The construction of an overhead crossing at an intersection aims to ease traffic congestion in an urban area. However, traffic congestion tends to worsen during the construction period that takes one to two years by a conventional construction method. The people living in the vicinity are forced to put up with the inconvenience. A breakthrough technology has long been desired for overhead crossing construction, which will quickly realize the economic effect and lessen the burden on the environment without bringing inconvenience to the neighborhood. We have developed a construction method of an overhead crossing called "SMArt Crossing" in cooperation with Asanuma Corporation in order to solve the potential problems involved in conventional construction.
The features of the new construction method are:
1) A right turn lane is secured to avoid traffic congestion during a construction period.
2) The construction period is reduced to four months.
3) The construction of an overhead crossing at an intersection is implemented overnight.
