Construction of Mersey Gateway Bridge - rodrigo - 2021-04-15
Dear Friends, first sequence of this time lapse I shot back in April 2017, using the Canon 5D MK IV, with tokina16-28 @ 228mm, f11, ISO 100; for the closed up sequence I used the Tamron 160-600 @ 150, f11, ISO100.

The Mersey Gateway Bridge is a toll bridge between Runcorn and Widnes in Cheshire, England which spans the River Mersey and the Manchester Ship Canal. The crossing, which opened in October 2017, has three traffic lanes in each direction and is approximately 1.5 km (1 mile) east (upstream) of the older Silver Jubilee Bridge. It forms part of a wider project to upgrade the infrastructure around the Mersey crossings that includes major civil engineering work to realign the road network, change and add tolling to the Silver Jubilee Bridge, and build new interchanges together with landscaping 9 km (6 miles) of highway.
The bridge has three towers that support a cable-stayed crossing over the river, while the southern approach creates a second bridge over the Ship Canal. The three towers are different heights: an 80 m (260 ft) central pylon, a 110 m (360 ft) pylon on the north side and a 125 m (410 ft) south pylon.
The total cable stayed span is 998 metres (3,274 ft), made up of two main spans of 318 metres (1,043 ft) and 294 metres (965 ft), and two side spans of 205 metres (673 ft) and 181 metres (594 ft). The crossing's total length, including approach viaducts, is 2.3 km (1.4 miles). The deck is made from reinforced concrete with a maximum clearance of 23 m (75 ft) above the river. As the water depth was too low at this point for marine construction vessels, a 1.5 km (1-mile) trestle was built out into the Mersey to drive in the bridge's pilings.
Enjoy,
