Unmanned aerial vehicles (UAVs) are increasingly employed for numerous public\nand civil applications, such as goods delivery, medicine, surveillance, and\ntelecommunications. For the latter, UAVs with onboard communication equipment\nmay help temporarily offload traffic onto the neighboring cells in\nfifth-generation networks and beyond (5G+). In this paper, we propose and\nevaluate the use of UAVs traveling over the area of interest to relieve\ncongestion in 5G+ systems under spontaneous traffic fluctuations. To this end,\nwe assess two inherently different offloading schemes, named routed and\ncontrolled UAV `bridging'. Using the tools of renewal theory and stochastic\ngeometry, we analytically characterize these schemes in terms of the fraction\nof traffic demand that can be offloaded onto the UAV `bridge' as our parameter\nof interest. This framework accounts for the unique features of millimeter-wave\n(mmWave) radio propagation and city deployment types with potential\nline-of-sight (LoS) link blockage by buildings. We also introduce enhancements\nto the proposed schemes that significantly improve the offloading gains. Our\nfindings offer evidence that the UAV `bridges' may be used for efficient\ntraffic offloading in various urban scenarios.\n
