Highway engineeringHighway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods. Highway engineering became prominent towards the latter half of the 20th century after World War II.

Volkswagen BeetleThe Volkswagen Beetle—officially the Volkswagen Type 1, is an economy car that was manufactured and marketed by the German company Volkswagen (VW) from 1938 until 2003. It has a rear-engine design with a two-door bodystyle and is intended for five occupants (later, Beetles were restricted to four people in some countries). The need for a people's car (Volkswagen in German), its concept and its functional objectives were formulated by the leader of Nazi Germany, Adolf Hitler, who wanted a cheap, simple car to be mass-produced for his country's new road network (Reichsautobahn).
Bundesautobahn 9is an autobahn in Germany, connecting Berlin and Munich via Leipzig and Nuremberg. It is the fifth longest autobahn spanning . The northern terminus of the A 9 is at the Potsdam interchange, where it merges into the A 10, also known as the "Berliner Ring", about away from the Berlin city limits. The shortest route from there into Berlin would be the A 10 (east) and the A 115 (AVUS). The southern end is in the Munich borough of Schwabing. On its way, the A 9 passes through the German states of Brandenburg, Saxony-Anhalt, Thuringia, and Bavaria.
ChemnitzChemnitz (ˈkɛmnɪts; from 1953 to 1990: Karl-Marx-Stadt kaʁlˈmaʁksˌʃtat, Karl Marx City) is the third-largest city in the German state of Saxony after Leipzig and Dresden. It is the fifth largest city in the area of former East Germany after (East) Berlin, Leipzig, Dresden and Halle. The city is part of the Central German Metropolitan Region, and lies in the middle of a string of cities sitting in the densely populated northern foreland of the Elster and Ore Mountains, stretching from Plauen in the southwest via Zwickau, Chemnitz and Freiberg to Dresden in the northeast.
Median stripThe median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved, but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping, trees, a median barrier, or railway, rapid transit, light rail, or streetcar lines.
Grade separationIn civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways.
