The work on the Colaba-Seepz metro is set to get delayed further as the implementing agency MMRDA has re-invited bids with modification to attract competitive bidding.

The government had earlier planned to commence work on the around Rs 24,000-crore underground metro project by January. However, due to certain issues raised by bidders on the eligibility criteria, the Mumbai Metropolitan Region Development Authority (MMRDA) re-invited pre-qualification bids with certain modifications.
