context_page_description: The Marina Bay Street Circuit is a street circuit around Marina Bay, Singapore, encompassing the planning areas of Downtown Core and Kallang. It is the venue for the Singapore Grand Prix. The track is 5.063 km long in a harbourside location similar in style to the Circuit de Monaco and the Valencia Street Circuit.
  The circuit is designed by KBR, Inc., a modification of the original one first proposed by Hermann Tilke. The circuit has a FIA Grade 1 license. The circuit holds a unique record of having at least one safety car appearance in every race to date. There has been a total of 21 safety car deployments in twelve races.
context_section_description: Marina Bay Street Circuit starts with a specially made pit straight with the first DRS zone. The pit straight approaching just below the Benjamin Sheares Bridge at a speed of 308 km/h (191 mph) before braking into left-hand turn one to 126 km/h (78 mph). The opening sequence of turns one, two, and three are shaped like an 'S', a curve to the right for turn two, while turn three is to the left at just 83 km/h (52 mph). Now, the car is on Republic Boulevard (along turn 4) speeding up to 260 km/h (160 mph), then heading to right-hand turn five, braking to 145 km/h (90 mph). On Raffles Boulevard (where the second DRS zone is located), flat-out for turn six, to the fastest part of the circuit at speeds of up to 320 km/h (200 mph). Cars enter the apex at turn seven under heavy braking, slowing from 320 km/h (200 mph) to 111 km/h (69 mph). 
  Turn the car slightly to the right at the start of Nicoll Highway, picking up the throttle to 205 km/h (127 mph), braking to the right for turn eight to 68 km/h (42 mph), onto Stamford Road at 191 km/h (119 mph), before braking to 115 km/h (71 mph) entering turn nine. The braking leads to the St. Andrews Road (in front of the Padang), reaching speeds of 276 km/h (171 mph). Turn ten is a left-hand turn at 115 km/h (71 mph). Turns eleven, twelve, and thirteen were reprofiled before the 2015 Singapore Grand Prix. Drivers still turn right at turn eleven, but it will now kink left slightly on entry, with the track shifting to the left-hand side of Fullerton Road. This will change the profile of turn twelve, as drivers will now use the other side of the Anderson Bridge at 167 km/h (104 mph), while the hairpin at turn 13 (in front of Fullerton Hotel) has been widened by a metre in order to increase overtaking opportunities with braking to 110 km/h (68 mph).
  The car is now at Esplanade Bridge (where the third DRS zone is located) crossing the Singapore river, building up speed to 285 km/h (177 mph). Turn 14 almost meets turn eight, diverting to the right at 78 km/h (48 mph) onto the Raffles Avenue (in front of Esplanade). Next, a series of mostly blind corners from turn 15 to 19. The cars approach to the front of the floating platform grandstand (turn 16 and 17), then goes under the floating platform grandstand (turn 18 and 19) at 80 km/h (50 mph). At turn 18, cars must turn in at a specific angle, otherwise will brush or crash along the wall. Turn 20 and 21 is just after Bayfront Avenue; a right-hand turn 20, then a left-hand turn 21 that leads the car towards turn 22. How fast the cars approach turn 22 is determined by the exit of turn 21, therefore most of the drivers exit turn 21 very close to the wall to gain a speed advantage. Running down towards turn 22 passes the 165m tall Singapore Flyer, where turn 22 and 23 is taken flat-out at about 180 km/h (110 mph) before picking up the throttle again towards the pit straight across the finish line.
