Sahar Elevated Access Road The Sahar Elevated Access Road is an elevated highway serving Chhatrapati Shivaji Maharaj International Airport in Mumbai, Maharashtra. The project connects the airport complex to arterial roads near Andheri and Worli and was delivered by a consortium including Tata Projects, Larsen & Toubro, and agencies such as the Mumbai Metropolitan Region Development Authority and the Mumbai International Airport Limited. The facility reduced journey times between the airport and central Mumbai, integrating with regional infrastructure nodes like the Western Express Highway and the Mumbai Suburban Railway.

Overview

The corridor provides a grade-separated link between the airport precinct adjacent to Terminal 2, Mumbai and surface roads near Andheri East, traversing over Sahar Road and interfacing with the Mumbai Trans Harbour Link corridor planning zones. It was conceived to mitigate congestion on the Western Express Highway, the Eastern Freeway approaches, and feeder streets serving the Mumbai Metropolitan Region. Stakeholders included the Bombay High Court in adjudications, municipal authorities such as the Brihanmumbai Municipal Corporation, and transport planners from the Jawaharlal Nehru Port Trust-adjacent study groups.

History and Planning

Initial proposals emerged amid capacity debates at Chhatrapati Shivaji International Airport during the early 2000s, concurrent with expansion works overseen by International Finance Corporation advisors and concessions granted under models familiar to Private Finance Initiative projects. The scheme followed feasibility studies by consultants with prior work for Delhi Metro Rail Corporation and input from traffic modellers experienced with National Highway Authority of India projects. Land acquisition and clearances required coordination with the Directorate General of Civil Aviation, the Ministry of Civil Aviation, and local planning tribunals, while financing structures mirrored arrangements used in Mumbai Metro concessional contracts.

Design and Construction

Engineering designs incorporated pre-stressed concrete viaducts and segmental box girders, reflecting techniques used by Larsen & Toubro on projects like the Mumbai-Pune Expressway. Structural design reviews referenced codes from the Bureau of Indian Standards and seismic guidelines aligned with assessments by institutions such as the Indian Institute of Technology Bombay. Construction management involved staged traffic diversions coordinated with the Mumbai Police traffic unit and utility relocations negotiated with BSES and Brihanmumbai Electric Supply and Transport. Contractors employed incremental launching methods similar to those used on Bandra-Worli Sea Link, and project monitoring used surveying standards from the Survey of India.

Route and Features

The elevated roadway spans approximately 2.2 kilometres, beginning within the airport compound near Terminal 1/Terminal 2, Mumbai precincts and terminating at a grade-separated junction close to Andheri East urban corridors. It incorporates features such as dedicated entry/exit ramps, tolling booths in line with National Highways Authority of India practices, drainage systems coordinated with the Central Water and Power Research Station guidelines, and lighting conforming to specifications observed in projects by the Indian Roads Congress. The alignment crosses urban fabric near landmarks like Sahar Village and provides visual sightlines towards Juhu Beach and the Mumbai skyline.

Operations and Maintenance

Operational control is vested in agencies including the Mumbai Metropolitan Region Development Authority and concessionaires who apply maintenance regimes similar to those used by Mumbai Port Trust for elevated structures. Routine inspections reference manuals from the Ministry of Road Transport and Highways, while pavement upkeep and resurfacing contracts follow procurement precedents established by the Asian Development Bank-funded programs in the region. Traffic enforcement and emergency response are coordinated with the Mumbai Traffic Police and airport authorities such as Air India ground operations and the Airport Authority of India liaison units.

Impact and Controversies

The project produced measurable travel-time savings cited in transport studies by academic units like Indian Institute of Technology Bombay and policy groups associated with NITI Aayog, but it also provoked controversies over land acquisition adjacent to Sahar Village, environmental impact assessments involving the Mithi River catchment, and evictions contested in forums including the Bombay High Court. Critics compared the scheme's cost-benefit profile to other urban infrastructure initiatives such as the Mumbai Metro phases, while proponents highlighted synergies with the Delhi-Mumbai Industrial Corridor narratives and benefits for aviation stakeholders like Mumbai International Airport Limited and carriers operating from Terminal 2, Mumbai.
