Acrow installs temporary bridge for M28 Cork-to-Ringaskiddy project

Acrow Bridge has installed a modular steel detour route in County Cork, Ireland, to keep traffic moving during construction on the M28 Cork to Ringaskiddy Road Project. The temporary bridge on Maryborough Hill Road is meant to reduce disruption while a permanent bridge is replaced and the motorway corridor is widened.

Why it matters: - The temporary bridge helps keep traffic moving on Maryborough Hill Road, a key local route linking residential areas with the N28, the N40 South Ring Road and Cork city centre. - The detour reduces disruption while the M28 Cork to Ringaskiddy Road Project advances, with benefits for commuters, commercial traffic and local access. - The upgraded corridor is expected to improve road safety, cut congestion and create a faster, more reliable route to Ringaskiddy and its deep-water port.

What happened: - Acrow Bridge installed one of its modular steel bridges as a temporary detour route for the nationally significant M28 Cork to Ringaskiddy Road Project. - The bridge was placed on Maryborough Hill Road to maintain traffic while an existing bridge is replaced. - The project is funded by the Department of Transport through Transport Infrastructure Ireland. - The bridge was provided as a rental to project contractor BAM UK & Ireland.

The details: - Bridge components arrived at the site in early June 2026. - Site access was restricted because the bridge had to be positioned over an existing dual carriageway. - The bridge was built offline and moved into place on a Self-Propelled Modular Transporter during a road closure. - The bridge was then lifted into position using the largest mobile crane available in Ireland. - The bridge measures 42.51 metres long and 7.32 metres wide. - The structure includes two cantilevered pedestrian walkways. - The deck uses an epoxy-polyurethane-based anti-skid surface. - The bridge was designed to Eurocode LM1/LM4 loading.

Between the lines: - The temporary span shows how modular bridges can keep major transport projects moving without fully shutting down busy local roads. - Acrow’s local presence in Ireland may help the company compete for more short-notice and fast-deployment bridge work. - The opening of Acrow Bridge Ireland’s new facility in Birr, County Offaly, gives the company a base for faster delivery and support across the country.

What's next: - The temporary bridge will remain in place while the permanent bridge work continues as part of the broader motorway upgrade. - Acrow says its Irish facility will support rapid delivery for future temporary bridging projects. - The M28 project is expected to deliver longer-term transportation benefits for people and businesses in Ireland.

The bottom line: - The temporary modular bridge is a stopgap that keeps one of Cork’s key routes open while a major motorway upgrade is built.
