It has been roughly 4 months since our last update of the Mersey Gateway project  and since then quite a lot has happened. For the first time visible structures are emerging from the River Mersey and other important structures are starting to be constructed.  In September a major milestone was reached when Europe’s longest bridge-building machine was named after a 3 month assembly process. The machine known as a movable scaffolding system (MSS) has been named Trinity. Trinity will be used to construct the main elevated approach roads leading to the bridge. The machine will act as an enormous mould into which concrete is poured, after each 70 meter section of concrete has set Trinity will then move on to the next section.  Despite weighing 1700 tonnes and being 75m long Trinity will move from pier to pier in one piece. The machine will do this using 2 175m long rails onto which she sits. There is a video of how the movable scaffolding system works  here . Trinity will
