Teynampet-Saidapet flyover is TN's costliest at Rs 195 crore per km
Soil stabilisation, utility relocation jacked up cost Following the awarding of contract in November-December 2023, civil works of the project, executed by J Kumar Infraprojects, began in January 2024. The new four-lane elevated corridor aims to reduce the travel time between Teynampet and Saidapet on Anna Salai from 40 minutes to just 10 minutes, while easing congestion at seven key intersections — Eldams Road, SIET College Road, Cenotaph Road, Nandanam, CIT Nagar, CIT Nagar 1st Main Road (towards T Nagar), and Jones Road. This section of the arterial Anna Salai handles 2.45 lakh passenger car units per day. A senior highways official attributed the high cost of the Teynampet-Saidapet project to several critical factors such as soil stabilisation challenges requiring micro-piling (since shallow foundations prevented conventional piling), extensive utility relocations in a densely-congested area, and advanced construction techniques to minimise pillar loads and safeguard the underground metro tunnel. 'Soil stabilisation was achieved using geosynthetic materials like geogrids and geocells, among other solutions,' stated an official document released by the state highways department. The Teynampet-Saidapet metro line runs 17-18 metres beneath Anna Salai. The highways have drilled up to 7 metres from the road surface to lay the flyover's foundation. The elevated road spans 2.4 km directly above the metro line, including 460 metres over the Nandanam and Teynampet stations, and 655 metres along the non-metro stretch (excluding entry and exit ramps). In total, 69 pillars are being erected above the metro line, 22 on the non-metro stretch, and 41 portal frames covering the 460 metres over the two stations. As of July, about 30% of the work has been completed, according to official documents. Industry sources said NHAI projects, typically executed under Public-Private Partnership (PPP) mode, are usually more expensive than state highways projects, which are entirely government-funded. 'The estimation of state highways and NHAI projects are arrived at with an anticipation that materials, labour and other expenses will go up by 5% to 7% every year. By all measures, the cost of the state highways project ought to be lower than that of the NHAI unless it's being executed under exceptional conditions,' sources added. Even after accounting for inflation and price escalation, the proposed 18.5 km six-lane elevated corridor between Kilambakkam and Maraimalainagar, with entry and exit ramps at three locations, is estimated to cost Rs 3,450 crore, averaging Rs 188 crore per km. Likewise, two upcoming six-lane elevated corridor projects of NHAI – from Maduravoyal to Outer Ring Road and from ORR to Sriperumbudur, scheduled for award in 2025-26 – are projected to have an average cost of Rs 160 cr/km.

Decade later, SCLR extn iscomplete, but for load test
Mumbai: The SCLR extension is now structurally ready, with a final load test scheduled on the cable-stayed bridge over Vakola flyover before it is opened to traffic. MMRDA has completed the asphalting work on the final stretch of the Santacruz-Chembur Link Road (SCLR) extension. The elevated corridor includes a crucial cable-stayed span crossing the Western Express Highway (WEH) at Vakola. "The load test is scheduled for Tuesday, subject to dry weather. This is the final procedure before the bridge can be declared fit for traffic," said sources associated with the project, which is executed by J Kumar Infraprojects. A load test is an essential structural assessment where loaded vehicles or calibrated weights simulate real-world traffic conditions. It helps engineers measure deflection, strain, and vibration in the structure to verify if it performs as designed. A successful load test is mandatory before opening the bridge to the public. Due to sharp curves and elevation requirements to pass above the existing Vakola flyover, engineers opted for a cable-stayed design over traditional concrete girders. "The longer span and fewer piers made the design ideal for this tight corridor," a source involved in construction explained. The cable-stayed bridge is capable of handling more pressure compared to a suspension bridge. The 250-metre-long cable-stayed section includes an Orthotropic Steel Deck (OSD), known for being lighter and stronger than concrete decks. "It reduces the load on piers and speeds up construction," the source added. All 58 prefabricated steel segments, each measuring 4x10.6 metres, were manufactured at a workshop in Wada using E410-grade steel with corrosion-resistant paint. MMRDA also sought permission from the Maharashtra State Road Development Corporation (MSRDC) to install a temporary pier in the flyover median to assist with the deck launching. Work on the SCLR extension bridge started in 2016 and was scheduled to be completed in 2019. However, the absence of right of way and design issues, as well as the Covid-induced lockdown, led to an extension of the deadline.
