The alignment will run from Angamaly in Ernakulam district to Aroor in Alappuzha district and is expected to cover about 50 km following the decision to extend the route southwards. Earlier proposals envisaged an Angamaly–Kundannoor corridor of around 44.7 km, but updated network planning and revised traffic projections prompted the extension to Aroor. The revised route is being designed to link directly with the Aroor–Thuravoor elevated highway that is currently under construction, creating a continuous high?speed travel corridor.
The National Highways Authority of India (NHAI) has initiated preparatory work, including surveys and alignment studies, and has introduced Continuously Operating Reference Stations (CORS) technology to accelerate field investigations and support land acquisition. Officials said the technology will improve positional accuracy and shorten survey timelines, which should expedite initial implementation phases. The project is being aligned with the PM Gati Shakti National Master Plan and is being developed as a greenfield highway to meet strategic mobility objectives.
Planners expect the bypass to divert a substantial share of long?distance traffic away from urban sections such as Edappally, Angamaly and Aroor, thereby improving travel efficiency for freight and passenger movements and reducing pressure on existing corridors. Authorities have considered options to increase the highway's capacity in response to projected future demand and to ensure integration with other ongoing national highway upgrades in Kerala. Completion timelines and detailed cost estimates will be provided as project studies progress.
