This article is about the Class III road numbered C604 maintained by Angus Council. For other roads numbered C604, see C604.
The C604 comprises a selection of streets in the centre of Arbroath, which almost form a box around the main shopping area. There is no easily defined start or end point, but working clockwise, the route includes: West Abbey Street, Abbey Path, Lordburn, with spur to the A92, Gravesend, Brothock Bridge - again connecting to the A92, Commerce Street and Hill Street, the last two of which are one-way westbound. Commerce Street was also previously part of the B9114.
