National Highways Authority of India (NHAI) has called an RFP tender for the improvement & upgradation of the existing two lane Hubballi-Dharwad bypass to six lanes to be executed through an Engineering, Procurement and Construction (EPC) contract.
Bypass as a city road
Hubballi-Dharwad Twin Cities – one of the designated smart cities in Karnataka, look to be coming out of the slumber in order to catch the fast train towards growth. The existing inefficient/ creaky infrastructure is being replaced with modern 21st-century ones with state-of-the-art digital equipment to ensure optimization. One of such projects is the expansion of the Hubballi-Dharwad bypass road to six lanes with a digital tollbooth to collect and consolidate tolls with ease at a jiffy.
The project is explained in brief in the following pages
Project in brief
The present two lane Hubballi-Dharwad bypass is all set to be expanded to six lanes with service roads. NHAI has decided to establish a single toll beyond Kelegeri while doing away with the multiple tolls between Hubballi & Dharwad. This means the stretch between these cities would remain toll free, thereby helping the residents to commute quicker & for free. Old PB road which connects Hubballi & Dharwad cities is saturated already. Opening up of the 6-laned bypass to city traffic would provide the much needed capacity to cater to future traffic. Bypass can emerge as an economic corridor with planned Integrated townships promoting the concept of “walk to work”.
