<p>The Karnataka Road Development Corporation Ltd (KRDCL), a company under the Public Works, Ports and Inland Water Transport Department that was established to promote surface infrastructure by taking up road Works, construction, and redevelopment of bridges, has recommended strengthening these bridges, a majority of which are in use.</p>.<p>The state government had directed the KRDCL to prepare a detailed feasibility report (DFR) on the status of bridges, as per the announcement made during the 2022-23 budget session. “We prepared the report and submitted it to the government about three months ago,” a senior official told <em>DH.</em> “But the government is yet to approve the budget.”</p>.<p>While some of these bridges are closed to vehicles, others remain open, officials said.
