Requirement

Transport for Greater Manchester is extending its Metrolink tramline to connect the city centre with the Trafford Centre shopping and leisure complex. The extension to the existing Eccles Line will branch off at the elevated Pomona station, where a viaduct was needed to take the tramlines down to wharfside level.

Total tonnage of steel work

Full length of the structure

-1

Completed ahead of schedule

Solution

The bridge design comprised 17 girders, delivered as a header beam and eight braced pairs. These spanned between a new abutment, the header beam and were supported by three intermediate concrete piers.

Challenges

The principle challenge for this project was installing the 38-metre girder pairs on the very congested site, a narrow strip with canals to the North and South, an adjacent network rail line, A5063 to the West and the live Metrolink Eccles line to the East.

Outcomes

The client was impressed with the performance of Cleveland Bridge throughout the project, particularly its management of logistics and installation on such a restricted site. The whole project was completed a week ahead of Schedule.

Cleveland Bridge brought valuable specialist expertise to the project. Their ability to deliver and erect this complex strategic heavy structure on such a narrow strip of land was very impressive. The steel components fitted precisely and the whole installation was completed ahead of time, ensuring the tramline extension programme remained on schedule.
