Overview
The Michael Davitt Bridge is a striking swing bridge that carries the R319 road across the Achill Sound, joining the rugged Corraun Peninsula with Achill Island in County Mayo. Its sleek, white arches are illuminated by LED lighting after dark, turning the structure into a beacon that can be seen from the surrounding hills. As you drive over, the bridge’s central pivot opens to let sailing vessels and fishing boats pass, offering a rare chance to watch a piece of moving engineering in action.
History
The story of the bridge begins in the early 1880s, when islanders were forced to rely on ferries or risky low‑tide crossings on foot or horseback. A Mayo County surveyor, Mr Glover, drafted plans that were approved by civil engineer J Price and authorised by the Board of Trade in London. The original bridge, named after the famed Irish activist Michael Davitt, opened in 1887 and was built to carry horse‑drawn traffic. Its steel bow‑string girder spanned the channel on a central pier, with a roadway just wide enough for the era’s traffic.
By the 1930s the structure had deteriorated, and the rise of motor vehicles made the narrow bridge unsafe. In 1947 Mayo County Council commissioned a replacement, and the new bridge was completed in early 1949 – at the time the largest bridge project undertaken by an Irish company. This second bridge served the island for six decades, but by the early 2000s its swing mechanism was failing.
A third incarnation was unveiled in summer 2008. Designed by Malachy Walsh & Partners and built by SIAC Construction, the new bridge draws inspiration from the work of Spanish architect Santiago Calatrava. Although modern in appearance, it retains the manual swing operation that has defined the crossing for more than a century.
Engineering and Design
The 2008 bridge is a 225.5 m (740 ft) span with a deck width of 6.5 m (21 ft 6 in). It weighs approximately 390 tonnes. Its white, cable‑tensioned arches echo Calatrava’s signature style, while integrated LED lighting highlights the structure at night, creating a striking silhouette against the Atlantic sky.
Construction cost figures are recorded for the earlier phases: the original 1887 bridge cost £5,000, and the 1949 replacement cost about £20,000. The 2008 project was funded by Mayo County Council and the Irish Government, though the exact figure is not published.
The swing mechanism remains manually operated by a single operator using a hand‑wheel. While the bridge can still open for vessels, it is now opened only on special occasions or when required for taller craft, as the effort to close it after opening is considerable.
What to See & Do
Crossing the Michael Davitt Bridge is an experience in itself. When the bridge swings open, you can watch local yachts, fishing boats and occasional pleasure craft glide through the channel. The surrounding landscape – rugged cliffs, sweeping dunes and the deep blue of the Atlantic – makes for excellent photography, especially at sunrise or when the bridge is lit at night.

The bridge also serves as a convenient launch point for exploring Achill Island’s attractions. From the bridge you can head north to the dramatic cliffs of Keem Bay, or south towards the historic ruins of Carrickkildavnet Castle. Cyclists and walkers often use the bridge as part of the Great Western Greenway, a scenic route that threads through the island’s coastal villages.
Events and Festivals
The bridge celebrated its 130th anniversary in 2017 with a Maritime and Heritage Festival. As part of the programme the swing was operated at 5 pm to allow a parade of yachts and traditional Achill yawls to pass, giving visitors a rare live demonstration of the bridge in action. Similar openings have been arranged for local sailing events and occasional heritage days.
Because the manual swing is labour‑intensive, the bridge is normally kept closed. Visitors hoping to see it open should check the Mayo County Council website or local notices during the summer months, when sailing activity peaks and special openings are more likely.
Visiting Tips
- Best time to watch the swing – late spring to early autumn, especially on weekends when sailing clubs schedule passages.
- Photography – the bridge is spectacular at sunrise, during the blue hour, and when the LED lights are on after dusk. A tripod helps capture the long exposure of the illuminated arches.
- Accessibility – the deck is level and suitable for cars and standard wheelchairs, but there is no dedicated ramp for the swing mechanism. Pedestrians can cross when the bridge is closed; the swing may cause brief delays.
- Parking – free short‑stay car parks are available in Achill Sound village. There is no dedicated bridge parking.
- Nearby attractions – combine a visit with the ruins of Carrickkildavnet Castle, the sandy beach at Keem Bay, the deserted village at Slievemore, and a drive into Ballycroy National Park for wild Atlantic scenery.
Practical Information
The Michael Davitt Bridge forms part of the R319, the main road onto Achill Island. It is open 24 hours a day and there is no admission fee – the crossing is free for all road users. The bridge is maintained by Mayo County Council.
Getting there
- By car: From Dublin, follow the M6 to Castlebar, then the N5 to Westport and the R319 to Achill Sound. The drive takes about four hours. Detailed routes are available at the AA routes site.
- By public transport: Bus Éireann service 450 runs from Westport to Achill several times daily; Local Link operates service 460a from Achill Sound to Castlebar. For rail travellers, the nearest stations are Castlebar and Westport, with connections from Dublin via Irish Rail.
- By air: Ireland West Airport Knock is a 75‑minute drive from the bridge, offering flights to several UK cities.
Parking is available in the nearby village of Achill Sound, where several car parks are free for short stays. The bridge itself has no dedicated parking; visitors are encouraged to use the village facilities.
Accessibility: The bridge deck is level and suitable for standard vehicles, but there is no dedicated wheelchair ramp on the swing mechanism. Pedestrians can cross when the bridge is closed; however, the swing operation may temporarily halt foot traffic.
Nearby accommodation: Options range from the seaside Seapoint House to the cosy Glenderan B&B, all within a short drive of the bridge.
Seasonal notes: The bridge’s swing mechanism is most frequently used during the summer months when sailing activity peaks. In 2010 a temporary failure caused a two‑hour traffic delay, but the issue was resolved and the bridge has operated smoothly since early 2011.
