The event on Saturday, October 17, will see the 104 girls climb to the top of the bridge.
Following the 210 step, 160ft ascent up the Transporter, the climb girls will have their photos taken, take part in a quiz and will be promoting Girlguiding.
Links between the Bridge and local Brownies go back several decades. In 1984 Brownies on Teesside took part in a national event, The Tea Challenge, which entailed serving tea in a most unusual way – atop the Bridge.
And so 31 years later, Girlguiding Cleveland has again teamed up with the Heritage Lottery Fund-supported Bridge for more celebrations.
The 1st Egglescliffe Guides are celebrating 90 years, 1st Egglescliffe Brownies and 1st Eaglescliffe Brownies are both celebrating 80 years while 27th Hartlepool marks its 60 year milestone.
The Senior Section area of Guiding made up of young women aged 14–25 year olds, are about to embark on their centenary year and were behind chosing the link-up with the Bridge.
