What is the main approach from Belfast to Bangor along Belfast Lough?

The A2 is the principal Belfast-to-Bangor road corridor through the Holywood side of Belfast Lough.

TrafficWatchNI lists cameras at Tillysburn, Holywood Esplanade, Holywood Exchange and Rathgael, so a driver can check different parts of the approach. If you are going to Bangor seafront, its car parks lie away from some residential and retail destinations; enter a specific parking location rather than expecting “Bangor” to lead directly to the marina.
