# Bundesautobahn 66

Bundesautobahn 66 (translates from German as Federal Motorway 66, short form Autobahn 66, abbreviated as BAB 66 or A 66) is an autobahn in southwestern Germany. It connects the Taunus to Fulda, passing close to Frankfurt am Main. The first part of the autobahn, between Wiesbaden and the Nordwestkreuz Frankfurt, was opened as early as 1934, then called the Rhein-Main-Schnellweg. It became an autobahn in 1965.
The autobahn is incomplete; there still is a gap within Frankfurt city borders. A tunnel was proposed as a solution; however, this has not been implemented because of the high cost of construction. A new section of roadway to close a second gap southwest of Fulda was opened to traffic on 13 September 2014. The section includes a 1.6-kilometre (1.0 mi) cut-and-cover tunnel and replaces a diversion which saw traffic routed onto the B 40 for approximately 9 kilometers before rejoining the A 66 just prior to the junction with the A 7; the new segment cost 154 million euros. A portion of the Kinzig Valley Railway line was also rerouted along the new autobahn segment, which cost an additional 60 million euros.
Near Frankfurt-Höchst, the highway is one of the busiest in Germany with an average of more than 130,000 vehicles per day.
Between Zeilsheim and Eschborn the A 66 follows the course of a Roman road, which later in the Middle Ages had been given the name Elisabethenstraße, because it was part of the pilgrimage route to the grave of Elizabeth of Hungary in Marburg.
