Airoli Katai Tunnel Road

The Airoli-Katai tunnel road is a breath of fresh air for people living around Kalyan-Shil and Navi Mumbai. The 3-phase road project is finally taking shape. In fact, a few phases of the project are nearing completion.

What Is Airoli Katai Tunnel Road?

The Mumbai Metropolitan Region Development Authority (MMRDA) has finalised the plan to construct Airoli-Katai Tunnel Road. It is a 1.7km long road connecting Airoli to the Kalyan-Shil corridor via a tunnel cutting through Parsik Hill. The 1.7km Tunnel Road is a part of the 33.8km long road, starting from Airoli to Katai Naka on the Kalyan-Shilphata road. It traverses through mangroves, valleys, flyovers, and railway lines. The six-lane road will significantly cut down the travelling time between Airoli to Shilphata.

Today if you want to reach Shilphata from Airoli or Mumbai, you will need to go all the way around Parsik hill and travel via high traffic areas of Mahape or Mumbra. The travel time can be over an hour during peak traffic hours. The Airoli-Katai tunnel road cuts straight through Parsik hill in a straight line from Airoli allowing you to bypass Mahape and get to Kalyan-Shil road in about 20 minutes.

The complete project is to be developed in 3 phases. The cost of the whole project is estimated to be approximately 950 crores. 

Phase 1 – An elevated road connecting Thane-Belapur road to NH-4 shall be completed by March 2022. The 1.7-km tunnel road cutting through Parsik hill will be completed by March 2023. 

Phase 2 – Elevated road between Mulund-Airoli creek bridge and Thane-Belapur road is likely to be completed by December 2022. 

Phase 3 – This phase is in the tendering stage. It is an elevated road between NH-4 and Katai Naka.


As of January 2023, the elevated road between Airoli and Katai Naka is 88% complete. The twin tunnels are 66% complete.

How Will Airoli-Katai Tunnel Road Help Residents Of the Adjoining Areas?

The Airoli-Katai Tunnel road will transform the lives of people living in Dombivli East, Kalyan-Shil Road, and Navi Mumbai. Residents of premium township projects like Marathon Nextown are the biggest beneficiaries of this project. 

For thousands or lakhs of commuters who commute daily via this route, the travelling time gets reduced by 30-40%. The tunnel road also provides them with easy and faster access to industrial hubs of Badlapur and Bhiwandi. It also offers direct road connectivity to Mulund and other central suburbs of Mumbai. Did you ever imagine driving from Dombivli or Kalyan to the western suburbs of Mumbai, like Borivali and Andheri, in just an hour? Thanks to the Airoli-Katai Tunnel road, this 45-km long journey will now be quick and smooth.

How Will Airoli-Katai Tunnel Road Shape the Real Estate Market?

The Tunnel Road effortlessly delivers two important things – infrastructure boost and smooth connectivity. Both these things can be the growth catalyst and will enhance the real estate pricing of Kalyan-Shil Road, Dombivli, and Navi Mumbai.

Even today, there is a huge demand for residential properties in the surrounding areas around Airoli-Katai tunnel road. This demand will further escalate once this road is operational. It will pave way for the emergence of other facilities like shopping malls, colleges, commercial spaces, and much more. The development in this area is set to replicate the rapid development of Ghodbunder Road in Thane.

The futuristic location caters to all your housing needs. Whether you’re a first-time homebuyer looking to buy affordable homes or luxurious homes in premium townships, this location has it all!
