The increasing population of DKI Jakarta has resulted the demand of transportation vehicles grow which causes the traffic jams in the Capital of Indonesia to get worse. To overcome this problem, the local government decided to build flyovers and one of them is Kelapa Gading – Pulo Gebang route. This final project will discuss the drainage system at Sector A1 P8.1 – P8.11 precisely on Boulevard Barat Raya street in Kelapa Gading, North Jakarta. From the calculation of Rational method, the result of Qb is 0.0546 m3/s for the channel above the flyover. From the result of those calculation, the calculation of all drainage channels are: (a) There are 280 deck drains with dimension of 180 x 380 x 250 along the flyover (b) The upper horizontal A and B drainage channels made of concrete blocks has a diameter of 10” with a channel slope of 0.5% while for vertical channel has a diameter of 12” (c) The lower median channel uses U-Ditch with a size of 100 x 100 which has slope of 0.2% (d) The lower side channel uses U-Ditch with a size of 120 x 120 which has slope of 0.3%.
