The 'Once a year' Bridge.

Each year over the August Bank holiday weekend, the Reading Festival takes place. It is a huge event and there is a lot of activity on the site for many weeks leading up to it. Featured in todays Blip is a bridge which is constructed each year over the Thames linking the main site with car parking and camping areas. It is quite impressive and they have it down to a fine art each year now. Once they have gone,  all that remains is a base either side of the river which the bridge bolts on to and even this is covered with earth so is more or less invisible.
