Budapest is undertaking several major infrastructure projects affecting public transport and road access. In late September 2026, modernization of tram line 6 tracks on Karinthy Frigyes Road began, involving track replacement and temporary service changes for trams 4 and 6 through November.

Concurrently, the reconstruction of the K-híd bridge, which connects Óbuda to Hajógyári Island, commenced in mid-October 2026 following long-term delays. The project is divided into phases scheduled for completion by the end of 2027. During the initial phase, vehicular traffic is suspended to allow for roadway and southern walkway renewal, while pedestrians and cyclists are redirected to the northern walkway. Construction schedules include planned pauses during major events, such as the Sziget Festival, to maintain accessibility.
