A permanent zipline could be built across the River Lagan in Belfast.
The development is part of proposals to create a lively riverside with better pedestrian links along the east bank of the waterway and into the city centre.
Social Development Minister Nelson McCausland published the plans for Queen’s Quay.
He said: “Once completed, these new proposals will benefit a wide range of Belfast’s citizens and visitors, from cyclists to tourists to outdoor activity enthusiasts, including the innovative proposal for a permanent zipline across the Lagan.
“The Queen’s Quay Masterplan will enhance the economic and social development of Belfast’s riverfront, its city centre, and adjacent neighbourhoods to the north and east of the site.
“Queen’s Quay is the final stage of redevelopment of the Laganside area and this plan will complete a 25-year transformation of the area.”
In the short term, the department will upgrade the Lagan Walkway Bridge and provide a zipline and viewing tower, make improvements for cyclists and create grassy public spaces.
Later phases of the plan propose a four-star hotel, houses and restaurants along the waterfront.
