Blackspot TN-03-300 on the Kayathar to Kanyakumari section of NH-44 is to be removed for good with a vehicular underpass at km 208.900, and the ₹47.63 crore Kayathar underpass tender closes at 11:00 AM on 13 November 2026.
Underpass, service roads and a bridge
NHAI describes the work as permanent rectification of the blackspot by building a vehicular underpass at km 208.900 with service roads on both sides, plus reconstruction of a minor bridge and its service road on both sides. It is an EPC contract.
The Regional Officer at Madurai is the inviting authority, and the reference is NHAI/17011/01/159/2026/RO Madurai. The contractor gets 365 days, which is quick for an underpass built under traffic.
A higher deposit than usual
EMD is ₹96,00,000, about 2 per cent of the estimate, with no exemption. The fee is ₹10,000. A pre-bid meeting is set for 11:00 AM on 23 October at the Madurai regional office. Bids open at 11:00 AM on 14 November 2026.
With a single location and a one-year clock, the job turns on sequencing. A diversion goes in first, built by a motor grader and rollers. Excavators then open the underpass cut, a crane places precast box segments or girders, and transit mixers serve the walls and the bridge. Service roads are paved last. Machine owners in Tirunelveli and Thoothukudi districts are within easy reach.
