Prayagraj Bypass Expressway is an 84.708km (52.635miles) Controlled-access expressway located in the district of Prayagraj. It is the Asia's longest bypass in terms of length. The project is a section of National Highway 19. It forms the part of the Golden Quadrilateral, under the Kanpur-Prayagraj-Varanasi section of Delhi-Kolkata stretch. The primary purpose of construction was to reduce heavy traffic on the Grand Trunk Road through the city of Prayagraj.
The total work was divided into 3 contract packages. Construction of road from Km. 158 to 198 (except the Ganges Bridge) was taken up by the National Highways Authority of India with loan assistance from the World Bank.[1] The project consisted of 2.608 km of 4-lane widening of the existing NH-19 and 82.1km (51miles) of new construction. The Prayagraj Bypass takes off from 158km (98miles) of NH-19 (near Kokhraj), runs for 2km (01miles) along the existing alignment and then for 82.1km (51miles) along new bypass alignment, north of Prayagraj city.[2] It rejoins the existing alignment of NH-19 (near Handia) and runs another 0.608km (00.378miles) to end at 242.708km (150.812miles) (NH-19 stationing 245km (152miles)). A nearly kilometer long bridge on Ganga was also constructed as a part of the project
The four-laned bypass expressway has 5 exits, including the 2 terminals, that continue as National Highway 2 towards Kanpur and Varanasi. From geographically West to East, the exits are:
