6/8-lane highway. The reason cited by the State Government was the difficulty and disinterest in Land Acquisition, which is the responsibility of the State Government. NHAI had stopped working on many of the highway widening/upgrade projects as there are opposition from the local population for highway widening. Among Kerala's districts, Ernakulam has the maximum length of National Highway, which accounts for 172.76 km. Wayanad has the minimum length of National Highway in Kerala. Government has taken steps to develop the NH 66 (Kasargod to Thiruvananthapuram) into six lane. But, proposed six lane highways with 45 m Right of Way in Kerala will not have the wide medians to help the trucks and large vehicles to take the U-Turn without blocking the high speed traffic, which is a common feature in other parts of India.

Six-laning of National Highways in Kerala Kerala's first six lane National Highway is coming up on the NH 544 between stretches of Thrissur and Vadakkencherry.

Keeping in view a futuristic approach, it has been decided that the land for any 4/6-lane highway road will be acquired with a right of way (RoW) of 60 m irrespective of the width of the carriageway. Kerala has not been allocated Greenfield 8-lane access-controlled expressways like other south Indian states as part of Bharatmala Pariyojana, as many brownfield projects of NHDP projects have still not started. The Palakkad—Thrissur—Kochi stretch of NH 544 is a part of North-South and East-West Corridor of the Indian highway system. Due to the previous land acquisition crisis, NHAI had also stopped the feasibility study of the project under NHDP–Phase-III scheme in the stretch of NH 66 earlier, but has begun again after the strict demand of present Chief Minister. There was a proposal for construction of standalone ring road/bypasses around Tiruvananthapuram City under NHDP Phase VII. State highways There are 72 state highways in Kerala.
