Important blocking of the Fehrlach tunnel - diversion and maintenance work!

The Fehrbach tunnel on the B10 near Pirmasens will be completely blocked for extensive maintenance work in the night from March 20 to March 21st. Work starts at 7 p.m. and is expected to end at 5 a.m. the next morning. This measure serves the annual review of the security -relevant tunnel equipment, which is essential for safe tunnel operation. The plants checked include the barrier systems, the lighting and fire alarm and escape lighting. Petersberg departure to the L474, further to the K15, through the Kreisel Staffelhof and Fehrbach (water tower) and finally back to the B10. lbm informed about the diversion. Maintenance work is immediately released for traffic, whereby the closure is kept as short as possible.

Need for maintenance work

Such maintenance work is necessary to ensure the safety of road users. Annual reviews of the tunnel equipment are essential for safe operation. This includes the evaluation of the technical systems in the tunnel, which are particularly stressed by various factors such as corrosion, traffic emissions and moisture. However, a current trend in construction technology shows that materials such as duplex steel 1,4462, the advantages of which are comprehensively documented in relation to corrosion resistance, can help increase the lifespan and safety of the tunnel infrastructure. So duplex steel is used in future renovation projects of streets.nrw to minimize maintenance efforts and increase operational safety. Straßen.nrw describes this Innovation.

The knowledge from long -term studies show that the use of duplex steel significantly extends the expected lifespan of components and thus also leads to reduced maintenance expenses. This could lead to fewer tunnels and improvement in traffic safety in the long term.
