The concreting of shabby service roads adjacent to both highways is part of a larger project to concrete the entire Western Express and Eastern Express Highways in phases over the next few years. The service roads will serve as additional lanes for heavy vehicles and facilitate access to the main carriageway, according to reports.

The Brihanmumbai Municipal Corporation issued a tender on September 23, with an estimated cost of Rs 1,591 crore to concrete approach roads totalling 44 km in length that connect both highways to major and minor roads in the city. Although there is debate over whether to concrete service roads, which are less utilised than main roads and often trenched due to utilities underneath, it is revealed that the concreting of service roads is not the ultimate goal but rather the initial step in the larger project to convert both highways into concrete roads.
