middle of the bridge. The measurement takes place via induction loops in the road surface. The taking of fines and custody was until the recent closure of the bridge for vehicles over 3.5 t far below the expectations of local authorities. The State Road Construction NRW plans to replace the current Rhine bridge by the construction of a ten-lane motorway bridge. Construction is scheduled to begin in 2017, and from 2020 (completion of the first new bridge section with five lanes) the current bridge will be demolished and the second bridge section of the new building built. The plan is criticized by local politicians because of the structural impact on the city of Leverkusen, as alternatives, the construction of a tunnel through Leverkusen city or an extension of the A 542 brought by new construction of another crossing of the Rhine. On 14 December 2017 the official groundbreaking ceremony for the construction of the bridge took place. At the Eifel The gap between the current motorway ends at Blankenheim and Kelberg, not far from the triangle Vulkaneifel, is still largely planned. Of the approximately 25 km long gap are about 15 km in the responsibility of construction of North Rhine-Westphalia, the remaining 10 km are to be realized by Rhineland-Palatinate. However, since the planning approval decisions have had to be amended several times since 2005, a gap closure is not expected before 2019. The new construction of the A 1 through the Eifel, planned since the beginning of the 1980s, was completely included in the priority demand of the Federal Transport Infrastructure Plan 2003. Since 2004, the nature conservation appraisal has examined whether the planned route from the junction Blankenheim in the south to the junction Kelberg is environmentally sustainable; the corresponding results were included in the planning approval procedure. This was started for the northernmost section in North Rhine-Westphalia between the planned junction Lommersdorf and the connection point Blankenheim in May 2012; the other sections to Adenau and Kelberg are in nature conservation planning. The gap closure will cost around 400 million euros. The aim was to obtain a building permit for the remaining sections of the line by 2010 and to close the gap completely by 2015. While many local residents and business representatives welcome the closing of the gap, nature conservation associations announced a judicial resistance. Planning has also been stalling for years due to environmental law,
