Bicycle and pedestrian

edit

Most of the tunnels listed were built for other purposes, and have not been redesigned. The Fyllingsdalentunnelen is one example of a tunnel built to purpose from the start.

The tunnels listed here can be either be pure cycling tunnels and/or pedestrian tunnels with separate tubes, or shared-use tunnels (i.e. having a shared lane, or a bike lane and footpath without a non-crossable physical separation).

Archived from the original on 2013-12-13. The EVINOS-MORNOS tunnel project with its 30 km of length is one of the longest hydraulic tunnel in the world realised with TBM method. The adverse geological conditions, the high cover and the short construction schedule were a great challenge for the successful construction of this tunnel. The paper will describe: the criteria adopted for the tunnel design, the selection of the construction methods and equipment, the productions of the 4 TBMs adopted and the comparison of the behaviour of the different type of TBMs in the various rock conditions, including special conditions, the characteristics of the adopted in situ and precast linings, a comparison between the foreseen and actual construction schedules, the contractual implications of realising a tunnel in such a severe and complex conditions.
