A $22 million interchange with US 12 was completed in May 2012 to replace the intersection in Burbank that marks the western terminus of SR 124. The intersection, along with a nearby junction with Humorist Road that was replaced with an overpass, had been the sites of several fatal collisions that killed five people in the late 2000s. A railroad crossing south of the Ice Harbor Dam was replaced in October 2017 with an overpass that cost $11 million to construct and realigned a dangerous intersection with a nearby road.
