small amount of road salt. A small amount is sufficient to prevent slipperiness, and too much salt is bad for the environment. You can buy road salt at hardware stores in the city.

Can I also sprinkle table salt in front of my house?

No, table salt does not have the same effect. To prevent slipperiness, you need special road salt. You can buy road salt at hardware stores in the city.

Where can I report a slippery road or dangerous situation?
