The Kelston toll road has been open for nearly a week now with many commuters opting to use it.
The temporary road is allowing traffic to negotiate the A431 Kelston Road, which has been closed since February because of a landslide.
Businessman Mike Watts set up Kelston Toll Road Ltd to build the 400m diversion.
The toll fees each way are £1 for a motorcycle and £2 for a car or a van. The road has a weight limit of 3.5 tonnes.
