The Blair Street Bridge is a concrete and steel girder bridge carrying the Lyell Highway through the township of New Norfolk across the River Derwent in Tasmania, Australia. Serving as a vital transportation link in the township's infrastructure, the bridge features a single carriageway[3] with separated shared-use pathways on both sides.[4] Completed in 1974, it is the fourth bridge to be constructed at New Norfolk, with the development aimed at withstanding valley floods before the establishment of the Meadowbank weirs.[5][note 1]
