The Weser tunnel in the course of the B 437 was opened to public traffic in 2004. After more than 15 years of operation, part of the technical equipment is subject to change and must be replaced or upgraded. The now updated regulations and the need for higher availability for road users in future (minimization of blocking times through maintenance and repair) must be taken into account. In addition, measures, structural and technical, have to be carried out due to the change (increase) in the forecast traffic figures.

The subject of this tender are the holistic planning services required for this.
