Meghna Bridge, Road bridge in Dhaka, Bangladesh

Meghna Bridge is a road bridge that crosses the Meghna River with a dual carriageway and pedestrian walkways on both sides. It connects major highways and carries traffic between important economic centers in the region.

Built with financial help from the Government of Japan and constructed by Nippon Koei Co. Ltd., the bridge opened on 1 February 1991. It is the single largest project with Japanese assistance in the world. In 2005 and again in 2012–13, damaged expansion joints required extensive repairs, and the piers were protected against scour at the riverbed.

The bridge's formal name, Japan Bangladesh Friendship Bridge 1, is rarely used locally; people call it Meghna Bridge after the river it crosses. A 2004 survey by the Embassy of Japan in Bangladesh found residents credited the crossing with reducing weather-related traffic blockages and with urbanising the surrounding area.

The bridge carries the Dhaka–Chittagong Highway, about 30 km southeast of Dhaka, with a 0.80 m sidewalk on each side for pedestrians. The carriageway is 7.2 m wide, so walkers share a narrow edge with traffic. The deck runs roughly northwest to southeast across the Meghna River.

The bridge's 13 spans are not uniform: nine measure 87 metres, one 48.3 metres, two 24.25 metres and one 18.2 metres. Its piers are hexagonal RCC solids, each 11 metres long and 3.2 metres wide, founded on buried caissons and piles. The 930-metre deck carries a 7.2-metre carriageway with 0.80-metre footpaths on both sides.
