A system of directional signs is in operation for the delivery of goods to the city Centre. These routes were developed in consultation with haulage groups, and if followed correctly, it will allow goods drivers to use the most suitable routes and avoid unnecessary mileage and delays.
How it works

An example would be;
If you know you are delivering to a store that uses service area G1
Look first for the sign with the letter G
Most delivery vehicles approach the City Centre from the West
Follow the G signs until you reach the area near to your collection/delivery point; then follow the signs for G1.
Make sure the Store tells you which delivery area they use.
