Abstract

Denpasar represents a town with the amount of most residents in Bali and has a tendency will increase. This of course will be followed by accelerating the development of various sectors. This condition will be creating various urban problems, among the other problem is the jam of traffic, which is caused by the existence of unbalanced growth of very fast vehicles (14%) compared to with accretion of new streets which only reaching 3,6% a year. To overcome the problem one of the efforts able to be conducted is by improving the quality of street service which have there, especially at critical joint streets and intersection streets, like Gatot Subroto - Cokroaminoto intersection roads. However progressively is fast accretion amount of vehicle, this method will not give optimal service, so that requires another way of problem-solving. Another Arrangement Alternative to solve this jam is with an intersection street is not at a piece of, such as which have been applied at Simpang Dewa Ruci. In general, the type of construction is fly over and underpass, but under experience at Simpang Dewa Ruci, from the social and cultural aspects happened deduction of fly over type. So that the study is limited to underpass type. According to the result of soil investigation at that location, the election of cheap type is boring pile construction with 60 cm diameter, reinforcement 14D22, U-40 steel and K-350 concrete, strung up with secant pile (bore pile without reinforcement and strength of concrete K-175). While the beam of the bridge is from reinforced concrete plate K-350 strength, 40 cm thick, reinforcement equal to 21,92 cm2, attached reinforcement by D22-15 (interesting side) and D22-30 (stressing side).
