While surveying Lower Cradle Hole Cave, one caver sent a floating candle downstream along the river, until it floated under a low ceiling out of sight at the end of the known passage. On plotting the surveyed passage on a map alongside Marble Arch Cave, it was apparent that only 9 metres (30 ft) separated the end of this passage from the upstream end of the Grand Gallery, and it was postulated that a connection between the two might be forged. 54: 729: 76: 590: 597: 83: 604: 654: 642: 630: 618: 577:. Kozłowski made the first connecting dive to Prod's Pot – Cascades Rising, doubling the total length of the system from 4.5 to 9 km (2.8 to 5.6 mi). Subsequently he and Chris Jewell connected the newly established Monastir Sink – Upper Cradle system, extending the Marble Arch system to 11.5 km (7.1 mi). The discoveries make this the longest cave in Northern Ireland. 417:. In wet conditions, the cavers re-entered Pool Chamber via the entrance found in 1908, and after some investigation discovered a high-level crawling passage exiting the chamber. The passage ended high in the wall of New Chamber, a cavern of considerable size, where the upstream continuation of the river was found. Exploration was halted here as the water was too deep to pass. 527:
The development also included boring a new entrance shaft into Skreen Hill and, significantly, excavating a corridor using quarrymens' plugs and feathers (instead of potentially damaging explosives) through the short section of rock separating Pool Chamber from New Chamber. This connected Skreen Hill

From 1982 until after opening in 1985, sections of Marble Arch Cave underwent development to improve accessibility in order to accept tourist visitors. As well as concrete pathways, safety barriers and electric lighting, this involved installing weirs and jetties for boat access to enable visitors to
