In 2022, National Highway Authority of India allocated to redevelop 318km (198miles) of the highway into wide 4 lanes. The highway was expected to be completed by 2024.[2] However, land acquisition related issues at various places is causing the delay for the project by several years.
In February 2024, in reply to an RTI, NHAI informed that the DPR of this highway is yet to be completed and no indicative period for the commencement and completion of the project was informed.[3]
