Heavy Rain Submerges NH-66 Stretch in Raigad; Landslide Hits Roha

RAIGAD, India — Torrential monsoon downpours across coastal Maharashtra have severely disrupted transit infrastructure, submerging a critical stretch of National Highway 66 (NH-66) and triggering a landslide on the Roha-Alibag road. Local disaster management officials issued an urgent travel advisory on Tuesday, July 7, 2026, urging motorists to avoid affected local highways and instead utilize the Mumbai-Pune Expressway for regional travel.

The severe weather has caused widespread flooding in low-lying pockets of the Raigad district, stranding thousands of travelers and halting multi-state supply lines. Emergency state personnel and regional police divisions have deployed monitoring units along major choke points to divert incoming traffic away from flooded river catchments.

NH-66 Flooding and Localized Landslide Disruptions

According to logs provided by the Raigad District Collectorate, the worst-affected zone on the Mumbai-Goa Highway (NH-66) is the Sukeli Ghat section near Nagothane. Inundation from overflowing streams caused floodwaters to rise nearly three feet across the asphalt, rendering the stretch entirely impassable for small consumer vehicles and heavy transport trucks alike.

The resulting gridlock produced vehicular queues extending eight to ten kilometers on both sides of the highway. Simultaneously, a localized landslide near the Roha-Alibag arterial link brought down heavy boulders and mud onto the roadway, completely cutting off direct access between the regional industrial belts and the coastal district headquarters.

State Public Works Department (PWD) teams equipped with earthmovers have arrived at the Roha-Alibag site to clear debris, but persistent rains continue to hamper mechanical recovery operations.

Regional Travel Diversions and Economic Impact

The India Meteorological Department (IMD) has maintained a high-level weather alert for Raigad and adjoining Konkan districts, forecasting sustained heavy-to-very-heavy rainfall over the next 48 hours. In response to the double bottleneck on NH-66 and the Roha link, traffic police are actively rerouting commuters.

Motorists attempting to travel between Pune, central Maharashtra, and the coastal towns are being redirected via Mangaon and Nizampur through the Tamhini Ghat. For travelers moving between Mumbai and Goa, state highway authorities strongly recommend taking the automated toll routes on the Mumbai-Pune Expressway or utilizing scheduled Konkan Railway services, which continue to operate under cautious monsoon speed restrictions.

The transportation halts are directly impacting supply chains, delaying the movement of perishable agricultural goods and industrial raw materials bound for Jawaharlal Nehru Port Trust (JNPT) and manufacturing zones in Roha.

Official Statements

"Heavy waterlogging inside Sukeli village limits forced an immediate suspension of traffic to ensure public safety," noted a district transport official in an advisory broadcast on Tuesday morning.

The Maharashtra State Road Development Corporation (MSRDC) added that structural monitoring remains active across all major ghats, with quick-response engineering cells positioned at vulnerable slopes to address sudden terrain shifts.

Why It Matters

The flooding of NH-66 and the blockage of the Roha-Alibag road cut off vital lifelines for local residents, daily commuters, and tourist transit systems. Adhering to the expressway diversions prevents hazardous strandings in landslide-prone ghats, minimizes emergency rescue strains, and keeps industrial cargo flowing through verified, higher-altitude alternative networks.

Key Facts at a Glance

• NH-66 Status: Closed near Nagothane due to three-foot-deep waterlogging blocks.

• Landslide Impact: Roha-Alibag road cut off completely by boulder collapses.

• Recommended Detour: All long-distance motorists are advised to use the Mumbai-Pune Expressway.

• Weather Warning: IMD has issued an active red alert for the Raigad district.

Frequently Asked Questions

Is the entire Mumbai-Goa Highway (NH-66) closed to traffic?

No, but critical low-lying segments—specifically the Nagothane-Wakan stretch and Sukeli Ghat—are heavily submerged or restricted, causing severe ripple delays across the entire highway network.

How long will it take to reopen the Roha-Alibag road?

Local PWD authorities indicate that debris clearing is underway, but full restoration depends on a temporary slowdown of the active rainfall to prevent secondary mudslides.

Are alternative mountain passes like Tamhini Ghat safe to use?

While open for diverted traffic, authorities advise extreme caution when traversing Tamhini Ghat due to reduced visibility from dense fog and the ongoing threat of small rockfalls.
