The grade separator is designed for central elevated rotary of area 4250sq.m, with inner radius of 18.5m and outer radius of 41.0m. The rotary is designed with solid slab due to its complex shape and curvature. The connecting elevated road consists of two/three span continuous modules with 30m/40m spans having uniform depth of 2.0m. The structure is integrated with piers resting on pile foundation. The complex analysis has been done using commercial software MIDAS Civil.
