Nagpur’s Public Works Department has estimated that 490 precast concrete blocks will be needed for a proposed Rs3 crore experimental road in Mhalgi Nagar, with the project designed to address waterlogging and the elevation mismatch that often leaves adjoining homes and plots lower than newly built cement roads.
The two-lane road will stretch for 330 metres and have a width of 7.5 metres, according to the PWD estimate. Each block will measure 2.5 metres by 3.7 metres and have a thickness of 0.2 metres. The department is expected to begin work after completing the necessary formalities.
PWD officials told The Times of India that the road will be designed to match the surrounding ground levels. The stated objective is to avoid the excessive elevation that can occur when conventional cement roads are built over existing surfaces. Such elevation differences can obstruct access to nearby properties and allow rainwater to flow towards houses and plots.
The project will use concrete elements cast in advance and assembled at the site. This differs from conventional cement road construction, in which concrete is laid at the location and allowed to cure before the road can be used. The PWD expects the precast method to reduce the time required for construction and limit disruption to traffic and access along the road.
The Mhalgi Nagar stretch will serve as a trial for the department to assess whether precast concrete technology can be used on a busy urban road. The experiment will also test whether factory- or yard-cast blocks can provide greater control over the finished road’s elevation than construction carried out entirely at the site.
Road height has become a practical concern in neighbourhoods where successive upgrades can raise carriageways above adjoining plots, entrances and houses. While the PWD has linked the proposed design to reducing waterlogging and preventing rainwater from entering homes, the project’s effectiveness will depend on how accurately the assembled blocks meet existing levels and connect with surrounding streets and properties.
The estimated 490 blocks will cover a relatively short urban road, making the project a defined test rather than a city-wide construction programme. Its outcome could help the department determine whether the method is suitable for similar roads where construction speed, access and finished elevation are significant concerns.
The project remains at the planning stage. The PWD must complete the required formalities before work begins, after which the Mhalgi Nagar road will provide the department with an opportunity to assess the construction method under local traffic, drainage and site conditions.
