Navi Mumbai Coastal Road Status & Latest Update
Work on the Navi Mumbai Coastal Road has progressed with seawall reinforcement and bridge pile construction. The engineering team is focused on completing creek spans near Ulwe to allow smooth corridor connections.
Environmental compliance tracking remains active to safeguard local mangroves. Joint planning is underway with the airport authority to establish seamless entry and exit interfaces with the terminal bypass routes, aligning with the environmental standards set by the Mumbai Coastal Road project.
Navi Mumbai Coastal Road Route Map & Alignment
The alignment starts on the northern side from Amra Marg near Belapur, runs along the coastline of Ulwe, and links directly with the main transit loops servicing the Jawaharlal Nehru Port and the upcoming airport.
The Navi Mumbai Coastal Road, officially developed by CIDCO, is a proposed 9.6 km coastal highway corridor designed to connect Amra Marg in Belapur to Ulwe and the JNPT area, bypassing congested internal Navi Mumbai nodes.
The route map starts at Amra Marg (Belapur), runs southwards along the Ulwe coastline, intersects with the Atal Setu (MTHL) interchange, and extends down to the JNPT port area and Navi Mumbai International Airport corridor.
The coastal road features specialized exit ramps and bypass corridors that connect directly to the Navi Mumbai International Airport's core terminals, providing a traffic-free access route for passenger vehicles.
It features a direct interchange near the Ulwe coast. Commuters coming from South Mumbai over the Atal Setu (MTHL) can exit onto the Navi Mumbai Coastal Road to head north towards Belapur or south towards the airport and JNPT.
The estimated cost of the Navi Mumbai Coastal Road project is approximately ₹700 Crore. As a major CIDCO infrastructure initiative, the funding covers land reclamation, coastal protective bunds, and civil construction for the 6-lane highway segments.
As of 2026, the Navi Mumbai Coastal Road is under active construction. Contracts for civil packages have been awarded, and earthworks, coastal protective bunds, and piling operations are currently progressing along the coastal alignment.
The project is targeted for completion around 2027–2028 (projected), aligning with the commercial commissioning schedule of the Navi Mumbai International Airport.
The term CIDCO Coastal Road most commonly refers to the Ulwe Coastal Road, a six-lane road being developed by the City and Industrial Development Corporation (CIDCO) in Navi Mumbai. It is designed to connect Amra Marg with the Mumbai Trans Harbour Link (Atal Setu) junction at Shivajinagar, Ulwe, while also providing a direct airport link toward Navi Mumbai International Airport.
The main Ulwe Coastal Road route runs from Amra Marg through the Ulwe area to the Mumbai Trans Harbour Link junction at Shivajinagar. A separate airport link connects the corridor toward Navi Mumbai International Airport, improving access between Atal Setu, Ulwe and the airport.
The main CIDCO Ulwe Coastal Road starts at Amra Marg and terminates at the MTHL/Atal Setu junction at Shivajinagar in Ulwe. The associated airport link continues toward the Navi Mumbai International Airport site.
The CIDCO Coastal Road alignment follows the Ulwe corridor between Amra Marg and the Atal Setu junction. The project passes through environmentally sensitive coastal and mangrove areas, requiring major sections to be constructed on stilts. The airport link forms a separate connection from the main road toward Navi Mumbai International Airport.
The main Ulwe Coastal Road is approximately 5.8 km long. CIDCO's environmental documentation also identifies an approximately 1.2 km airport link, while later project descriptions specify about 0.903 km for the airport link. Therefore, the commonly quoted main-road length is 5.8 km, while the broader road-and-airport connectivity corridor is roughly 6.7 km depending on the scope used.
The current CIDCO project cost for the Ulwe Coastal Road is about ₹1,591.32 crore excluding GST. The project was originally estimated at around ₹700 crore, but the cost increased substantially after the alignment and structural design were modified to address CRZ and mangrove-related requirements.
The project cost increased largely because sections originally planned using conventional construction methods had to be redesigned with stilt or elevated structures to comply with environmental and coastal-zone requirements. Additional coordination and infrastructure requirements also contributed to the higher project cost.
Yes. The Ulwe Coastal Road is under construction. CIDCO began construction in 2024, and work has progressed across the main road, elevated structures and airport connectivity sections. The project is being executed in phases because of the modified design and environmental requirements.
The Ulwe Coastal Road remains under construction, with substantial structural work completed but the full corridor not yet commissioned for traffic. Current project reporting has placed completion around September 2026, followed by an expected opening window around October or November 2026. These dates should be treated as targets until CIDCO formally announces commissioning.
The latest developments concern continued construction of the Ulwe Coastal Road and its Atal Setu connection. In 2026, CIDCO also advanced work related to the MTHL interchange and further planning for a possible extension of the Ulwe Coastal Road toward Dronagiri and the Karanja-Rewas Bridge. The main 5.8 km road itself remains under implementation.
The road is designed to provide a more direct connection between the Mumbai Trans Harbour Link at Shivajinagar and Navi Mumbai International Airport. The main Ulwe Coastal Road connects Amra Marg with the Atal Setu junction, while a separate airport link provides access toward the airport site.
Significant portions of the Ulwe Coastal Road pass through coastal regulation and mangrove-sensitive areas. The design was therefore modified to use stilt or elevated construction in sensitive sections, helping maintain tidal-water movement and reduce the impact on mangrove ecosystems.
A separate extension of the Ulwe Coastal Road is being planned beyond the MTHL junction toward the Dronagiri Coastal Road and the proposed Karanja-Rewas Bridge. CIDCO invited proposals for preparation of a detailed project report for this extension in 2026. It is a separate proposed extension and should not be included in the current 5.8 km project length.
No. Both are CIDCO coastal-road projects in Navi Mumbai, but they are separate projects with different alignments and scopes. The Ulwe Coastal Road connects Amra Marg with the Atal Setu junction and airport corridor, while the Kharghar Coastal Road is a separate corridor intended to improve connectivity around Kharghar, CBD Belapur and the Navi Mumbai airport region.
The main purpose of the Ulwe Coastal Road is to improve road connectivity between Navi Mumbai International Airport, Ulwe, Amra Marg and the Mumbai Trans Harbour Link. It is intended to provide a more direct airport approach, improve regional connectivity and reduce dependence on existing congested routes.
