摘要: |
The new corridor between East and West Godavari district starts at km 81/349 of Eluru-Gundugolanu on Kovvurside (West Godavari side) and ends at NH-5 at km 903/337 Rajahmundry side. The corridor has total length 14,488 km comprising of a completely new alignment which consistsof twoparallel major bridges of 4.088 km long & 2 lane each. The approach road to the bridge on west Godavari side(Kowur Side) is about 1.968 km in length, while that on east Godavari side(Rajahmundry side) is around 8.432 km in length. For this 50.0 m long span bridge instead of using preferred well foundation for river bridges, large size pile foundations were chosen and also initially conceived 6I' beams were changed to precast segmental box girders to reduce the time of construction. On the other hand, Kosi River Bridge of 1.8879 km in the state of Bihar on the new alignment of NH-57 between Darbhanga and Forbesganj is a single four lane box girder bridge with the span of 48.15 m instead of two parallel two lane carriageway bridge. The approach road to the bridge on Darbhanga sideis about 5.5525 km in length, while that on Forbesganj sideis around 3.20425 km in length. For this 48.15 m long span bridge conventional well foundations were chosen. In the detailed paper while design and construction aspects are deliberated for these two bridges on PPP model, the necessities and economics of having single four lane carriageway bridge vis-a-vis two parallel two lane carriage way bridges is discussed at length. |
