a World War II aerial bomb exploded while milling a cement-lime mixture in the new hard shoulder. A construction worker was killed, the milling machine was completely destroyed and several vehicles and buildings were damaged. During a subsequent unearned dupe search in the peripheral areas and at greater depths, even more duds were found. In a highway renewal work in the summer of 2014, a 500 kg heavy bomb from the Second World War was found on 19 August between the Offenbacher Kreuz and the junction Obertshausen. For defusing the A 3 between the Offenbacher cross and the junction Obertshausen was closed in both directions. Since it was not possible to remove the detonator of the British dud, the bomb had to be blown up on site. The result was a crater with dimensions of about 10 × 5 meters and a depth of about 3 meters. Furthermore, the road superstructure of the first lane and the stationary strip of the directional road raised up to about half a meter. The road to Würzburg was closed until 21 August. Current state Netherlands to Cologne The A3 is four-laning for the first 65 kilometers (41 mi) up from the Dutch border. There are six lanes, three lanes in each direction, between interchange Kreuz Oberhausen and Köln-Mülheim. On a short part inside of Kreuz Kaiserberg the A3 has two lanes. The Autobahn is equipped with eight lanes on the Cologne Beltway between Köln-Mülheim and autobahn triangle Dreieck Köln-Heumar. Cologne to Aschaffenburg The course until Waldaschaff near Aschaffenburg has six lanes. The A3 is seven-laning between Mönchhof-Dreieck and Wiesbadener Kreuz (four lanes in the direction of Cologne, three to Würzburg) and eight-laning between Frankfurter Kreuz and Offenbacher Kreuz. Aschaffenburg to Fürth The A3 has only four lanes from Aschaffenburg-Ost to the junction with the A 73 Kreuz Fürth/Erlangen in 2009. The Spessart-slope near Waldaschaff and some slope areas near Würzburg have additional lanes. There are plans to expand this area of the A3 up to six lanes in the next few years. The construction between Hösbach and Bessenbach/Waldaschaff was finished in 2011, and the new building of the Haseltalbrücke was terminated in 2012. The section in the area of Würzburg — from the border between Baden-Württemberg and Bavaria near Helmstadt to Würzburg-Heidingsfeld and from Würzburg to Rottendorf — was expanded until 2012. The next kilometers between Rottendorf and interchange Kreuz Biebelried was in
