London bridge to meet needs of all
Designs have been unveiled for a new bridge across the Thames in London - thought to be the first in a major city centre to incorporate the needs of both cyclists and pedestrians.
Four proposals for the bridge were shortlisted from 74 initial entries in March.
The bridge must be high enough to allow large boats to pass below, but not too steep for pedestrians and cyclists to climb.
The designs must also enable movement by bikes and walkers in both directions at peak times.
