A minute's silence will be held tonight in memory of a mother and newborn daughter found dead after going missing from a maternity hospital.
The bodies of Charlotte Bevan, 30, and her daughter Zaani Tiana, were discovered on the Avon Gorge, close to the Clifton Suspension Bridge.
Numerous floral tributes to the mother and baby have been placed on the road overlooking the bridge, which is celebrating its 150th anniversary.
At 7pm tonight, a minute's silence will be held before a dazzling firework display is launched from Isambard Kingdom Brunel's bridge, as well as a charity collection.
The fireworks are the beginning of anniversary celebrations for the bridge, which joins Bristol to North Somerset and was designed by the engineer in 1829.
On Monday, a special procession will provide a re-enactment of the opening ceremony 150 years ago, finishing at the new Suspension Bridge Visitor Centre.
Calls to cancel the celebrations had been made following the discovery of Ms Bevan's body on Wednesday and her daughter Zaani the following day.
But in a statement, the Clifton Suspension Bridge Trust said trustees had spent 48 hours carefully reviewing the situation and decided to go ahead.
"Having thought very deeply about this, it is felt that the planned event should go ahead," the statement said.
"The loss of Charlotte and Zaani, as well others who have previously died in the Avon Gorge, will be marked by a minute of quiet and reflection prior to the start of the firework display at 7pm.
"We will set up a collection with the proceeds going to a charity, which we hope to discuss with Charlotte's family at an appropriate time."
