The abutment houses a winter stay in the form of a labyrinth of linked ‘cavity zones’. Both on the underside of the bridge deck and in the masonry of the balustrade, there are summer stays. In the brick bridge wall and in deep caverns in the underside of the bridge deck, there are warming nesting zones. The behaviour and the needs of the bat species were included in the design of the different stays.

Concrete was chosen for the construction, a material that because of its mass ensures a stable temperature and a pleasant climate. The roosts are located in slits that are part of a pattern of grooves in the concrete arch. The bats can reach
