In the begining plans for the canal anticipated a connection with the Thames, thus it was known officially as the Croydon and Rotherhithe Canal. The Grand Surrey Canal Company were the ones who made the river connection and the Croydon company had to settle for a junction near Coldblow Lane, in the vicinity of New Cross. The un-named location for want of description and consistency with the Grand Surrey feature was entitled Coldblow Junction by London Canals. It is sometimes referred to as the junction near Hatcham
After closure of the Croydon Canal, the route as far as Lock 1 became the Coldblow branch off the Grand Surrey. This final remnant of the Croydon was eventually reduced to a mere wharf, whose task was to provide an interchange point between the London and Croydon railway and the Grand Surrey Canal. The Coldblow section was last used about 1965

The colour picture shows the junction of Surrey Canal Road and Mercury Way. The Grand Surrey, closed in 1971, remained watered until infilling during 1978 for the new Surrey Canal Road. The alignments of the two pictures are very similar. The pavement on the right hand side of Mercury Way is the centre of the canal, and it ran through where the car park and lawns for housing on the right are. It rejoins the road's alignment further along. An article in Canal Boat & Inland Waterways for December 2003 (p82-83) featured the Grand Surrey Canal - it claimed that the junction of the Croydon and the Grand Surrey is where Juno Way now meets Surrey Canal Road - this is on the wrong side of the railway!
Upon seeing this old picture, it did not seem possible this was Coldblow.A survey of the area confirmed that this picture depicts the former junction with the Croydon Canal. One puzzle is the railway at the back of the photograph. This seems to dive under the canal.. In fact it went through a short tunnel under the London and Brighton line at a lower level than the canal itself. This tunnel is shown below, and served a branch to Deptford Wharf (opened 1849 closed 1964.)

Railway bridge and Myers Lane, SE14
It is a bit difficult to keep track here, but bear in mind that the first pictures looked southwards along the canal route. This is Myers Lane, picture above left, which is part way along Mercury Way, and this is the view looking back towards the junction along the canal alignment. Mercury Way is out of sight behind trees on the right.The next picture (above right) is the approximate extent of the Coldblow Cut as seen in the black and white view. The location is identifable because almost directly behind is the entrance to the railway tunnel discussed earlier, and the railway followed the alignment where the cyclist can be seen, as it crossed the picture to enter the tunnel.

Mercury Way - one of the dustiest roads in London?
In dry weather Mercury Way must be one of the filthiest roads in London due to the number of lorries. These pictures, with lorries parked, show where it makes a 's' bend into the canal's alignment. Mercury Way now uses the canal line as far as Coldblow Lane
