200 km+ 8 lane expressway to be built right beside the existing 4 lane Dhaka - Chittagong highway, comes with a full suite of modern facilities such as automated toll plazas, weighting bridges (to weigh trucks), and stop stations every so often with recreation area for travellers, restaurants, hotels and gas stations.
This project, in my opinion, will have a significant impact on the economy and the rate at which we are able to get the goods from the industrial cities strewn around Dhaka and Chittagong to the port itself in the shortest amount of time possible, thereby saving money and countless manhours.
Coupled with the new deep sea port being built at matarbari, the new bay terminal of CTG port and the CTG port itself which is in the process of expansion and upgradation, this express way will bring big dividends to Bangladesh and the region as a whole.
More than ¼ of the Bangladeshi population lives along the path between Dhaka and Chittagong, so it's not suprise to know that this project will have a huge effect on the economy.
Maybe not as much as the overhyped Padma Bridge but it will nevertheless be up there.
More importantly, it will put an end to traffic jams on the Dhaka Chittagong highway and ensure smooth travelling between Dhaka and Chittagong, making it future proof for atleast the next 2 decades by when there will be ports based outside the Chittagong region.
Because upgrading the existing highway every 5 years is unsustainable, this project will not only remedy that issue but completely bypass it.
Here is the Roads and Highways Department's animation of the whole project, Imo the most important project undertaken apart from Padma bridge, :
