The Messeschnellweg begins in the north in the district of Groß-Buchholz at junction 5, Hanover-Misburg, A37. It runs in a southerly direction east of the Hanover city, centre through the Eilenriede. Then it passes the eponymous exhibition centre in the district Mittelfeld () and ends in Laatzen-Mitte. Here it goes back into the A37 (junction 11 fairgrounds), while at the same time the B6 branches off to the south. The preparations for the construction of the Messeschnellweg already  began in 1949. Together with the Südschnellweg, the Westschnellweg and other expressways, it is part of the concept developed by the then city planner Rudolf Hillebrecht to guide long-distance traffic around the city center. The construction of the highway through the middle of the Hanover city forest Eilenriede led to violent protests in the population, which resulted finally in 1956 the city constituted the Eilenriede Advisory Board. The expressway is developed as a four-lane motor road. It is crossing-free since 1998 (completion of the underpass at the Pferdeturmkreuzung ) and partly has a stand track. A traffic control  system makes it possible to use this as an additional lane for major events. During the big trade fairs (Hannover Messe, around the turn of the millennium the Cebit, later the Agritechnica) the Messeschnellweg is regulated as a one-way street at peak times (arrival and departure, sometimes only on the busiest days), so that four lanes can be driven in one direction are.
