There's currently an exhibition entitled:
"Places & Spaces: Urban Realm and Development on the Crossrail Route"
in the RIBA building at 66 Portland Place, W1B 1AD
http://www.architecture.com/whatson/...i lroute.aspx

It's all about the urban spaces around the Crossrail stations, rather
than the railway or the stations themselves. For example, it shows how
the increased pedestrian flows will be accommodated.

Not surprisingly, considering the venue, the text on the posters is
heavy on architectural jargon, but it's worth spending half an hour
there if you get a chance. However, it's only open at that venue for a
few more days, so if you don't get a chance to visit, here's some pics
I took this morning:

There will be another chance to see it in person when it moves to The
Building Centre, 26 Store Street, London, WC1E 7BT from 21 July to 14
August.
