UK - Weight restrictions were in place on the structure, resulting in limitations to the vehicles and cargoes crossing the bridge.

Collett has announced that while transporting the transformer to Harting Rig Wind Farm Substation, 3 miles from the site the Collett Team was challenged with crossing Glassford Bridge.

According to Collett, identified in the planning process, weight restrictions were in place on the structure, resulting in limitations to the vehicles and cargoes crossing the bridge. Their Team was also required to observe a maximum speed of 10mph and ensure that no other traffic or pedestrians would be present on the bridge during the transport operation.  In addition, all vehicles must stick to a 3m (1.9 miles) strip of the bridge, with a series of cat's eye markers in place to ensure each vehicle maintained a set alignment throughout.

According to the company, with the ability to control the trailer steering and braking, Collett's Steersman ensured that the trailer and cargo remained within the necessary alignment whilst traversing the structure.  Once clear of the bridge, and with the trailer brake applied, the secondary ballast unit took up the cable stack and crossed Glassford Bridge.
