Road ecology blog: wildlife guard and gate at access road

May 07, 2012  •  Leave a Comment

A few weeks ago I showed images of a wildlife guard that was constructed with modified bridge grate. Modified bridge grate is more comfortable to drive over than the bars or tubes used in standard cattle guards. Bridge grate material is typically used where traffic volume and vehicle speeds are relatively high and if there is relatively frequent use by bicyclists and pedestrians. However, a wildlife guard constructed with bridge grate material is more expensive than one that uses standard metal bars or tubes. The image below is an example of a standard wildlife guard. In this particular context its purpose is to discourage white-tailed deer and other ungulates from accessing the fenced road corridor. Click here for additional images, including photos of a gate next to the wildlife guard. The gate allows pedestrians or cyclists to pass through the fence.
