The Office Fédéral des Routes en Suisse (OFROU) has entrusted Egis with full design and project management to improve the safety of a 9 km section of the route
nationale No. 5.
This road, which crosses the city of Neuchâtel, includes seven urban tunnels which no longer meet safety requirements of the OFROU. Upgrading these structures should allow for safer operation of this section of road. A key constraint of the project is the high traffic flow, to be maintained throughout construction.
Egis is conducting all engineering design work and will oversee construction and hand over, the expected project duration is seven years.
