The project corridor is a part of Patna-Gaya National highway 83. The elevated corridor will serve as a through link to Gaya, which is one of the crowded Pilgrimage centres of India & help in decongesting traffic in Patna city.
The project features 5km long elevated corridor constructed using Precast segmental box girder of 45m typical span length. Spine and wing shaped single cell box girder is proposed for 17.2m deck width. The project alignment runs parallel to railway track on one side and features a ROB downramp for traffic towards Sipara.
Due to weak subsoil strata, pile length of upto 55m is proposed at certain locations. The project also includes multiple minor bridges and box culverts for at-grade road.
