Nearly half of tunnels in Norway do not qualify for having emergency network equipment, reports say.
Demands set out in 2004 state this must installed in tunnels over 500 metres (about 1,640 feet) with a minimum of 5,000 cars using them a day.
214 out of 498 tunnels are considered either too short or do not have enough daily traffic to install an emergency network.
These figures may seem alarming, and the confusion does not stop here. Several sets of rules are applied differently.
49 of these 214 so-termed non-eligible tunnels are more than 1,000 metres long (some 3,280 feet), 43 are between 500 and 1,000 metres.
The remainder are less than 500 metres – give or take one tunnel or so. Nationen also reports western Norway has two-thirds of these tunnels.
Moreover, any new tunnels constructed that are more than 500 metres long will have the emergency network installed even if the traffic usage is low.
“According tunnel safety regulations, which are based on an EU directive, only tunnels longer than 1,000 metres with 4,000 plus vehicles a day are required to have the emergency network [installed],” Norway Public Roads Administration (NPRA) official Arild Petter Søvik told the paper.
“In other words, the system regarding installation of emergency network in Norwegian road tunnels is well within the regulations’ requirements,” he added.
