The Markusberg tunnel ( Luxembourg : Markusbierg) connects the Schengen (13) and Bad Mondorf (Mondorf-les-Bains) (12) exits of the Luxembourg A13 motorway with each other.
It was built from April 1998 to November 2002 on behalf of the Ministère des Travaux Publics (road construction administration) in Burmerange and Remerschen . The construction costs amounted to € 44.25 million. The opening took place in July 2003.
Technical details
- Number and length of the tubes : 2 tubes with 1565 resp. 1585 m length
- Inner radius of the tube : 5.2 m
- Width of the lane : 7.0 m; Height: 4.8 m
- Height difference entrance / exit : 74.35 m
- Slope of the tunnel : 5%
- Covering over the tunnel : variable between 4 m and 50 m
- Distance between the two tubes : variable from 8 m to 17 m
- Number of emergency bays : 22
- Underground erosion : 265,000 m³
- Number of moorings : 47,000
- Quantity of shotcrete required : 33,000 m³
- Weight of the steel structures : 1,300 t
- Amount of concrete for the tunnel inner shell : 35,000 m³
The tunnel has seven connecting tunnels , each 200 m apart, which are kept permanently under pressure. There is a passage between the two tubes for rescue vehicles.
The tunnel is equipped with the most modern fire protection devices such as linear temperature detectors, stationary foam extinguishing systems and special fire service control cabinets.
The maximum speed in the tunnel is 90 km / h. This can be visually displayed with the help of the curb lights. The driver is discreetly reminded of the maximum permitted speed and at the same time he can see whether he is faster or slower than the running lights. There are also large text boards at the two entrances that display current information about traffic in the tunnel or on the further route.
Award
In January 2008, the Markusberg Tunnel, along with three other tunnels in Europe, received the “Best Tunnel in Europe” award, which is presented by Eurotap (European Tunnel Assessment), a European tunnel testing committee . The tunnel was awarded the grade “very good” in all test areas.
Problems in the tunnel
The tunnel has had to be closed several times since it opened in the summer of 2003 due to enormous uneven roads. According to the head of the road construction administration, Georges Simon, these are caused by large amounts of water, some of which are up to 50 m below the tunnel floor. As a result, the layers of the earth do not come to rest and the tunnel has to be closed. This was last the case in November 2008, when the tunnel was closed for two weeks.
