We present a direct bijection between planar 3-connected triangulations andbridgeless planar maps, which were first enumerated by Tutte (1962) and Walshand Lehman (1975) respectively. Previously known bijections by Wormald (1980)and Fusy (2010) are all defined recursively. Our direct bijection passes by anew class of combinatorial objects called "sticky trees". We also presentbijections between sticky trees, intervals in the Tamari lattices and closedflows on forests. With our bijections, we recover several known enumerativeresults about these objects. We thus show that sticky trees can serve as anexus of bijective links among all these equi-enumerated objects.
