Preservation programme and
rehabilitation measures for the highway forming the Northern access to the St.
Gotthard
pass and tunnel are described. After a short historical background the
preservation programme is explained with emphasis on systematics concerning
grouping of the network, guidance of traffic, planning and execution phases and
categories of intervention. Financing and organisation as well as the actual
state are briefly mentioned. Finally, some groups of structures like bridges,
galleries and retaining walls are mentioned, highlighting problems and
solutions common to these groups and some special measures taken or in
progress.
