The Mumbai–Nagpur Expressway or Nagpur–Mumbai Super Communication Expressway (officially known as Hindu Hrudaysamrat Balasaheb Thackeray Maharashtra Samruddhi Mahamarg) is an under-construction 6-lane wide (expandable to 8), 701 km long access-controlled expressway in the state of Maharashtra, India.
SYSTRA completed the detailed design work for the Package 2 of the Access Controlled Nagpur-Mumbai Super Communication Expressway Project, located in the state of Maharashtra. The Expressway connects the capital city of Mumbai to the city of Nagpur, which is the third largest city and the winter capital of the state.
Key features of the project
- 58.41 km long Six lane access control expressway with 150kmph Design Speed
- Total 153 major and minor structures on this project section. Few important structures are
- Viaduct with 80m span Bow String Steel Girder over existing State highway and river
- Major bridge of 315m total length with 3 & 4 span deck continuity for 31.50m span length and average 30m height of Piers
- India’s 1st Wildlife Overpasses with span arrangement of 2×20.60m + 2×31.05m, overall width 45m and average 30m height of portal type piers
- Elevated Rotary at Interchange with deck continuity
As a part of Value Engineering exercise and to optimise material requirements, the team made a detailed comparison of Tender vs. Detailed Design quantities for each type of material used in the design phase. Substantial optimization of cutting slopes was proposed in design to reduce overall construction footprint. As a result of this exercise, materials optimisation was achieved up to 8.5% on the overall civil construction cost.
The expressway crosses a major ecological zone in which the Wildlife Institute of India has identified Wildlife Focus Areas (WFA). A big effort is being made in this direction to ensure that the project is a model for wildlife protection and conservation. As a part of this initiative, additional wildlife overpasses and underpasses were proposed, allowing safe passage for animals to minimise the disruption. The project also includes a huge tree planting programme along its length.
SYSTRA team received a recognition award from the client for their exemplary services in the design and support during execution.
