Limits on Bridging Structures Located on Main and Regional Roads

Monday, January 20, 2014 8:56:51 AM

As of 18 January 2014, the Slovenian Roads Agency (DRSC) is limiting the maximum allowable weight of vehicles that may cross eleven bridging structures on main and regional roads. The Agency  also introduced alternative one-way traffic on four bridging structures as of 25 January 2014.

The establishment of these limits and alternative one-way traffic systems are necessary in order to ensure the safe flow of traffic, as some structures are worn to the point of not being able to support certain weights. The almost 6,000 km of roads that fall under the purview of the DRSC, contain 1,080 bridging structures spanning between 3 to 5 meters, as well as 1,403 bridging structures with a span of over 5 meters.  Following regular and main inspections, it was established that the state of some of the structures had reached a point where they were no longer able to support the necessary traffic load.

In order to ensure the safety of traffic and people’s life and health, as well as to prevent major property damage, the Slovenian Roads Agency was forced to put in place measures that will establish the maximum traffic load on these structures, thus ensuring safe traffic flow. The current number of these structures stands at 15 (see a list of the structures below). Roads Agency expects that the list will have to be expanded to include additional structures following new measurements in the coming months. Some road sections are also worn out to such an extent that they cannot be rebuilt to an adequate state using available funds, which means they will need to be closed if more damage occurs.
