Two junctions existed on the canal, connecting the Peckham and 'Croydon' sections

Both the Grand Surrey and Croydon companies intended upon having a junction with the Thames at Rotherhithe. The Croydon Canal soon settled for a junction to be made with the Grand Surrey at Coldblow. Thus until 1836 Croydon boats shared the Thames connection with the Grand Surrey and there was a lot of friction between the two companies. The Grand Surrey's main trade was in timber and not surprisingly the Croydon often complained of obstructions to traffic from floating logs that were stored in the Grand Surrey's waters.
The Grand Surrey acquired the stump belonging to the Croydon Canal soon after that canal's closure. The passage of time saw this small remnant of the Croydon eventually reduced to nothing more than a mere wharf, although widened, as seen below, by the London and Croydon railway in order to provide an interchange point with the Grand Surrey. It was last in use around 1965 and subsequently filled in.

The colour picture shows the junction of Surrey Canal Road and Mercury Way, along whose alignment the Croydon canal ran. The Grand Surrey, although having closed in 1971, remained watered for a few years after closure. It was subsequently infilled during 1978, ultimately becoming the Surrey Canal Road.

A mooring bollard still exists at this point, as the picture shows. Some of these were evidently more suited for ships.

Walk forms a linear parkway that stretches from Peckham to Camberwell.

There is virtually no trace of the canal from here eastwards to the Old Kent Road.
Looking to the junction from the Peckham Branch.
A view along the canal alignment westwards. The junction is in the foreground. It can be said that one can see the entire length of the former canal route from here to Camberwell. (In the distance can be seen the lattice footbridge, the church and blocks of flats in Camberwell)
Parts of the old canal wall can be seen at the junction. On the right of the wall would have been the water, on the left the towpath
