|Route outline (key)|
The B503 is a short B-road to the southwest of Belfast city centre.
The road starts at traffic lights on the A11 on the corner of the built-up College Square and heads west along College Square North to reach a mini-roundabout, where it turns left onto Durham Street. The next road to the right, Albert Street, was originally the B502 but this was declassified when the road was severed with the construction of the A12 in the 1980s.
The B503 continues south to cross the B38 at traffic lights. On the far side it climbs steeply to cross a bridge over the approach tracks of Great Victoria Street station before descending again to pass a hotel and become more residential. After crossing the unclassified Donegall Road at traffic lights the road continues south for another block towards two church spires to end at traffic lights on the A1 Lisburn Road. At this junction the B503 can only be accessed to/from the west.
As with the B502 mentioned above, the construction of the A12 forced a rerouting of the B503. The B503 now follows its original route from the A1 north to College Square North where it turns off to the right. However, originally the road continued north along the remainder of Durham Street and onto Townsend Street and Denmark Street to end on the A6 Clifton Street. This section was altered beyond recognition when the A12 was built.
