Loading 16,971 bridges
In this map we have plottet all bridges on Norway’s national and county roads.
Most of the information is from March 2017. The sources are the National Public Road Administration’s (NPRA) internal database Brutus and open data from the map service Vegkart. Some bridges are missing from the map, mainly new bridges or bridges having recently changes bridge number.
You can choose between three different map layers:
Here we have marked damages logged as ‘serious’ (‘stor’) or ‘critical’ (‘kritisk’) for load capacity or traffic safety by the NPRA or their contractors.
The information in this layer is from Brutus, September 2017.
Action points not carried out
For each bridge in Brutus, the NPRA can register action points which should be carried out on the bridge. When the action point has been carried out, it changes status from ‘planned’ to ‘carried out’. Here we have marked bridges with suggested action points still having the ‘planned’ status, even though the proposed execution date was in 2016 or earlier.
The information in this layer is from Brutus, March 2017, and is supposedly updated with all actions in 2016. Action points executed in 2017 can not be expected to be updated on the map.
Most bridges have a mandatory main inspection every five years, and a basic inspection every year. Here we have marked bridges which lack inspections with deadline 2016 or earlier.
The information in this layer is from Brutus, March 2017, and is supposedly updated with all actions in 2016. Inspections executed later can not be expected to be updated on the map.

Below, VG has summarized the report for :
When a damage is discovered on a bridge, it is evaluated with a severity grade, a consequence grade and a damage type.
Severity grade is stated on a scale from 1 to 4, where 4 is most critical.
Consequence grade is also stated on a scale from 1 to 4, where 4 is most critical.
Along with the consequence grade, a letter shall indicate what kind of consequence is in question. There are four consequence types: load capacity, road safety, maintenance and environment.
VG has received a statement of all damages on load capacity or road safety, with severity grade or consequence grade 3 or 4.
Eventually, the severity grade and consequence grade are multiplied into a priority on a scale from 1 to 16. The most critical damages have priority 16B (load capacity, bæreevne) or 16T (road safety, trafikksikkerhet).
A vulnerability is a known weakness, which is not a damage.
A common example is an old railing which does not fulfill today’s requirements. Before the vulnerability category was introduced, old railings were often logged as damages, even if they were not damaged.
Main inspection: Extensive check of the entire bridge above water, normally every five years. Shall be logged.
Basic inspection: Less thorough, visual inspection of all bridge elements above water. Normally every year, but can be omitted in the year of a main inspection. Shall be logged.
General inspection: Visual control of road stretches. Can be carried out from a car at slow speed, with stops at certain objects. Every week or every second week. Are not logged.
In this presentation, we mark as a deviation where too much time has passed since the last inspection.
Brutus is also used as a planning tool for large and small action points on the bridges. When an action point has been carried out, it remains in the list, but it changes status from planned to carried out.
In this listing we mark as a deviation if an action point has an execution date in 2016 or before, and still has the status ‘planned’. But the date is only a suggestion, so this is not a violation of any rules.
