Project overview

Before undertaking the development of the underpass, a model study of the traffic diversion plan was conducted to facilitate planning to meet every requirement of the project. Project planning called for the construction of an underpass with two bores, one for each direction of traffic or carriageway, with ramps of varying length. Two single span bridges were also to be constructed, one on each side of the main overpass. These bridges would allow traffic to take signal-free U-turns. During construction, a large number of traffic control signs and traffic police were placed at the intersection to guide drivers.[clarification needed]

Scope of work

The project involved construction of two bores of varying width along the Barket Market–Liberty Market Road. The underpass has on/off ramps of varying length, with

girders
. Service roads and slip roads have been provided at grade. A sump pump was installed on the Liberty-side ramp to prevent rain water from flooding the area of the underpass. Drains were made for its disposal.
