During the 2 decades that followed the separation of BTNR from CCNR, nature lovers complained about the separation of biodiversity in the BTNR and CCNR. They said that animals from each nature reserve could not cross over to the other reserve, and wanted a link to connect the two reserves, so as to allow animals to move about from one reserve to the other. In 2005, some nature lovers and government authorities agreed to build a bridge to link the two reserves. Work to build the Eco Link began on 30 July 2011 and was completed in the 3rd quarter of 2013. Trees to create a natural environment were planted on the bridge after it was completed.
