Danbury Street Bridge

Pretty nondescript bridge. Significant as it provides reasonable ramp access down to the canal bank near to City Road Lock and Basin, and so is the disabled access point for those sites.
It’s also recommended that wheelchair and bike uses leave the canal at this point if they’ve come from that direction. The bridge does have a narrow path, and there’s only a short stretch further on before the Islington Tunnel. Though disabled or not you might want to check out the Islington Visitor Moorings.
As you walk under the bridge look along towards the tunnel. It gives the right angle to just about see the dot of daylight at the other end.
