Andhra Pradesh has proposed a ₹20,369 crore plan to widen busy two-lane national highways into four-lane roads. The proposal covers around 446 km and has been sent to the Union Ministry of Road Transport and Highways for consideration.
The state has prioritised routes carrying more than 10,000 Passenger Car Units (PCUs) a day. Officials are expected to finalise road alignments and prepare Detailed Project Reports (DPRs) by March.
The Kadapa to Tamil Nadu border highway is estimated to cost ₹3,100 crore, while the Palamaner to Krishnagiri route may require ₹2,250 crore. The proposed expansion of the Akividu to Digamarru highway is estimated at ₹2,709 crore, while the Gudivada to Hanuman Junction road project is estimated at ₹1,300 crore.
The Kadapa to Tamil Nadu border stretch covers more than 150 km and reportedly carries around 13,000 PCUs daily. Another proposal involves a 7.5-km tunnel through the Gollavagu Cheruvu Ghat section between Kadapa and Rayachoti, estimated to cost ₹940 crore. Further studies and forest and wildlife clearances are needed before it can proceed.
The government has also proposed widening the 48.37-km Muddunur to Kadapa highway, estimated at ₹1,900 crore. In Chittoor district, the approximately 90-km Palamaner to Rayapanoor stretch is also proposed for four-laning.
In the coastal region, the 38.46-km Gudivada to Hanuman Junction road is proposed for four-laning, along with a Gudivada bypass. The 39.57-km Akividu to Digamarru highway is also part of the plan. The Centre has sought concessions on mining charges for gravel and crushed stone, as well as state GST concessions on cement and steel for the Akividu project.
The Amalapuram to Ravulapalem road, covering around 31.90 km, is estimated to cost ₹720 crore. A decision on four-laning or retaining a wider two-lane road is still pending, with traffic volume among the factors being considered.
The proposal also covers other roads, bypasses and road-over-bridges. All projects are subject to approvals, detailed planning, clearances and funding decisions.
If implemented, the plan could reduce congestion, improve travel between Rayalaseema and coastal Andhra, and strengthen links between towns, industrial centres and major highways.
