A left-turn ramp will be added to the flyover, which was completed at a cost of Rs 15 crore in 2007. It is a unidirectional flyover on which cars move from Hastings towards Karl Marx Sarani. The flyover ends 50 metres before Fancy Market.

"Traffic plies in both directions on the old road on the ground, leading to Kidderpore Bridge, which is narrow. Although most bridges and flyovers have four lanes of seven metres each, the Kidderpore bridge has only three lanes. All cars, moving from Hastings towards Diamond Harbour Road, take the bridge since the newly built flyover accommodates vehicles beyond the Karl Marx Sarani-DH Road crossing," said a senior official of Hooghly River Bridge Commissioners (HRBC), the agency that built the flyover.

The width of the bridge's carriageway is less than what is needed to accommodate large vehicles. Once the ramp is constructed, "the two-way vehicular movement will be segregated", added the official.
