Dellingburn Street in Greenock will close for 20 weeks from Monday November 11 while Network Rail engineers carry out work to repair and strengthen the railway bridge over the B788.

The refurbishment of the bridge is part of a wider, rolling programme of maintenance work on structures which is designed to extend their lifespan and keep the network safe and reliable. It represents and investment of almost £1m to protect and prolong the life of the bridge.

Work on the bridge, near Morrisons in the town, includes improving the drainage and clearing adjacent vegetation, strengthening girders, repairing masonry, blast cleaning and repairing the metalwork, applying corrosion protection and painting.

To deliver this work safely and efficiently, the road needs to close to enable Network Rail to erect scaffolding and deliver work on the structure. Pedestrian and cycle access will be maintained throughout the road closure.

In addition to the disruption to the road network, there will be two weekends in January where the railway will be closed from close of service on Friday night until start of service on Monday morning to enable 54 hour continuous working. Buses will replace trains on the weekends of the 4th/5th and 11th/12th January.

Jeremy Spence, Network Rail programme manager, said: “We know that Dellingburn Street is a busy road and an important route for local traffic and we do not take the decision to request its closure lightly.

“We understand the impact that this potentially will have for both road users and those communities adjacent to the bridge works. However, this is the most efficient and safest way to undertake the work required on the bridge.

“Delivering this work in just 20 weeks is a logistical challenge but we have planned the job carefully with our contractors and will complete it with the minimum possible inconvenience to the local community.”

Network Rail has worked with Inverclyde Council to put in place an appropriate ‘all vehicle’ diversion and all local access has been retained either side of the bridge to industrial units and the near-by supermarket.
