The Valencia Street Circuit is a semi-permanent street circuit in Valencia, Spain. The circuit utilizes the roads skirting around the city's harbor and America's Cup port area, including a section over a 140 meter long swing bridge, and also includes some roads designed exclusively for racing purposes by the German architect Hermann Tilke who also designed the infrastructural buildings for the circuit. The track is 5.419 kilometers (3.367 mi) long and incorporates a total of 25 turns – 11 right-handers and 14 left-handers. It is estimated that the track has a top speed of around 323 kilometers per hour (201 mph). Valencia is not as tight as Circuit de Monaco but overtaking opportunities are still relatively few, due to the straights not being straight and the dust off line. Some corners have a lot of run-off area and good traction and braking stability are crucial to win at this circuit because there is a lot of long straight lines ending with heavy braking. The circuit has been criticized by the drivers for its lack of overtaking opportunities. There have only been 4 recorded overtakes since the race was first held in 2008, with none of them in 2009. There is little space for improvements to the circuit to address this problem.
