Mersey Gateway Bridge project progress

Work is well in hand on the Mersey Gateway Bridge project in the UK. The bridge construction work has now reached a major milestone. The south pylon of the Mersey Gateway has been completed, marking the project’s highest point in the River Mersey estuary. The south pylon stands 125m high, with the north pylon due to be completed in the next few days. The smaller central pylon, which is due to be finished in November, will be 80m high.

The Mersey Gateway Bridge project in the UK has reached a major milestone in its construction
Work is well in hand on the 6126 Mersey Gateway Bridge project in the UK. The bridge construction work has now reached a major milestone. The south pylon of the Mersey Gateway has been completed, marking the project’s highest point in the River Mersey estuary. The south pylon stands 125m high, with the north pylon due to be completed in the next few days. The smaller central pylon, which is due to be finished in November, will be 80m high.

A specialist automatic climbing system is being used to construct the bridge pylons. This equipment builds one vertical 5m section at a time. It then repeatedly climbs upwards to create the next section until the structure is complete. Construction teams have completed 30 sections for the south pylon and 27 for the north pylon. In all, 21 sections will be built for the central pylon. A total of 2,230m3 of concrete was poured for the south pylon, and 1,890m3 for the north pylon.

Gareth Stuart, project director at Merseylink, said, “Hitting the highest point on the project is a significant milestone and it’s a testament to the tenacity and expertise of our construction crews who have worked extremely hard, often in challenging conditions, to get the job done. We’ll be holding a special site celebration to thank all of the teams involved.”

The next phase of work involves installing steel stay cables to connect the three bridge pylons to the main bridge deck. This will begin in the next couple of weeks. Halton’s six-lane river crossing is on schedule to open in autumn 2017.

    Three years ago a welder’s cut halved Canada’s old Port Mann Bridge. David Arminas reports from the banks of the Fraser River. By the time this issue of World Highways reaches you, one of Canada’s iconic steel arch bridges will be a shadow of its former self. It’s been a three-year demolition job since the first cut across the deck of the old Port Mann Bridge just outside the city of Vancouver on Canada’s Pacific coast. A new 10-lane 2.2km Port Mann Bridge opened in 2012 (see box). It runs parallel to the o

    Taking a road and rail link across one of the biggest rivers in South America, together with its swamps and flood-plain, called for a new crossing of truly superlative dimensions. Two 135.5m pylons for the third bridge across the Orinoco River, at Caicara del Orinoco, in Venezuela took shape with a formwork solution and automatic climbing technology from Doka. The bridge has an overall length of just over 11km and the main bridge is nearly 2.3km long with the roadway 55m above the river. The two ident
