Napier Bridge, the arched crossing over the Cooum near its mouth that links Fort St George to the Marina, is not one bridge but three generations of them. The first was an iron lattice bridge put up by Lord Napier, Governor of Madras, in 1868-69. The arches you see today belong to a concrete bridge opened on 9 July 1944, which DT Next describes as the first prestressed concrete bridge in India. A matching western carriageway was added around 2000.
In the last few years the bridge has also become a backdrop: lit in blue at night, painted as a chessboard for the 2022 Chess Olympiad, and used as part of the Formula 4 night street circuit in 2024. Here is its history and how to see it.
Three bridges on one site
| Period | Bridge |
|---|---|
| 1868-69 | Iron lattice bridge on cast iron screw piles, built under Lord Napier |
| 1909 | Rebuilt with iron girders at a cost of Rs 3.75 lakh after sea air corroded the first |
| 1939-1944 | Concrete tied-arch bridge, opened 9 July 1944 |
| About 2000 | New western carriageway in a matching arched design |
Lord Napier, who governed Madras from 1866 to 1872, gave his name to the first bridge. Its iron did not cope well with the salt air at the river mouth, and by 1909 it had been replaced with iron girders, DT Next records.
The 1944 concrete bridge
In 1939 the city council considered replacing the girder bridge with a concrete one. The contract went to Gannon Dunkerley and Co., with the Madras Port Trust supervising. Work stopped for about a year during the wartime evacuation of Madras, when the city feared Japanese attack, and the contractor later charged an extra Rs 1.75 lakh. The Governor of Madras opened the new bridge on 9 July 1944.
DT Next gives these figures for the 1944 structure:
- Length: 489 feet
- Width: 56 feet
- Materials: about 240 tons of steel and 500 tonnes of cement
- Design: a tied-arch system with a string girder and vertical hangers
Structurae, the international bridge database, lists it as a tied-arch road bridge with prestressed concrete arches, built between 1939 and 1943. The separate western carriageway is listed as completed in 2000, with six bowstring spans across the river. The two decks together carry the heavy traffic of Kamarajar Salai between the fort and the beach.
Lights, chess squares and a race track
Night lighting. The Corporation of Chennai commissioned a lighting scheme as part of a wider plan for the city at night, designed by the Sydney firm Lighting Design Partnership with GA Architects, according to Thorn Lighting, which supplied the fittings. About 300 compact floodlights mounted low on the structure throw blue light under the arches, so the bridge seems to float over its reflection in the Cooum. Low lanterns replaced conventional streetlights on the deck.
Chessboard. Days before the 44th Chess Olympiad opened at Mamallapuram on 28 July 2022, the bridge’s surface and railings were painted in black and white squares. MyKhel reported that the event drew players from 187 countries. The look went viral, though it also drew crowds of people stopping for photos on a busy road.
Street circuit. The 3.5 km Chennai Formula Racing Circuit, launched in 2023, runs around Island Grounds, past the Victory War Memorial and across Napier Bridge, with 19 corners, DT Next reported. The state sports authority was to invest Rs 42 crore. Its first race weekend, on 31 August and 1 September 2024, was billed by evo India as the country’s first night street race.
How to see it
- Best time: just after sunset, when the lights come on and the arches show in the water.
- Where to stand: the footpaths on the bridge give close views. For the full arch profile, look from the Marina side near the Anna Square end or from the Fort side near the war memorial.
- Safety: do not stop vehicles on the deck for photos. Traffic is fast, and police have objected to sudden stops.
- Combine with: the Victory War Memorial, the Fort St George museum and the start of the Marina promenade, all within walking distance.
The Cooum under the bridge is still badly polluted, and the river mouth is often blocked by a sand bar, especially before the northeast monsoon. Expect a smell at low tide.
