India’s road infrastructure is entering another major phase in the final quarter of 2026, with several National Highways, expressways and economic corridors expected to reach important construction milestones between October and December 2026.
From the Delhi-Mumbai Expressway and Raipur-Visakhapatnam Economic Corridor to the Delhi-Amritsar-Katra Expressway and major Gujarat highway projects, these corridors are designed to improve long-distance travel, freight movement and connectivity between industrial centres, ports and major cities.
According to the Ministry of Road Transport and Highways (MoRTH), 10,389 km of National High-Speed Corridors have been awarded across India, with 4,809 km completed and 5,580 km under implementation as of July 2026.
Here is a look at some of the major highway projects to watch during Upcoming Highway Projects in India 2026.
1. Delhi-Mumbai Expressway
The Delhi-Mumbai Expressway remains one of India’s largest highway infrastructure projects. The approximately 1,386-km access-controlled corridor is being developed through Delhi, Haryana, Rajasthan, Madhya Pradesh, Gujarat and Maharashtra.
A major milestone is expected in the final quarter of 2026. A July 2026 report said the MP-Gujarat border to Vadodara section of around 148 km was scheduled to become operational by October 2026, which would bring the operational Delhi-to-Vadodara route to around 912 km.
The full project has faced package-wise delays, so the October milestone should be understood as a scheduled/expected opening rather than a guaranteed final completion date.
Why it matters
The expressway is designed to substantially reduce travel time between Delhi and Mumbai and provide a high-speed route for passenger and freight traffic.
The Gujarat sections are particularly important for connectivity between Vadodara, Surat, Bharuch and Mumbai-region industrial areas.
2. Vadodara-Mumbai Expressway: Gujarat Sections
The southern Gujarat portion of the Delhi-Mumbai Expressway is another important project to watch. The Kim-Ena section of about 36 km and Gandeva-Ena section of about 27.5 km were dedicated to the nation in June 2026.
Additional packages are still being developed. A September 2026 report said NHAI invited bids for balance work on the 35.4-km Jujuwa-Gandeva section, with an estimated cost of about ₹1,475.68 crore. The bid submission deadline is October 13, 2026.
This means October–December 2026 will be an important construction and contracting period for the remaining Gujarat stretches.
3. Raipur-Visakhapatnam Economic Corridor
The Raipur-Visakhapatnam Economic Corridor is one of the major greenfield highway projects expected to reach a significant milestone by the end of 2026.
The corridor is approximately 465 km long and passes through:
- Chhattisgarh
- Odisha
- Andhra Pradesh
The project has an estimated cost of ₹16,482 crore. According to a Ministry of Road Transport and Highways release, the corridor is expected to be completed by December 2026. It is projected to reduce the existing route from around 597 km to approximately 465 km and potentially reduce travel time substantially.
The corridor is important for connecting central India’s industrial and mineral-producing regions with Visakhapatnam and its port infrastructure.
Important note
The December 2026 date is a project completion target. It should not automatically be interpreted as a confirmed date for the entire corridor to open to public traffic.
4. Delhi-Amritsar-Katra Expressway
The Delhi-Amritsar-Katra Expressway is another major corridor being developed to improve connectivity between Delhi, Punjab and Jammu & Kashmir. The corridor is planned at approximately 687 km and is expected to provide faster connectivity towards important cities and pilgrimage destinations.
Current project listings have placed the target around December 2026, although package-wise construction and opening schedules can differ. The project is expected to improve connectivity for both passenger traffic and freight movement across northern India.
5. Amas-Darbhanga Expressway
Bihar is also seeing major highway development through the Amas-Darbhanga Expressway, also known as NH-119D. The greenfield corridor is approximately 189 km long and connects the Amas area in Gaya district with the Darbhanga region.
The project has been divided into multiple construction packages, with the revised completion target reported as December 2026. The corridor is expected to improve connectivity across Bihar and provide better access to important economic and cultural centres.
6. Chennai-Bengaluru Expressway
The Chennai-Bengaluru Expressway is being developed across Karnataka, Andhra Pradesh and Tamil Nadu. The corridor is intended to provide an alternative high-speed route between the Bengaluru and Chennai regions.
Some sections are already operational, while other packages remain under construction. Current 2026 project information indicates that several remaining sections have October milestones, although one Tamil Nadu package has faced delays that could push complete end-to-end opening beyond 2026.
Therefore, travellers should not assume that the entire Chennai-Bengaluru Expressway will become operational simultaneously.
7. Karaipettai-Walajapet Highway Project
Tamil Nadu is also seeing continued development on the Sriperumbudur-Walajapet section of the highway network. According to a Lok Sabha response from the Ministry of Road Transport and Highways, the Karaipettai-Walajapet stretch has a revised scheduled completion date of October 2026.
The project is important for improving road connectivity along one of Tamil Nadu’s major industrial and transportation corridors.
8. Kanpur Ring Road
The Kanpur Ring Road is another project with an October 2026 milestone. The first package is approximately 23.3 km and is being developed as a six-lane access-controlled greenfield corridor.
Project information indicates a target completion/opening for Package I in October 2026. The broader ring-road project is intended to divert through traffic away from central Kanpur and improve connectivity around the city.
9. Gujarat NH-48 Infrastructure Works
For Gujarat readers, National Highway 48 remains particularly important. Several bridge, flyover and vehicular-underpass works are being undertaken on important sections of NH-48. A March 2026 report based on a Central Government response said:
- Bharuch-Vadodara: seven bridges, flyovers and vehicular underpasses were targeted for completion by December 2026.
- Vapi-Surat and Surat-Bharuch: 16 bridges, flyovers and underpasses were under construction with completion targeted by January 2027.
- Rajkot-Jetpur NH-27: six-laning was targeted for January 2027.
For Surat and South Gujarat, these works could be particularly relevant because NH-48 is an important route for passenger and commercial traffic.
10. New Highway Projects and Bidding Activity
Not every important highway development in October–December 2026 will involve an opening. Some projects will move into tendering, bidding or construction stages.
For example, NHAI invited bids in September 2026 for services related to a four-lane greenfield expressway spur connecting the Delhi-Vadodara Greenfield Expressway near Bandikui with Jaipur. The bid deadline is November 2, 2026.
This highlights an important point: India’s highway expansion is happening through a combination of completed sections, construction packages, new approvals and fresh tenders.

What These Highway Projects Mean for India
The expansion of highways and expressways is not only about reducing travel time.
Faster Freight Movement
New access-controlled corridors can provide more predictable travel for trucks connecting industrial centres, warehouses, ports and markets.
Better Industrial Connectivity
Projects such as the Delhi-Mumbai Expressway and Raipur-Visakhapatnam corridor are designed to connect production centres with major markets and ports.
Reduced Pressure on Existing Highways
Ring roads and bypasses can divert long-distance traffic away from congested city roads.
Growth Around New Corridors
New interchanges and highway connections can influence logistics hubs, warehouses, industrial areas and surrounding urban development.
However, the actual economic and travel impact will depend on the completion of connecting roads, interchanges and other supporting infrastructure.
What to Expect From October to December 2026
The final three months of 2026 are expected to be important for India’s highway infrastructure.
October 2026 could see package-wise openings and completion milestones, particularly on sections of major expressways and regional highways.
November 2026 is expected to remain significant for the Delhi-Mumbai Expressway and other ongoing national corridor works, subject to construction progress and approvals.
December 2026 is particularly important for projects with year-end completion targets, including the Raipur-Visakhapatnam Economic Corridor and Amas-Darbhanga Expressway.
But completion targets should not be treated as guaranteed public opening dates. Highway projects can be affected by land acquisition, construction progress, safety inspections, approvals and package-level delays.
Conclusion
From October to December 2026, India is expected to see several major developments in highway and expressway infrastructure.
The Delhi-Mumbai Expressway, Raipur-Visakhapatnam Economic Corridor, Delhi-Amritsar-Katra Expressway, Amas-Darbhanga Expressway, Chennai-Bengaluru Expressway and major Gujarat NH-48 works are among the projects worth watching.
For travellers and businesses, the biggest impact will come gradually as individual sections become operational. For cities such as Surat, Vadodara, Delhi, Kanpur, Bengaluru, Chennai, Raipur and Visakhapatnam, improved highway connectivity could influence travel patterns and freight movement over the coming years.
