Hyderabad certainly has reason to celebrate! The newly constructed Durgam Cheruvu cable-stay bridge eases traffic and reduces commute time. What?? more, it has set a record for being the world?? longest precast segmental span of 233.85-m in concrete on a cable-stay bridge. Constructed under Telangana?? Strategic Road Development Programme, and recently inaugurated by KT Rama Rao, Minister of Municipal Administration & Urban Development Industries, IT&C, Telangana, the construction of the bridge was completed by Larsen & Toubro (L&T) and it was dedicated to the people of the city.

??ur association with this young state of Telangana has been rich and we are proud to have delivered yet another pearl to the City of Pearls,??says SN Subrahmanyan, Chief Executive Officer & Managing Director, Larsen & Toubro. ??nfrastructure development should ultimately improve the life of citizens and this bridge will certainly improve connectivity within the city of Hyderabad manifold. We are also grateful to the Telangana Government for having reposed their faith in us once again to deliver world-class infrastructure once again. And we are happy to have delivered to their complete satisfaction.??/p>

Speaking on the USP of the bridge, SV Desai, Whole-Time Director & Senior Executive Vice-President (Civil Infrastructure), L&T, elaborates, ??t has the world?? longest precast segmental span of 233.85-m in concrete for a cable stay bridge. We have constructed it despite extremely challenging conditions and terrain using a total of 428 mt of high-tensile strand, 26,600 cu m of concrete, 4,800 mt of steel and 287 mt of stay cables. We are happy we delivered the project in time even during these unprecedent times of the pandemic.??/p>

While the entire bridge with its approaches at both ends is 764.38 m, the cable-stayed bridge portion is 435-m long and 25.8-m wide with a total of 52 stay cables. The 53 CC (cement concrete) segments of the bridge are supported by stay cables sourced from Germany. The approach viaduct and solid ramps are 309.8-m long with 1.8-m wide footpaths on both sides.

Hyderabad is another Indian metro notorious for its traffic and this bridge will ease traffic flow towards HITEC City. Studies have revealed that the average time taken to reach the ITC Junction from Jubilee Hills (Road No. 45) is anywhere between 25 minutes and 30 minutes. The Durgam Cheruvu bridge will reduce commute time from Jubilee Hills to Madhapur from 30 minutes to a mere 10 minutes and the distance from Mind Space to Jubilee Hills by 2 km.

Why an extradosed cable-stay bridge?

An extradosed bridge is a cross between a girder and a conventional cable-stayed bridge, wherein the deck is directly supported by the pylon and the tension of the cables acts more to support it vertically. The cable stay acts as a prestressing cable for the concrete deck. Hence, the deck is comparatively thinner and the span length more in an extradosed bridge. Precast engineering has significantly reduced execution time and costs.

The world?? longest precast segmental span

The bridge has the world?? longest precast segmental span of 233.85-m in concrete for a cable-stay bridge. Although extradosed bridges are commonly constructed using the balanced cantilever erection method, in this case, a back span was constructed with complete staging from the ground and then the main span was constructed by cantilever erection with precast segment using a derrick crane.

Speedy construction

The precast segments were made ready by the time the anchor spans were casted in-situ, which speeded up construction. Precast segments of 3.5-m length and weighing 155 tonne were cast or fabricated in a casting yard and transported to site for erection while the derrick crane was designed and fabricated by L&T.

Challenging conditions and terrain

The bridge has been constructed in extremely challenging conditions and terrain with a lot of the work happening at 20-m above ground or above water. Executed within contractual stipulations, the 4.7-m depth of the precast elements was a challenge as was the task of transporting the huge precast elements from the casting yard through the busy, round-the-clock traffic near the site and erecting them at site. A unique aspect of the project was the casting yard that was synchronised with a load-out jetty that substantially reduced cycle time.

The bridge is equipped with aesthetically pleasing, first-of-its-kind carriageway lighting and will be a major recreational and tourist attraction for citizens with its specially designed footpath. Apart from the cables and the lighting system, everything else has been sourced from India making this bridge a shining example of the ??ake in India??movement.

Shares

The Cyberabad Traffic Police issued a traffic advisory as road works begin for the laying of a cement concrete (CC) road from Jaya Shankar Statue to RRR Restaurant at Parvathnagar in Madhapur limits. The advisory indicated that traffic diversions will be in place for 30 days from May 16 to ensure the smooth flow of vehicles and to minimise congestion on the affected stretch. The measure aims to balance uninterrupted construction activity with the movement needs of commuters.

Traffic moving from Toddy Compound towards Parvathnagar village will be diverted at Parvathnagar junction towards Sunnam Cheruvu and the 100 feet road. Local motorists and public transport operators have been advised to follow the diversionary route as directed by traffic personnel on duty. Alternate routes and signage have been planned to mitigate delays and to manage peak hour congestion.

Police officials said the diversion had been planned to facilitate uninterrupted road works while maintaining traffic movement in the area. Commuters were urged to plan their travel accordingly and to cooperate with traffic staff managing the stretch. Authorities indicated that enforcement of diversions would be active and that violations could attract penalties.

The 30 day schedule is intended to allow contractors to complete the laying and curing phases with minimal interruption to vehicular flow. Residents and businesses in adjacent localities have been advised to factor the diversion into deliveries and travel plans. The traffic police promised continuous monitoring of the works and the operational diversions and emphasised that temporary inconvenience was necessary for longer term improvement of the road network. Traffic personnel will be stationed at key junctions and additional signage and temporary markings will be displayed to guide motorists and pedestrians through the revised alignments while public transport services will follow the diversion where feasible and operators have been asked to adjust timetables to minimise disruption.

HeidelbergCement India (HeidelbergCement India) has received regulatory consent to establish a cement blending and grinding unit at Village Dongaliya, Tehsil Punasa, District Khandwa in Madhya Pradesh. The consent was granted by the Madhya Pradesh Pollution Control Board under the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981 and is dated 17 May 2026. The company disclosed the development in a filing made under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

The project plan envisages procurement of long term availability of fly ash and the allotment of land on lease for setting up the unit. The proposed facility is described as a blending and grinding installation which will process cementitious materials sourced from nearby operations and suppliers. Company filings state the measures required to secure raw material logistics and statutory compliance before commencing construction.

The addition of a grinding unit in Khandwa is intended to strengthen regional supply and improve logistical efficiency by reducing haulage distances for finished product. The unit is expected to complement existing capacities in central India and to offer flexibility in product mix through blending operations. The reliance on fly ash as a supplementary cementitious material will necessitate long term supply agreements with thermal power producers and coordination with waste utilisation policies.

The disclosure to the regulator and to the stock exchanges follows standard corporate governance practice and aims to keep investors apprised of capital expenditure initiatives. The company indicated that subsequent permits and clearances would be sought in accordance with applicable environmental and land use rules. The project is presented as part of HeidelbergCement India’s broader strategy to optimise capacity distribution and to respond to regional demand dynamics.

The new solution promisescontinuous, real-time tertiary air flow measurement in cement plant operations.

PROMECON GmbH has launched the McON IR Compact, an infrared-based measuring system designed to deliver continuous, real-time tertiary air flow measurement in cement plant operations. The system addresses the longstanding process control challenge of accurate tertiary air monitoring under extreme kiln conditions. It uses patented infrared time-of-flight measurement technology that operates without calibration or maintenance intervention.

Precise tertiary air measurement is a critical requirement for stable rotary kiln operation. The McON IR Compact is engineered to function reliably at temperatures up to 1,200°C and in the presence of abrasive clinker dust. Its vector-based digital measurement architecture ensures that readings remain unaffected by swirl, dust deposits or drift. Due to these conditions conventional measurement systems in pyroprocess environments are often compromised.

The system is fully non-intrusive and requires no K-factors, recalibration or periodic readjustment, enabling years of uninterrupted operation. This design directly supports plant availability and reduces the maintenance overhead typically associated with process instrumentation in high-temperature zones.

PROMECON has deployed the McON IR Compact at multiple cement facilities, including Warta Cement in Poland. Plant operators report that the system has aided in identifying blockages, optimising purging cycles for gas burners, and supplying accurate flow data for AI-based process optimisation programmes. The practical outcomes include more stable kiln operation, improved process control, and earlier detection of process disturbances.

On the energy side, real-time tertiary air data enables reduction in induced draft fan load and helps flatten process oscillations across the pyroprocess. This translates to lower fuel and energy consumption, fewer unplanned shutdowns, and a measurable reduction in NOx peaks. This directly reflects on the downstream cost implications for plants operating SCR or SNCR systems for emissions compliance.
