The bridge is 30.25 m wide, 705 m long and has a bridge surface of 21,326 m². The largest height over ground is 60 m. It consists completely of a steelwork construction, whose rolling-element bearing rests on concrete pillars. In contrast to similar bridges, the roadways of both driving directions are carried by continuous elements. The construction of the bridge was finished in 1971.
Damage and closure
At 10:40 on August 26, 2004, a car collided with a tanker truck containing 32,000 liters of fuel on the Wiehltal Bridge. The guard rails were designed only to stop vehicles up to 13 tons and were unable to hold the truck, which fell 30 meters off the A 4 Autobahn and exploded. The truck driver was killed; the heat damage destroyed the load-bearing ability of the bridge and it had to be closed to traffic.
Provisional repairs were made in autumn 2004. Plans for a replacement bridge are expected to be formulated in the spring of 2005. Repairs are estimated at € 32 million and replacement could cost up to € 250 million, including the cost for disposing of the waste. This was by far the most expensive accident in the history of the Federal Republic of Germany.
