Surface
The approach and initial climb up the bridge have a smooth asphalt surface; however, on the top of the bridge the surface was uneven and bumpy when it was built. In September 2006, it was announced that the entire bridge would be resurfaced, only five years after the last resurfacing. This was completed in November 2009 by the construction firm Stirling Lloyd. However, the surfacing was carried out by the Swiss firm Aeschlimann using its own workforce and also importing all the plant used. A new type of asphalt called Gussasphalt was used on the bridge deck. In addition to having a smooth, skid-resistant finish, it requires no compaction and can be applied in very thin layers, thus reducing the weight added to the bridge. It is also flexible and as a result should last longer than the previous resurfacing.

And her proud ephemerals,
Fast to surface and outside,
Scan the profile of the sphere;

A new genesis were here.”
