Metro will temporarily close select lanes and ramps along I-105 to install new overhead sign structures for the I-105 ExpressLanes Project in South Los Angeles County. The closures are a necessary step in converting existing carpool lanes into dual ExpressLanes in each direction between the I-405 and I-605 freeways, a transformation designed to deliver faster, safer and more reliable commutes, including cutting travel times in half for ExpressLanes users.
