“We are in the dark on the main axes,” reassures the Cord 57 (Operational Center of the departmental roads of Moselle) in the middle of the afternoon, while the clouds are still releasing snow on January 14.
On the secondary network, it is less obvious with the persistence of traces of snow and difficult traffic conditions on the heights and sectors with snowdrifts, where it was necessary to fight a little more to remove them. This was verified in the territory of Sarreguemines-Bitche, where 13 winter service vehicles came out at 2:30 am. It was even necessary to hire a loader from a local company to “erase” the wall of snow, high up in the snow. ‘about 1 m, placed on the shoulder of the RD35A between Bitche and the German border, in order to facilitate the passage of the salt spreaders and their blades, which are among the most early-morning in the department. They came out around 5:40 am in the two sectors of Forbach-Saint-Avold and Sarrebourg-Château-Salins and around 6:30 am to attack that of Thionville-Metz Orne.
The effort, sustained all day Thursday by 180 agents and 75 vehicles, is expected to continue until the middle of the night in the department and until the early hours for the Moselle valley. On the one hand, because the flakes will continue to fall without looking at the watch, but above all because of the negative temperatures at night (-2 ° C to -4 ° C), the first effect of which is to make the roads slippery. A risk integrated into the prefect’s decision to extend the ban on school and interurban transport until Friday 3 p.m.

“It reacts well”
Ice rink asphalt is also the concern of snow removal services in Metz. In the streets from 7 am Thursday (especially in the upper districts), the second wave of agents in the afternoon turned at night to treat the streets in which we expected from 1.5 cm to 2 cm of snow per hour until 10 p.m. “It’s wet snow,” says Lionel Krebs from the urban cleanliness technical operating center (CTE), where the machines leave. If, elsewhere in the department (as in Malancourt-la-Montagne), its weight caused damage to trees and vegetation, to the ground with 15 g / m² , “It reacts well”, estimates the specialist.
But the disadvantage of this advantage is that the melt water could turn ice during the night and occasionally turn the streets into an ice rink. The snow itself could finally hold onto the frozen ground and freeze over. It will therefore be necessary to measure the accelerations as the braking.
