Eastern Metropolitan Bypass

Eastern Metropolitan Bypass (also known as E.M. Bypass or EM Bypass) is a 32 km long six to eight-lane major bypass road on the east side of Kolkata in the Indian state of West Bengal. It connects Ultadanga (North Kolkata) to Baruipur Puratan Bazar (under Kolkata metropolitan area). The road is a major link to Salt Lake and New Town. EM Bypass is part of State Highway 3. EM Bypass is centered with major hotels, business parks, high residential blocks and other high-end construction and development.

History and development
The Eastern Metropolitan Bypass was constructed during the 1980s and became operational in 1982. The construction disrupted part of the East Kolkata Wetlands.

It was designed as a six to eight-lane bypass to lessen traffic congestion on the entire stretch of Gariahat Road. Several consequent connections have been made to Gariahat Road to further move traffic to the Bypass.

At one point in 2010 the road was officially named Jyoti Basu Sarani after Jyoti Basu. The road was further renamed Biswa Bangla Sarani by the Chief Minister Mamata Banerjee in 2011.

The road is undergoing expansion under the JNNURM.
