What's it all about? Bridges to Africa is a sponsored walk involving students from schools across London and the UK. Students join together to walk over 10 bridges of the Thames, from Vauxhall to Tower bridge in Central London. The money raised by students is used to help build a new affordable secondary school in Uganda, through the charity PEAS.
