The political temperature soared at the Maharashtra Legislature complex on Wednesday as opposition parties launched a sharp attack on the BJP-led state government, alleging irregularities in the scrapped Thane-Borivali twin tunnel project and linking it to a ₹3,000 crore scam.

Leaders from the Maha Vikas Aghadi (MVA) — including Shiv Sena (UBT), Congress, and NCP — staged a protest on the steps of the Vidhan Bhavan, accusing the government of favouring a private firm closely tied to the ruling establishment. They demanded a full investigation into the now-cancelled tender process.

The controversy centers around the Mumbai Metropolitan Region Development Authority’s (MMRDA) decision to cancel the tender for the high-value infrastructure project earlier in May. The move followed legal proceedings after construction giant L&T was disqualified and subsequently approached the Supreme Court.

Opposition legislators claimed the cancellation was not due to public interest but a strategic retreat to avoid court scrutiny. They alleged that Megha Engineering and Infrastructure Ltd — seen as the “preferred contractor” — received special treatment despite conflict-of-interest concerns.

Congress leader Satej Patil and NCP’s Jayant Patil raised red flags over transparency, pointing to the company’s reported donations through electoral bonds as evidence of proximity to the ruling party. Patil demanded a reassessment of all contracts awarded to the company, stating that such links undermine public trust in the tendering process.

Shiv Sena (UBT) leader Ambadas Danve declared that the opposition would keep the issue alive inside and outside the legislature until the government addressed questions about the project’s integrity. Protesters held placards that read “Contractor First, Farmers Last,” symbolizing their charge that the government prioritizes corporate interests over public welfare.
