The further improvement of the utility model is:

Every the tune inner curve is opened up in the left changing lane entrance.

In the pontic bottom, form the ring-type rotating disk concentric with the grade separation rotating disk.

Because the technological progress of having adopted technique scheme, the utility model to obtain is:

The utility model broken through existing overpass bridge keep straight on away straight way, turn the customary model of bend, overpass bridge and rotating disk principle are combined, the craspedodrome road is designed to the hook bend, enlarged the road space that crosses; Article four, the hook bend in craspedodrome road surrounds the grade separation rotating disk, and the crossing center space is vacated, and has realized that left changing lane distributes in optimal spatial; Make left changing lane relatively independent, and be arranged on grade separation rotating disk central authorities, make space performance maximum effect.

The three-dimensional hook arch bridge structure in craspedodrome road plays the effect that prolongs arch bridge length, grading, reduction pontic height.

Article four, the craspedodrome road interts each other, surrounds a grade separation rotating disk, and turnover independently of one another has avoided crisscross traffic and import and export to block up, and it is in good order to have realized coming in and going out.
