The
650m long road overbridge is provided to cross four broad gauge
lines and two road crossings.
The bridge consists of two 8m wide (2 lane) independent
carriageways (10m wide overall) with 1m wide kerb and parapet
construction on either side.
These are separated by a gap of 6m. Provision is made in
the design to build a separate carriageway in between, so that
eventually it becomes a 6 lane, 24m wide carriageway (26m
overall).
The
bridge portion consists of reinforced concrete slabs spanning
13.2m monolithic with reinforced concrete piers resting on open
foundations. This
structural system has been adopted to enable faster construction
and a shallower super structural depth (only 650mm). |
