The NHAI has received the approval to upgrade the complete stretch of highway, from start to end, to a four-lane highway, which will be and grade separated. Out of four states through which the highway goes, Karnataka and Maharashtra have received approval from the centre for the wide highway. Kerala and Goa have requested a narrower width of , and there are protests against the highway being widening in these states. The four-laning of NH-66 (Mumbai-Kanyakumari) has been completed until Thalapadi in the Karnataka-Kerala border and only its stretch in Kerala is pending. In the beginning of 2017, Kerala government has announced the six laning of NH 66 in the state as a major agenda and said to be completed in three years. But the high value of land will make it hard for compensation, and the ruling party's influence is controversial in relation to similar acquisitions like GAIL pipeline. Now the process is going fast in spite of protests from various highway action forum groups, especially because it connects Kerala's capital

and of tourism importance. NH 66 has one of the highest vehicle densities in the state compared to sections of the highway in other states, so its development is vital for the overall development of the state, also the HAM model to be followed in widening will be instrumental in collecting the funds for the development. NHAI has been infamous for their heavy and long tenure of toll collection in the state. Till now stretch out of long National Highway 66 (NH 66) have been made into four-lane highway. Karnataka and Maharashtra are widening to six-lane & stretch out of long National Highway 66 (NH 66) have been made into six-lane highway. Tunnels will be constructed in the stretches where the road goes through the forest or ghat section. As the forest department does not allow land acquisition for road widening purposes, tunnels which can accommodate four-lane expressways are proposed for such stretches of the road in NH-66. One such proposal is the Maharashtra government's proposal of 1.4 kilometre tunnel at the Karnala bird sanctuary. Currently, the road is comparatively narrow and without dividers for the most part. The lack of dividers has led to an increased incidence of head-on collisions between vehicles. At some places, signboards indicating left or right turns, speed-breakers, etc. are either damaged or missing. In addition to its narrow span, there are no guard railings along the sides of the highway. The sides of the road are at times at a lower level than the road. Due to heavy human settlement around the highway and narrow span, the average speed on this highway is far lesser than what can be attained on comparatively better highways such as NH3, NH4 or NH8. One can find carcasses of animals on the road, indicating the risk of inattentive animals coming into the road. Two-wheel vehicles must take a special note of this. The road surface is uneven at certain stretches, not just in rainy seasons, but even at other times. At certain places in Karnataka, the surface is so badly damaged that the iron rods underneath are exposed. Presently, the work on widening this highway has been undertaken at certain stretches. Due to narrow span and lack of dividers, there are no separate lanes for oncoming traffic, driving and passing (over-taking). As a result, over-taking is quite rampant. At times, motorists attempt over-taking even on curves where the oncoming traffic cannot be seen. Other motorists are advised to be on the lookout for such oncoming vehicles. On 19 March 2013 a bus carrying over 50 persons fell off a bridge close to a river in the Khed area of Ratnagiri district. 37 people were killed in the incident. The highway in the state of Karnataka is being upgraded to a 60-metre-wide grade separated highway, in which vehicles can travel at a speed of 100 km per hour. It is a major overhaul, in which certain bridges are being constructed as six-lane bridges for the smooth movement of traffic. The widening work is going on in the complete stretch from the Goa border to the Kerala border. The stretch between Suratkal (NITK) to Kankanady cross (Mahavir Circle) has been already converted to four lanes. The four-lane stretch between Surathkal and Coondaapur is under progress.

s and arecanut gardens. The road is uneven, and bumps, curves, steep rises and narrow paths in between hillocks are found all over this highway. As this region experiences heavy rainfall, potholes are abundant. Although the languages spoken vary along the highway, the food of the people along the NH 66 has some common ingredients like coconut, chili, pepper, coconut oil, and fish. The region has a higher literacy rate than other regions of India. The building of National Highway 66 has led to rapid development of the towns and cities along the highway.


Parallel access controlled expressway

This highway is expected to lose importance in coastal Karnataka as the Ministry of Road Transport & Highways, Government of India has proposed a greenfield (i.e., new and parallel) access controlled expressway corridor connecting the port cities of Mangaluru, Karwar, and Panaji. This highway-expressway combination can be compared to the Mumbai-Pune Highway-Expressway combination. Two-wheeler, three-wheeler and local traffic will use the four-lane highway (without access control and designed for slower traffic), whereas trucks, buses and four-wheelers will travel at the maximum speed on the access-controlled 3D right-of-way designed 6/8-lane expressway. (The 3D right-of-way concept means adding the space (height) element to the usual length and breadth dimensions involved in road construction.)
