Bats and bridges

Bats are known to roost in many different locations within bridges

Roosting locations in which bats have been recorded include: expansion joints; gaps at the corner of buttresses; widening gaps; cracks/crevices between stonework and brickwork. Species regularly recorded roosting in bridges include Daubenton’s, Natterer’s, pipistrelle species, brown long-eared and whiskered bats.


Legislation now requires landowners to carry out a bat surveys prior to modification or repair of bridges suitable for roosting bats. Bridges with potential for roosting bats can be inspected during daylight hours, using a high powered torch and an endoscope. If a license is required for this work then one can be submitted prior to any inspections being carried out.
