Current Long Span Bridges This final lecture outlines some of the various LSBs currently under construction around the world (Spring 2017). Presentation at university of Surrey April 2017 by David Collings BSc CEng FICE Making the complex simple
Sungai Brunei Bridge I had previously prepared a design for a bridge on this site, and it was good to see this 300m span bridge underway in 2015. In 2016 the pylon was complete. In 2017 the bridge is complete with it¡¯s gold dome.

Sungai Brunei BridgeTemburong Bridge ? Whilst in Brunei, another major bridge under construction is the Temburong Bridge over Brunei Bay . Like the recently completed Penang crossing this is mainly 55m viaduct (18km) with a modest span CSB for ships.
Subiya Causeway Another sea crossing , this 35km across the bay at Kuwait. I designed the lifting frames and some temporary works for the viaducts. The longer span over the shipping channel is an odd looking one sided CSB.
In the lectures we have been looking to balance the stays a the towers. Here that has not occurred, the stays on one si missing, leading to an unbalanced design with large tie-dow
Izmit Bay Bridge This 1550m span is bridge complete. I am looking forward to the start of the next big bridge in Turkey with a world record span of 2030m.
Halogaland Suspension Bridge ? This 1145m span bridge is interesting in it will bring the cables together over the tower, improving torsional response but maybe making deck construction more difficult. The towers are complete and spinning of cables started but delayed due to problems with the temporary catwalk (remember Izmit 2016?)

Izmit Bay Bridge 2016
HZM Bridges The bridges and viaducts on this project are largely complete, with finishing's to be completed. The last tunnel section was recently completed, leaving fitting out of the tunnel M&E works before opening of the link.

3rd Bosporus Bridge This 1408m span is a hybrid with cable stays and suspension cables. Often combined in early bridges this hybrid stay-suspension form gives a stiffer structure and is likely to be more common in future suspension bridges. The
Queensferry Bridge This bridge the 3rd bridge across the Fourth of Firth. It has a couple of spans of 650m, and is the first of a series of 3 tower bridges. The deck and stay installation are now complete.
Mersey Gateway Another 3 tower bridge, this 1000m crossing of the Mersey uses a different method of stiffening, supplementing the stiff box-girder deck with a low central tower.
Tapan Zee An American bridge under construction, the outward leaning towers making it interesting visually.

Current Long Span Bridges You can see the 2015 and 2016 LSB lecture slides on slide share to see the progress on many of these bridges. I will update this lecture for next year, if you are aware of an interesting LSB under construction please let me know via Linkedin. David Collings BSc CEng FICE Making the complex simple
