The Interdepartmental Directorate of North-West Roads (DIRNO) began Tuesday, April 19 the repair of the bridges of the arm of the Eure, on the RN 123, at the ring road south of Chartres, between Le Coudray and Morancez. A project called to continue until October 30.
Disturbed traffic
Throughout the duration of the works, traffic (as well as the insertion in this sector) is neutralized on a voice over a distance of approximately one kilometer, in the Paris-Dreux direction, at the level of the work zone. Traffic disruptions, more substantial during rush hours, are to be expected.
Reinforcement of nozzles
This project aims to internally reinforce two metal nozzles, with a reinforced concrete shell for each of them. This work was decided after the last inspections carried out on these culverts, built a little over 50 years ago, which revealed the presence of internal and evolving pathologies at the level of the tidal zones. Hence the overall repair undertaken in the short term, in order to guarantee the safety of users and the proper functioning of the works.
30km/h zones in Nogent-le-Rotrou from this Monday, January 24
Steps
Access to the site required controlled deforestation
. This will be followed by the creation of an access track and a site platform. The sludge, contained in the two metal nozzles, as well as those present in their immediate surroundings, will be evacuated, to allow the construction of the reinforced concrete shells.
The nozzle heads, visible in the form of embankments, will initially be concreted. In a second step, they will be secured by the installation of stairs and railings.
