Plane line position of road will be arranged along the original road network of old city in UIGE, In order to avoid relocating buildings at both sides of road, the center line of road will almost coincide with the center line of original road. In all roads, only the center line of the U08 road starting from roundabout is different from original road, and other roads are without realignment. The radius of curb at intersection will be reasonably set according to road grade during plane design.
The road cross section design will be determined according to the cross section of original roads in old city of UIGE, and the positioning of the boundary line of design cross section will avoid relocating buildings at both sides of road.
Cross Slope: The cross slope of vehicular road will be 2.5% from inside to outside; and the cross slope of sidewalk will be 2.0% from outside to inside.
