|Route outline (key)|
Turning off the A1 as it becomes the A16 the A17 almost immediately enters the St Helier Tunnel under Fort Regent. After leaving the tunnel, there is a large roundabout with the B79, which appears to be the eastern flank of the ring road. After a signallised crossroads with the A15, the road descends into Georgetown. It ends when the A3 merges in just before a 6-way junction with the A3 bearing left and the B47 to the A5 and A4 heading straight on.
