The Fairway Drive Grade Separation Project will lower Fairway Drive under the two existing Union Pacific Railroad (UPRR) and Metrolink tracks in the City of Industry and unincorporated area of Los Angeles County, immediately north of the 60 Freeway. Plans call for constructing a four-lane roadway underpass and a new four-track railroad bridge. Business Parkway and Walnut Drive North will be lowered at their intersections with Fairway Drive. A construction contract was awarded in October 2014 and preliminary work began in April 2015. Major construction activities began in June 2018 with the closure of Fairway Drive. Project cost is estimated at $232.3 million.

The project would reduce traffic congestion by an estimated 27.6 vehicle-hours of delay each day at the crossing, used by 49 trains per day, projected to increase to 91 trains per day by 2025. Fairway Drive carries 24,800 vehicles per day which is projected to increase to 26,500 vehicles by 2025. The project would eliminate delays for emergency responders and the potential for crossing collisions, with seven crossing collisions recorded over the past 10 years. The project would also reduce emissions and eliminate locomotive horn and crossing bell noise at the crossing.
