A portion of the 101 Freeway in Los Angeles will be closed for weeks in order to construct the “world’s largest wildlife crossing” bridge.

Starting Monday, Highway 101 will be closed overnight on weekdays in order to construct the bridge over 10 lanes. The bridge will allow wildlife to cross from the Santa Monica Mountains into the Simi Hills of the Santa Susana mountain range. It will also be covered with landscape native to the area in order to blend in for the wildlife.
