The Lucknow-Azamgarh-Ballia- Expressway now renamed as Purvanchal Expressway is an under construction 6-lane, divided and access-controlled highway, in India's Uttar Pradesh state. The expressway will connect the historic towns of Ballia and Azamgarh with the state capital, Lucknow. It is to be developed by the Uttar Pradesh Expressway Industrial Development and Authority.
The project will be executed by Gayatri Projects, Apco Infratech, GR Infra, PNC Infratech and Oriental Structural Engineering. The total project has been divided in 8 packages, with Gayatri Projects, GR Infra and PNC Infratech allotted 2 packages each and Apco Infra and Oriental being awarded one package each. The easy bidding process has also resulted in 10% cost reduction for the project.
It will be about 400 km long expressway and will connect Lucknow to Ballia by passing through 10 districts: Barabanki, Sultanpur, Amethi, Faizabad, Ambedkar Nagar, Azamgarh, Mau and Ghazipur. It will terminate in Ballia. The expressway is to be linked with Varanasi-Gorakhpur highway through a separate link road.
The 400 km project was conceptualized by the previous Samajwadi Party government in early 2015 as 'Samajwadi Purvanchal Expressway'. After coming to power in March 2017, the BJP government dropped the word 'Samajwadi' from its name and retained the project which was to pass through Lucknow, Barabanki, Amethi, Sultanpur, Faizabad, Ambedkar Nagar, Azamgarh, Mau and Ghazipur to reach Ballia. The total cost of the project was initially proposed as ₹15,000 crores but the new bidding after Yogi decreased the proposed costs to ₹11,000 crore.
