Merson Deliver Large-Scale Gantry Upgrades on the M8
As part of a major refurbishment programme, Merson-ASG were delighted be contracted to design, manufacture and install gantries on the M8 motorway. This project sees Merson-ASG provide a complete upgrade of 8 gantries on Scotland’s busiest road.

The M8 is one of the most important roads in Scotland, spanning approximately 60 miles in length, connecting Glasgow and Edinburgh, and with stretches of the road used by 180,000 vehicles per day it is one of Europe’s busiest motorways. As part of a large-scale upgrade, Transport Scotland announced a £6.5m investment to refurbish gantries along this road to bring them up to modern day standards. With many of the gantries on the M8 dating back over 30 years, this programme was designed to offer a complete overhaul which would include maintenance to the steelwork, an upgrade to the signage, and an improvement to energy savings through the use of innovative lighting solutions. 

Merson-ASG has previously worked in this capacity to deliver these unique gantries on the M74 in Scotland. Thanks to their considerable experience and expertise they are able to provide a fully integrated service across all aspects of this refurbishment to deliver the following:

• Removal of the gantry for the network.
• Removal and recycle of all existing finishes and electrics.
• Shot blasting to remove existing paint system.
• Application of a new paint system.
• Carryout of the repair to the steelwork as required.
• Manufacture and installation of new gantry cladding.
• Manufacture and installation of LED illuminated gantry sign fascia.
• Manufacture and installation of new gantry electrical equipment.
• Manufacture and installation of new GRP gantry floor.
• Lease with traffic Scotland with regards to refurbishment of ITS equipment.
• Installation of the gantry back on to the road network.

Site installation is carried out overnight and involves coordinating the closure of either the East of West bound route in attempt to minimise disruption to the road users. A dedication to health and safety standards is at the forefront and both internal teams and subcontractors are well equipped with procedures to ensure the safety of themselves and anyone using the roads.

The refurbishment of these structures provides a great example of modern day gantry design and installation. Because the unique structures are refurbished, material waste is kept to a minimum and with the use of new LED lighting, there is a significant saving on power.
