New bus priority pilot launches on M4 motorway
A dynamic hard shoulder initiative has commenced for commuters travelling between Celbridge and Leixlip. This strategic transport project aims to enhance public transit efficiency by allowing buses to bypass congestion during peak periods on the eastbound route.
Kildare County Council, in collaboration with national transport bodies, has officially launched a pilot bus priority scheme on the M4 motorway. Stretching between Junction 6 at Celbridge and Junction 5 at Leixlip, the initiative permits buses to utilise the hard shoulder during periods of heavy traffic. This project serves as a key trial to assess the viability of similar sustainable transport measures across the national road network.
Operating dynamically, the system relies on overhead signage and CCTV monitoring to manage traffic flow. When specific congestion criteria are met, the hard shoulder is activated for bus transit, allowing vehicles to bypass delays. Once traffic levels normalise, the lane reverts to its standard use. Authorities have emphasised that this is not a permanent bus lane, and it remains strictly prohibited for use by taxis or private motorists at any time.
Drivers are urged to remain vigilant and follow all roadside signage to ensure safety during the trial period. The Council has reminded road users to adhere to speed limits, avoid mobile phone use, and keep the hard shoulder clear unless an emergency arises. Further information regarding the operational guidelines for this pilot programme is available on the official Kildare County Council website.
