Safe road crossing for small creatures and amphibians has side guide legs leading to drop-in shaft covered by grating of pitch suitable suitable for small creatures to drop to safety.

摘要

The legs (3a,3b) of the U-shaped entry shaft (5) structure run parallel to the road (2) and flush to this to act as support for the grating, using leg elements in I-beam shape so the beam webs run parallel to the shaft wall. The grating is slid on from the side, with grating bar pitch to let creatures through and down. The shaft walls stand vertical to a V-grooved shaft bottom for water runoff.
