Michael Davitt Bridge

📍 Achill Island, Mayo

🏛️ Attraction

Last updated: 22 May 2026

Overview

The Michael Davitt Bridge carries the R319 road across the Achill Sound, linking the Corraun Peninsula with Achill Island in County Mayo. More than a simple crossing, the structure has served as a vital lifeline for over 130 years. Today, its sweeping white arches and integrated LED lighting create a distinctive landmark against the Atlantic skyline. The bridge remains one of Ireland’s few manually operated swing bridges, offering a tangible connection to the island’s maritime past while accommodating modern traffic.

A Century of Engineering

Before the bridge opened, islanders relied on ferries or dangerous low-tide crossings. The first structure, authorised by the Board of Trade and named after the Irish land reform activist Michael Davitt, was completed in 1887. Built to handle horse-drawn carts, its steel bow-string girder design was an engineering feat for its time, costing £5,000 to construct.

Motorisation brought new challenges. By the 1930s, the original span had deteriorated and proved too narrow for cars. Mayo County Council commissioned a replacement that opened in 1949. At the time, it was the largest bridge project undertaken by an Irish firm, costing approximately £20,000. This second iteration served the community for six decades until its swing mechanism began to fail in the early 2000s.

The current bridge, unveiled in summer 2008, was designed by Malachy Walsh & Partners and constructed by SIAC Construction. While it pays homage to the original’s function, its aesthetic draws inspiration from the fluid, cable-tensioned style of Spanish architect Santiago Calatrava.

Design & The Swing Mechanism

The modern structure measures 225.5 m (740 ft) in length with a deck width of 6.5 m (21 ft 6 in). Weighing approximately 390 tonnes, it rests on a central pivot that allows the entire span to rotate. Unlike automated crossings elsewhere, the Michael Davitt Bridge is still operated manually. A single operator turns a hand-wheel to disengage the locking mechanism and swing the deck open for taller vessels.

Key specifications:

  • Length: 225.5 m (740 ft)
  • Width: 6.5 m (21.5 ft)
  • Weight: 390 tonnes
  • Operation: Manual hand-wheel swing
  • Lighting: Integrated LED arrays for night visibility

Because reopening the bridge requires significant physical effort, it is kept closed for routine traffic. Openings now occur primarily for scheduled sailing events, heritage days, or when specifically requested by larger craft. The 2017 Maritime and Heritage Festival marked the bridge’s 130th anniversary with a coordinated parade of yachts and traditional Achill yawls, giving visitors a rare live demonstration of the mechanism in action.

What to See & Do

Crossing the bridge is a straightforward drive, but the surrounding landscape rewards those who pause. The vantage point offers clear views of the Achill Sound channel, where local fishing boats and recreational yachts navigate the tidal waters. Photographers find the structure particularly striking during the blue hour, when the LED illumination contrasts with the darkening sky and the rugged silhouette of the nearby coastline.

The bridge serves as a natural gateway to exploring Achill Sound and the wider island. Drivers heading north can follow the coastal route toward Keem Bay and the Slievemore desert village, while those turning south will pass the historic ruins of Carrickkildavnet Castle. Cyclists frequently use the crossing as part of their route along the island’s coastal roads, enjoying the unobstructed sea views and steady gradient. For those seeking wilder terrain, a short drive inland leads to the boglands and mountain trails of Ballycroy National Park.

Visiting Tips

  • Timing the swing: Manual openings are uncommon. Check local sailing club schedules or Mayo County Council announcements during the summer months for planned heritage openings.
  • Photography: Arrive before sunset to capture the transition from daylight to the bridge’s LED activation. A tripod is recommended for long exposures of the illuminated arches.
  • Accessibility: The deck is fully level and suitable for standard vehicles and wheelchairs. Pedestrian footpaths run alongside the carriageway, though traffic stops briefly if the swing is operated.
  • Parking: Free short-stay parking is available in Achill Sound village. There are no designated bays directly on the bridge approach.

Practical Information

The Michael Davitt Bridge operates 24 hours a day with no admission charge. It is maintained by Mayo County Council and forms a critical part of the R319 route.

Getting there

  • By car: From Dublin, take the M6 to Castlebar, then the N5 to Westport. Follow the R319 north for approximately 20 km to reach Achill Sound. The journey takes around four hours from the capital.
  • By bus: Bus Éireann service 450 runs multiple times daily between Westport and Achill Island. Local Link service 460a connects Achill Sound with Castlebar.
  • By train: The nearest rail stations are in Castlebar and Westport, both accessible from Dublin Connolly via Irish Rail.

The bridge’s manual operation means it rarely interrupts daily traffic, though occasional delays can occur during scheduled maritime events. If you plan to photograph the crossing at night, arrive early to secure a safe viewing position on the village side, and keep a close eye on tidal conditions if you intend to walk the nearby foreshore. The structure stands as a working piece of civil engineering, still turning on its central pivot after more than a century of use.
